Depending on the year of your car, the transmission fluid drain plug will be a 17mm lug (02-05 i think), or a TORX T-70 star shaped lug (06+ i believe). Either way, it will be one of those. 17mm sockets are easy to find anywhere, but a TORX T-70 is literally impossible. Short Shift Kit Adjustable Product Description. AVOTurboworld's short-throw quickshift gearshift lever reduces the distance required to shift gears from one ratio to the other, this makes changing gears a more natural 'flick of the wrist'.

They were introduced in 1989, intended to succeed the previous. The EJ series is the mainstay of Subaru's engine line, with all engines of this series being 16-valve horizontal, with configurations available for single, or double-overhead camshaft arrangements ( or ). And versions are available, ranging from 96 to 320 hp (72 to 239 kW; 97 to 324 PS). These engines are commonly used in light aircraft, and into air-cooled Volkswagens, and are also popular as a swap into the engined.
Primary engineering on the EJ series was done by Masayuki Kodama, Takemasa Yamada and Shuji Sawafuji of, Subaru's parent company.

Impreza WRX STi 1998present (JDM, specifically homologation models for )EJ20X/EJ20Y Based on the same engine platform; the X designation indicates an automatic package, and the Y designation indicates a manual package. The EJ20X engine was introduced in the 2003 Legacy GT, mated to a five-speed automatic transmission, and the EJ20Y engine was introduced in the 2004 Legacy GT, with a five-speed manual transmission.The EJ20X and EJ20Y are open deck engines whereby the cylinder walls were supported at the three and nine o’clock positions.
It came with an aluminium alloy block with 92 mm (3.62 in) bores – with cast iron cylinder liners – and a 75 mm (2.95 in) stroke for a capacity of 498.6 cc (30.43 cu in) per cylinder, with thicker cylinder walls than EJ25.The crankcase for the EJ20X and EJ20Y engines had five main bearings and the flywheel housing was cast with the crankcase for increased rigidity. The EJ20X engine is understood to have a forged crankshaft and connecting rods, but cast aluminium pistons with forged crowns.The EJ20X and EJ20Y engines had an aluminium alloy cylinder head with cross-flow cooling, double overhead camshafts (DOHC) per cylinder bank and four valves per cylinder that were actuated by roller rocker arms.The EJ20X and EJ20Y engines were equipped with Subaru's ‘Dual Active Valve Control System’ (‘Dual AVCS’) which provided variable intake and exhaust valve timing. The Legacy GT, the EJ20X engine was fitted with a twin-scroll IHI VF38 turbocharger; the EJ20Y engine, however, had a larger twin-scroll Mitsubishi TD04 HLA 19T turbocharger. For the revised BL.II Legacy GT, both the EJ20X and EJ20Y had an IHI VF44 turbocharger for the initial 2006 model year, replaced the following year with the IHI VF45.Both came with a 9.5:1 compression and a fast spooling turbo yields a torque filled performance. 265–280 bhp (198–209 kW; 269–284 PS)Turbos:.

Flat four EJ251The EJ251 was the first version of a long line of single overhead cam engines by Subaru for the US market. The EJ251 was soon replaced by the in many models due to its improved cooling to aid in head gasket life and improved engine management and sensors. The EJ251 commonly experienced head gasket failures resulting in interior channel breaches or exterior fluid leaks due to the continued use of a single layer coated gasket first introduced on the EJ25D.

They are most commonly found in MY00 Legacy Outbacks manufactured before the end of 1999 while MY00 Legacy Outbacks manufactured in 2000 are rarely designated with EJ252 codes in the VIN. While Subaru has not provided a direct list of revisions between the EJ251 and less common EJ252, there is some degree of information suggesting the EJ252 was simply an alternate version of the EJ251 made to meet California Emissions Standards when the SOHC EJ engines were first introduced in North America.
Power output has been reported as ISO 115 kW (156 hp) but is often speculated to share the same specs with the largely identical EJ251. From unofficial analysis, the EJ251 shares the same with block, cams, heads, pistons, connecting rods with the EJ252. The only notable differences confirmed are unique intake manifold and throttle body designs to accommodate the different MAP sensor location and IACV location.

Contents.History Pre-facelift: 2000–2002 Built on a significantly modified version of the, the new Impreza followed much the same formula as its predecessor, including a similarly contoured silhouette. Despite this, the front-end styling—distinguished by ovoid —attracted significant controversy. This version of the Impreza has gained the nickname 'Bug Eye' among Subaru enthusiasts.
Body dimensions for the sedan increased by 45 mm (1.8 in) in length, 40 mm (1.6 in) in width, and 25 mm (1.0 in) in height; increased by 5 mm (0.2 in). To satisfy, the width of the hatchback increased by just 5 mm (0.2 in) to 1,695 mm (66.7 in) and therefore remaining in the limit '5' classification. As Subaru had intended to homologate the sedan chassis for, the decision to increase the width of the sedan—which placed it into the higher taxed number '3' division—brought added stability. Likewise, the 20 mm (0.8 in) increase in track for the sedan also worked to aid handling, with the hatchback gaining just 5 mm (0.2 in). Other main improvements to the chassis included a 120 percent increase in torsional rigidity; mainly due to revisions in front subframe design. The suspension retained its basic in the front and rear, although Subaru altered the geometry.The GD chassis gains nearly 200 kg (441 lb) in weight over the GC chassis. Subaru claims that compared to the previous model, the GD chassis is 148 percent and 82 percent stiffer in torsional and beam rigidity, respectively.
This stiffness is primarily due to the addition of a steel 'ring' which encircles the cabin at the B-pillar. While the stiffness was increased for passenger safety, it has the added benefit of providing more stability for motorsports events. Firehouse magazine notes that the need to cut the Subaru's B-pillars at certain points in order to cut through the car frame. In terms of safety, the GD chassis scored much higher than the GC chassis and earned a 'Good' rating (highest mark) from the 's offset crash test. 4 stars front driver, 5-star front passenger and 4-star side safety ratings from the.In Subaru's home market of Japan, the Impreza range started with the 1.5i—powered by the 1.5-liter EJ15 engine and paired with a or optional. Subaru fitted a version of the same engine to the automatic-only 1.5R, which also featured an.
For both models, front- and all-wheel drive versions were available. Starting from 2006, Subaru phased out the EJ15 engine in favour of the new EL15.Subaru released this generation of Impreza to North America in 2001 for the 2002.
The release of the 169 kW (230 PS; 227 bhp) 2.0-liter turbocharged Impreza WRX, did not occur until the 2002 model year, and the Impreza WRX STI was delayed until the 2004 model year. The US version of the STI includes various departures from the Japanese and European counterparts, such as a turbocharged 2.5-liter EJ257 engine, rather than the 2.0 L engine sold elsewhere.
All 2006 American Imprezas use some form of the 2.5-liter EJ25 engine since naturally aspirated and turbocharged are available.The Outback Sport was sold in Australia for model years 2001–2007, but it was renamed as the Impreza RV with the same color scheme as the American version. The Australian version had a, not available in the United States. The Impreza was magazine's for 2000. Hatchback (pre-facelift)First facelift: 2002–2005 After mixed reaction to the round headlight design, in 2001 Subaru enlisted the help of of, who updated the car's fascia in 2002 (2003 in the US for the 2004 model year), with more rectangular headlamps.
For the US market, the facelifted Impreza was offered as 2.5 RS Sedan and TS Wagon, 2.5 Outback Sport Wagon, WRX Sedan and Wagon, and the new WRX STI Sedan. Sport Package was optional for the RS, and the WRX could be ordered with Premium Package. The RS, TS, Outback Sport, and WRX are available with manual or automatic transmission, while the sole transmission for the STI is 6-speed manual. This version of the Impreza has gained the nickname 'Blob Eye' among Subaru enthusiasts.In 2005, Subaru made their standard on all engines used in the Impreza.
Second facelift: 2005–2007 From June 2005 in Japan (2006 model year) Imprezas have been redesigned, along with new headlights, taillights, and bumpers. Greek designer, formerly of, penned the updated front-end in 2004. The facelift introduced Subaru's new corporate face, including its controversial 'jet intake and wings' grille design that first appeared on the. The new corporate face was designed to pay homage to their aircraft manufacturing roots, the.
This version of the Impreza has gained the nickname 'Hawk Eye' among Subaru enthusiasts. Pre-facelift Subaru Impreza WRX sedan (US)In December 2000, Subaru updated the WRX to the second generation. The GDA WRX model also retained the 5-speed manual transmission gearbox design from the GC8. Subaru later released a new 6-speed gearbox for the STi model GDB that is significantly stronger.The GD chassis along with the WRX and STI underwent two styling changes in its life cycle. The original styling applied to A and B. Initially this design proved to be rather unpopular which prompted a more conventional design for the applied C, D and E models.
The second facelift applied to the F and G versions.The WRX STi gained 17' x 7.5' over the previous 16' x 7' wheels. The 5 speed (reputed to be one of the car's weak points) was changed to an STi engineered 6 speed. The engine was retained from the Version 6 STi and still retains the semi-closed deck block and is still labelled as the, however the engines did gain Variable Valve Timing (AVCS) further improving their low-end torque production. The interior was updated with an STi logo on the gauge. The STi's tachometer also has a red. The STi's and optioned Type RA STi have received 4 piston front and 2 piston rear brakes while the bare-bones Type RA STi still carried the Subaru 4 piston front and 2 piston rear brakes. Externally, the STis had larger and had covers with STi embossed on them.
The DCCD was updated so it can work with. During braking, when the is on, the DCCD will set itself to open-mode (no locking).The version nomenclature was dropped from the name.
Japanese and other auto-enthusiasts often refer to the chassis as GDB/GDF (the STi has a 'B' or 'F' (for USDM models) whereas the regular WRX had an 'A'). The fourth character of the VIN gives the revision (A to F where G is the 2007 version).In 2000, most of Asia, Oceania and Europe received the new STi.
The engine was to meet. Engine output was variously rated from 265 PS (261 bhp; 195 kW) at 6,000 rpm and 343 N⋅m; 253 lbf⋅ft (35 kg⋅m) of torque at 4,000 rpm, to 280 PS (276 bhp; 206 kW) at 6,400 rpm and 373 N⋅m; 275 lbf⋅ft (38 kg⋅m) of torque at 4,000 rpm depending on market.2005 STis received the long-awaited DCCD control available in other markets, as well as a slight wheelbase increase to match the Japanese-spec WRX STi Spec-C and has 280 PS (210 kW; 280 hp).Japan.

It is powered by an EJ205 with AVCS coupled with an IHI TD04-HL. The engine produces 250 PS (180 kW; 250 hp) at 6,000 rpm with 35 kgm (246 ftlbf, 333 Nm) at 3,600 rpm. The wheels are 16 in (410 mm) in diameter.
The car uses 2 pot/1 pot front and rear brakes. The front brake rotors are ventilated while there are rear solid disks. It has a rear LSD and a 4.44 final drive ratio. The transmission has close-ratio gears unique to Subaru of Japan at that point in time. The car has a curb weight of 1,340 kg (2,954 lb).The WRX Type RA STi was produced. The STi wagon was still produced, although it retained the 4 pot/2 pot calipers from the previous model STi and featured narrower 17' wheels from the Legacy.
The STi foglight covers had white STi lettering on them. The WRX Type RA STi was used for the.Applied B (2001)The 2002MY WRX NB sedan debuts on September 2001. The mechanical specifications are similar to the previous year's model but the curb weight has been increased to 1,350 kg (2,976 lb).Along with the rest of the Impreza line, the and body of the WRX STi was lightly updated by to give it a more angular look when seen from the side. The fog light covers had pink STi lettering. Not much else besides minor suspension improvements and a small increase in output were done.The WRX Type RA STi was dropped for a new WRX STi Spec C.
This model was much lighter than the WRX Type RA as it received lighter glass. The Spec C's handling was much improved due to an increase in (from 3.5 degrees to 5 degrees). This was achieved not by changing the suspension mounting point, but by lengthening the wheelbase by 15 mm (0.6 in). This was done by including different. This increased caster significantly helped the turn-in capabilities of the car. The Spec C also has a steering rack ratio of 13:1. The transmission is supplied with its own.The WRX STi wagon had ceased to be produced.Applied C (2002)The WRX NB-R sedan is released in November 2002.
The power and torque ratings are the same as the previous year. The wheel diameters are increased to 17' in size. The rear brake rotor is changed to a ventilated disk, leaving the car to use only ventilated disks for braking. The car has 4 pot/2 pot front and rear brakes.
The rear wing is on wing risers. The car now weighs 1,361 kg (3,000 lb).The WRX STi was used for.Applied D (2003)The WRX line receives a body exterior update and an improved transmission.
The WRX STi is now capable of being ordered with DCCD.The WRX STi Spec C Type RA was released. It sported a wing and a carbon fiber lip. It also had a new set of wheels as well as a newly tuned engine.The WRX STi V-Limited was released. It sports 4-way dampers tuned by Subaru World Rally Team's Group N driver. The WRX STi was used for.Applied E (2004)The WRX WR-limited is introduced. The car receives an STI spoiler and an STI front chin.
There is a WR-stickered titanium shift knob. The wheels are changed for STI, gold-colored Rays-sourced wheels.This was the first Impreza STi model to be offered in the United States.
Subaru unveiled this model at the Detroit International Auto Show, only 1 month after Mitsubishi announced the arrival of the 271 horsepower Lancer Evolution 8, which out-performed the 2.0L WRX.Applied F (2005)The WRX has an option to receive the same spoiler as the WRX STI. The WRX has a viscous rear LSD now.The WRX STi receives the same increase in wheelbase as the Spec C. All STis received additional rear arch flaring in order to allow an increase in wheel size. The wheel size changed from 17' x 7.5' to 17' x 8'. In accordance with the increased wheel width, steering lock-to-lock turns have been reduced.
Wheel hub strength was improved. Was changed from 5 x 100 mm to 5 x 114.3 mm. The interior was vastly improved as well. A whole new now brings out a very high grade interior feel.The WRX STI Spec C's receives the tuned dampers and a 21 mm (0.8 in). The rear suspension is changed from rubber bushings to bushings.
The was further stiffened for improved handling and stability. The strut towers were reinforced for better handling and better ride characteristics. The engine mounts were changed from metal to liquid-filled plastic mounts to reduce vibrations into the car's cabin. Some 2006 owners have had issues with these plastic engine mounts. The manufacturer will replace them, under warranty if broken, with the 2005 rubber mounts. The DCCD is updated with the use of a torque-sensing mechanism inside the DCCD. The torque split is changed to 41/59.

( July 2018) Applied A (2000)WRX's initial release date 2000.Applied B (2001)North America receives its first Impreza WRX models. They are equipped with an EJ205 engine rated at 227 hp (169 kW) at 6,000 rpm with 217 lb⋅ft (294 N⋅m) of torque at 4,000 rpm. Unlike the Japanese EJ205, the US-spec engine uses a Mitsubishi TD04-13T turbocharger unit. In stock form, it reaches a peak 13.6 psi (0.9 bar) of boost. The seats are the same as the basic J-spec Impreza.
The wheels are cast 16' x 6.5' version of the J-spec WRX NB wheels while the brakes are 2-piston/1-piston front and rear with the front rotors being ventilated disks. 2002 WRXs came with brake duct plates that guided the air in the front bumper vent to the wheel well.
The gear ratios are the standard export models, but the final drive is a 3.9:1 ratio. The rear LSD is a viscous coupling type. The steering rack has a ratio of 16.5:1. The 4 gear electronic automatic transmission (4EAT) WRXs have a Variable Torque Distribution AWD system instead of the conventional viscous coupling center differential. VTD employs an electronically controlled hydraulic transfer clutch and a planetary gear center differential to distribute power in a 45:55 split between the front and rear axles under normal circumstances. The VTD system uses multiple sensors to measure front and rear driveshaft speeds, throttle position and gear selection.
Then it actively transfers power accordingly between the front and rear wheels for optimum traction and handling. The WRX weighs 3,085 lb (1,399 kg). Applied C (2002–2003)There are few changes from applied B. The gears are changed to RA-width gears (1 mm increase in size) to increase durability of the transmission. There is also a valve that prevents 'drop-clutch' starts in an effort to reduce the number of shattered gear boxes from abusive AWD launching. The ignition ring is now illuminated with green lighting.
Early 2002 WRXs had brake duct plates. At the end of calendar year 2002, the brake duct plates were no longer equipped on the WRXs. A shorter metal fuel pipe and longer connector hose were implemented under the intake manifold to avoid fuel leaks at freezing temperatures.Applied D (2004). 2004–2005 Subaru Impreza WRX wagon (US)The WRX received the same Peter Stevens-designed facelift that rest of the Imprezas received.
The WRX uses the same contoured seats as the 2004 US-spec WRX STI. The WRX is equipped with multi-phase valve struts to improve ride quality while retaining good handling. The tachometer was moved to center, and the speedometer was moved to the right.In 2004, Subaru of America announced it would sell the WRX STi. Subaru Tecnica International's president said in an interview with Road & Track magazine that he wished to beat the in the US. Thus, each iteration of the US-spec WRX STi is essentially the same as the respective J-spec STi Spec C. All part numbers matched up, including the part-numbers for the glass windows.
However, instead of the, the United States receives the first, a 2.5-liter version of the EJ207. Unlike the EJ207, it features cast.According to Subaru USA, this latest STi piston is a cast aluminum design. However, this is a special hypereutectic material and it has an augmentation of 120% in terms of strength over their previous aluminium pistons. The is the standard STi's 15.2:1 instead of the Spec C's 13:1Applied E (2005)The WRX received an updated interior, body color rocker panels, black painted headlamp bezels, and wheels that were previously seen on the base US-spec Legacy and a single-port exhaust. Some WRX models have an STI hood scoop that is much larger than other WRX scoops.
The suspension has also received a few small updates to make handling more efficient compared to the 2004 model. Cassette players in the stereo system were no longer offered. 2005 Subaru Impreza WRX STI (note the coloured rocker panels for the 2005 model year)As with the Japanese-spec C models, US-spec STis received additional rear fender flaring in order to allow an increase in wheel size. The wheel size went from 17' x 7.5' to 17' x 8'.
In accordance with the increased wheel width, steering lock-to-lock turns have been reduced. Wheel hub strength was improved. Was changed from 5 x 100 to 5 x 114.3. The Suretrac front LSD in the 2004 model was replaced with a helical unit, the rear differential remains the same clutch type unit. Torque split is set at 35/65. In the interior, the Stereo became standard.
The badging has been revised and different look was given to the steering wheel, shift knob, HVAC controls, and center console.SAAB 92X (2005-2006)released its, from its 9-2X line, which is essentially a re-skinned Impreza WRX Wagon of the same model year. The Linear gets the 2.5-litre four-cylinder rated at 165 horsepower, while the Aero, like the WRX, has the 227-h.p., 2.0-litre turbo engine that provides ample snap when the turbocharger kicks in at about 3,000 r.p.m. Both 9-2X models have full-time all-wheel-drive and such expected features as CD player, air conditioning and remote entry. The Aero adds 17-inch wheels, climate control, heated seats and mirrors, sunroof and six-CD changer. Options include a four-speed automatic transmission (both models come with a five-speed manual), and leather seats and door inserts.
Applied F (2006). 2006–2007 Subaru WRX wagon (US)For 2006 the Subaru Impreza WRX received a complete front-end re-design, boldly styled headlights with smoke-tinted lenses, a three-section mesh-type grill, and distinguished new tail lamp clusters. Three trims levels are available: WRX TR (Tuner Ready), WRX, and Limited. The car's curb weight is 3,140 lb (1,424 kg) for the WRX TR, 3,192 lb (1,448 kg) for the WRX, and 3240 for the WRX Limited.The biggest change was the 2.5-liter turbocharged intercooled EJ255 engine, producing 230 hp (172 kW) at 5600 rpm. It replaced the 2.0-liter EJ205 engine used since the WRX model's introduction.
The larger-displacement engine produced 235 lb⋅ft (319 N⋅m) of peak torque at 3,600 rpm, compared to 217 lb⋅ft (294 N⋅m) at 4,000 rpm for the previous WRX. Performance was improved in all speed ranges, with greater emphasis on low-end and mid-range torque. The 2.5-liter WRX engine shared architecture and technology with the WRX STI engine, including Subaru Active Valve Control System (AVCS) variable valve timing and an Electronic Throttle Control system. The turbocharger remained the same unit as on the 2002-2005MY US-spec WRXs, but peaked at 14.8 psi (1.0 bar) of boost. The first gear in the transmission received dual-ring synchros to improve downshifts from 2nd to 1st and reduce notchiness.2006 Impreza WRX models gained some chassis and braking system enhancements. On sedan models, aluminum front suspension lower A-arms reduced unsprung weight. (The rear suspension gained forward aluminum lateral links in the 2005 model year.) The steering rack was updated for improved steering feel and the steering rack ratio was changed to 15.0:1.

On all WRX models, 7-spoke 17 in × 7 in (430 mm × 180 mm) aluminum-alloy wheels replaced the previous 5 spoke 16 in × 6.5 in (410 mm × 170 mm) wheels. Tires were 215/45ZR17 versus 205/55R16 before. The more powerful brake system employed 11.5 in (292 mm) vented front discs and four-piston calipers instead of the previous versions two-piston calipers. The rear brakes were 11.3 in (287 mm) ventilated discs replacing the previous 10.3 in (262 mm) solid discs, and two-piston calipers replacing single-piston calipers. The calipers are painted red with the SUBARU name in white overlain.The US-spec STIs receive the same facelift as the Japanese-spec STIs. Mechanically speaking, the DCCD (Driver Controlled Center Differential) and the engine mounts have been changed. Like the Japanese-spec STIs engine mounts were changed from metal to liquid-filled plastic mounts to reduce vibrations into the car's cabin.
The manufacturer will replace them, under warranty, if broken, with the 2005 rubber and metal mounts. Later 2006 vehicles were equipped from the factory with 2005 mounts. The center differential is updated with the addition of a mechanical limited slip mechanism to supplement the electromagnetic DCCD. The torque split is changed to 41/59. The oil pump within the transmission was also deleted.
The 2006 STI weighs approximately 3,350 lb (1,520 kg). Applied G (2007)Ikuo Mori takes the place of Kyoji Takenaka as President and CEO of Fuji Heavy Industries.As a cost-cutting effort, the WRX has its aluminum suspension reverted to steel-cast pieces. The WRX and Limited trim levels receive an auxiliary audio port next to the cigarette lighter and MP3 CD playback. 2007 US-spec Subaru Impreza WRX STi Limited. Only 800 were producedIn 2007, quite a number of changes were made to the US-spec STI.
Due to Subaru's decision to reduce costs by cutting the amount of used, the US-spec STI no longer receives the J-spec Spec C control arms. The are now the aluminum ones used on the Japan-spec revision A and B non-Spec C STis. The high has been reduced, which in turn reduces the wheelbase from 100 in (250 cm) to 99.4 in (252 cm). The rear has decreased in size from 20 mm (0.8 in) to 19 mm (0.7 in). The of second, third and fourth gears have been made longer (higher ratio) in order to improve fuel economy and drivability, which inadvertently reduces drag racing times due to the ability to trap 114 mph (183 km/h) in 4th gear, without the shift to 5th. The transmission oil pump that was deleted in the 2006 model year was also brought back for the 07 model year transmission. The EJ257's have been redesigned to improve cooling, and the -filled have been deleted.
Pistons are the same as previous years. The is changed from a 90A rating to 110 amps. The rear is now a unit, considered an upgrade from the previous model's clutch type unit.
The turbo has also been changed to the VF43, which has a different actuator than the VF39. The side braces are stiffer than the 2006MY. The are once again the hard rubber mounts used prior to 2006. On the interior, there is an audio jack that replaces the, a rear center armrest with trunk pass-through and a 120 W audio system.The STI's ECU was completely re-engineered in order to meet US emissions requirements, which has caused throttle and timing issues. A secondary air pump was also added to help meet LEV2. Top Feed injectors replaced the Side Feed from the previous models.The WRX STI Limited was introduced with fog lights, leather interior, lip trunk spoiler, and optional moonroof.
It is similar to the Japan-spec WRX STI A-line, except the mechanicals of the car are based on the 2007MY US-spec WRX STI.United Kingdom. This section does not any.

It features 18 in (46 cm) -wheels in gold, Rosso P Zero Tyres, a blue Alcantara Interior or a blue leather option, UK300 floor mats, UK300 headlights, UK300 exclusive front and rear spoilers and UK300 decals.WR1 (2004)A limited edition of 1000 Japanese MY04 WRX STI's with DCCD was exported to celebrate victory in the 2003 WRC drivers' championship. 500 were sold in Europe, Australia and South Africa as the Petter Solberg edition; the other 500 were further modified by Prodrive and sold in the UK as the WR1. They had 320 bhp (239 kW) and 309.8 ft⋅lbf (420.0 N⋅m), a 0–60 mph (97 km/h) time of 4.25 seconds and a top speed of 155 mph (249 km/h) (electronically limited).
They were equipped with WRX STI springs, PZero Nero tires, mesh grilles, special Ice Blue and PFF7 Pewter wheels. The new and exhaust were not EU-, so they were fitted after registering the car.WRX 300 (2005)300 vehicles limited to the UK market were sold with Blue Mica exterior paint, 17' gold alloy wheels with 215/45 tires, branded front bucket seats, a 5-speed manual transmission and the Performance Package (PPP) all as standard equipment. The Performance Package increased power to 265 PS (195 kW; 261 hp) and 348 N⋅m (257 lb⋅ft) torque and equipped the car with a 0–60 mph (97 km/h) time of 4.8 seconds and a top speed of 151 mph (243 km/h). 12 months' free subscription to RAC Trackstar was included in the basic on the road price of £21495.00 (approx. Considering that the total on the road price of the standard non-limited edition Prodrive Performance Pack equipped Impreza WRX was £21900.00, the WRX 300 represented very good value for money.
Optional extras included an 18' P-FF7 wheel and tire package, a brake upgrade (front brakes only), a sports suspension upgrade and a special edition rear spoiler.RB320 (2006). Subaru Impreza RB320In 2006 Subaru UK release the limited edition Subaru Impreza RB320 in honor of the late, who died in 2005 from cancer. Richard won the 2001 WRC Drivers Championship for SWRT.The RB320 was available only in Obsidian Black, also features bespoke 18 in (46 cm) alloy wheels and specially developed suspension using dampers, a sports spring kit with revised rear anti-roll bar and a ride height lowered by 30 mm (1.2 in) at the front and 10 mm (0.4 in) at the rear.Also standard was a chrome mesh front grille, front lip spoiler, quick shift gearchange, side sill plates and RB320-branded gear knob, carpet mats and exclusive exterior badging. Each owner will also receive an individually numbered black alloy tax disc holder.The Performance Pack (PPP) boosts power to 320 PS (235 kW; 316 hp) at 6,000 rpm and torque to 332 lb⋅ft (450 N⋅m) at 3,700 rpm. This reduces the 0–60 mph (97 km/h) time to 4.8 seconds and the 0–100 mph (62 mph) time to 12.2 seconds.Spec D (2006)A 'discreet' version of the STI was made for a more conservative market. It is similar to the Japanese-spec A-Line except it had a regular WRX spoiler on the boot, silver wheels (not Gold) and no rear roof vane. As standard, it has projector-style fog lights, Smartnav with touch screen operation, Vehicle Tracker, and safe speed system.
A 200W Pioneer DEH-P70BT head unit, adapter and phone connection were also included. The interior featured standard leather trim on the seats and doors, Auto climate control and extra sound insulation. It was limited to a run of 300 cars in only Crystal Grey Metallic so therefore is even rarer than the RB320. Power on this model is rated at 276 bhp (206 kW).
It has a 0–60 mph (97 km/h) time of 5 seconds and a top speed of 155 mph (249 km/h) (electronically limited). New retail price was £28,450. The UK version of the WRX STI GB270 (2007)Subaru produced only 400 cars; 300 4dr saloon versions and 100 5dr hatchback models.
The GB270 was available in either WR Blue Mica (4dr) or Urban Grey Metallic (5dr). The name was derived from the 2.5-liter turbocharged engine which produced 270 PS (199 kW; 266 hp) and 420 N⋅m (310 lb⋅ft) of torque. These upgrades meant a 0-60 mph (97 km/h) time of 4.9 seconds and a top speed of 146 mph (235 km/h).
Saab 9-2X AeroSubaru manufactured a version of the second generation Impreza hatchback, marketed by Saab as the ' Saab 9-2x' (stylized as 9 2X) in the North American market for model years, 2005-2006. At the time, had been a fully owned subsidiary of (GM), and GM held a 20 percent of Subaru's parent company,.Saab redesigned the front- and rear styling to integrate the car with the.
Revisions included modified front fascia, fenders, hood, tailgate and rear fascia. The interior received extra acoustic insulation over the Subaru, with particular attention paid to the, carpeting, roof, and rear window seals. The majority of the interior of the 9-2x is identical to the Impreza wagon. Saab offered a 2-tone seat design based on the earlier second gen Impreza wagon, as well as use the instrument cluster from the earlier second gen Impreza.Saab also specified their own front seats incorporate active head restraints, unlike the fixed headrest seats in the equivalent Impreza WRX. The rear suspension arms are aluminum, with further reduction of achieved by using plastic in place of heavier components, bushings unique to the Saab, and recalibrated dampers. The steering had been made more responsive and exact in the Aero by using the steering rack shared by the STI version of the WRX, which features a faster 15.0:1, more rigidly mounted steering hardware and stiffer chassis bushings. The 9-2X is not particularly popular with Saab brand loyalists for the fact that the changes from the Subaru are mostly cosmetic.
The 9-2X also won the highest IIHS safety awards.In October 2005, however, GM decided that it would sell 8.4 percent of the company to and dispose of its remaining 11.4 percent share back to Fuji in a deal. The 9-2X was discontinued after the 2006 model year with the dissolution of the partnership between Fuji and GM.10,346 Saab 9-2Xs were manufactured during the production run, with 8,514 for 2005 and 1,832 for the 2006 model year. Saab offered the 2005 model year 9-2X with Subaru's naturally aspirated 2.5-liter EJ253 engine in the 'Linear' trim level (165 hp (123 kW) and 166 lb⋅ft (225 N⋅m)), with the turbocharged 2.0-liter engine shared with the Impreza WRX offered in the 'Aero' badged model (227 hp (169 kW) and 217 lb⋅ft (294 N⋅m)).
All-wheel drive came standard with an optional four-speed automatic transmission available instead of the five-speed manual for both trims.For 2005, Saab offered three options packages. The premium package added leather upholstery and for the US model, xenon HID headlamps. When ordered on with the 'Linear' trim, the premium package also included the in-dash six-CD changer, front fog lamps, vinyl door cards, and a leather-wrapped steering wheel and shift knob. The cold weather package added heated front seats, side view mirror defoggers, and front/rear wiper defrosters where the wipers park. In Canada, cars equipped with the cold package also included an engine block heater.
The sport package added a sunroof, and for the 'Aero' only, included 17-inch wheels.2006 model yearUpdates for the 2006 model year included the re-branding of the 'Linear' to '2.5i', with its 2.5-liter engine uprated to 173 hp (129 kW) and 166 lb⋅ft (225 N⋅m). The Aero's 2.0-liter turbocharged engine made way for the higher-displacement 2.5-liter EJ25 turbocharged unit, increasing outputs to 230 hp (172 kW) and 235 lb⋅ft (319 N⋅m). For 2006, the cars had different options packages that essentially broke down the same equipment differently. The premium package became known as the leather package and incorporated the same additions as previously.
The cold weather package also remained unchanged. However, the sport package, with its upgraded 17-inch wheel upgrade package, became exclusive to the Aero as the sunroof became a standalone option.References Wikimedia Commons has media related to.Wikimedia Commons has media related to.
