55-819: In 1988, FHI created Subaru Tecnica International (STi) as a its motorsport division to develop and compete in the FIA World Rally Championship and other motorsports activities. Following the introduction of the first generation Impreza in Nov. 1992 and the following year's debut of the Group A rally car into the WRC, an 'STi version' was made commercially available in Jan. 1994 as a homologation model under FIA regulations. Thereafter, subsequent evolutions dubbed STi Version or simply STI were manufactured and sold alongside

110-457: A VF23 IHI ball bearing turbocharger while the JDM non-STI gets a VF22. Power remained at 280 PS but torque was raised from 253 lbs./ft of torque to 260. Forged pistons were also added. The interior and the cockpit were changed into a newer design along with the new "White color" gauges. (white faced) The power stayed the same as the previous version 280 PS. The engine layout and design

165-520: A facility at the former RAF Honiley airfield and LucasVarity proving ground near Wroxall, Warwickshire , together with Marcos and TRW . In March 2006, Prodrive announced its intent to build a £200million, 200-acre (0.8 km ) motorsport facility called "The Fulcrum". As of 3 August 2006, Prodrive has won the support of the Warwick District Council planning committee for development of The Fulcrum. The permission covers

220-626: A highly advanced engineering research and development campus, a conference facility called the Catalyst Centre and new access road, a roundabout, infrastructure, parking and landscaping. The plans still have to be presented and agreed by the British government's Department for Communities and Local Government . There is local opposition against Prodrive's plans via the Fulcrum Prodrive Action Group (FPAG) to protect

275-557: A highly desirable variant. 16 of the 'export' 22Bs (see above) were modified by Prodrive , with longer gear ratios, UK specification lights and an official 3 year warranty. Because 50 22Bs had already been imported privately into the UK, Subaru UK had to wait until 1999 to register the 22B Type UKs under the VCA's Single Vehicle Approval scheme. The price was £39,950, approximately the same price that grey import 22Bs were being sold for. To counter

330-516: A more angular look when seen from the side. The foglight covers had pink STi lettering. Not much else besides minor suspension improvements and a small increase in torque output was 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 and body panels . The Spec C's handling was much improved due to an increase in caster (from 3.5 degrees to 5 degrees). This

385-561: A quite distinct exterior design difference, the Impreza WRX and WRX STi version had mainly mechanical modifications. One way to identify the version is through the VIN plate on the chassis. Sedan and Coupé STi model codes are named GC8, (USDM coupés have a separate chassis code of "GM") and Station Wagons are named GF8, followed by a letter from A to G. A GC chassis version of the RS was released for

440-657: A radio and air-conditioning in the V-limited form. 1000 WRX STi Version 2 V-limited were produced. 555 (the cigarette brand that was the premier sponsor of the Subaru World Rally Team and became synonymous with the Impreza WRC livery) WRX Type RA STi Version 2 V-limited were produced. It developed about 300PS but output was reported at the then-established gentlemen's agreement power limit of 280 PS (210 kW; 276 hp). Torque peaked at 4000 rpm with

495-564: A street legal road car. The second is a complete car pre-fitted from the factory with parts that are available from the STI catalogue and marketed as a 'Tuned by STI' model. Spin-off models with mainly cosmetic additions or alterations are also marketed usually in limited quantities. The first generation STI tuned road going cars were only developed and sold in the Japanese market. Although marketed by numerical version indicators up to 'Version VI' in

550-477: A unique hood, front and rear fenders, a WRC-inspired front bumper and a unique adjustable rear wing. The origin of the name 22B has often been debated. Many assume 22 referred to the 2.2 liter displacement, and the B was for the boxer engine or the Bilstein suspension. This would correlate with the idea that Subaru sells a Legacy Spec B, which also has a boxer engine and Bilstein suspension. Others believe that 22B

605-592: A value of 35.0 kgf·m (343 N·m, 253 ft·lbs). In standard form, this version has a top speed of over 240 km/h. The car gained 10 more kilograms and weighed at 1,250 kg (2,756 lb). The STi shared the same face lift that the rest of the Impreza line received. With Version III came the start of the coupé version of the WRX STi. It is called the WRX Type R STi. The coupé was chosen by Prodrive for use in

825-474: Is capable of a 12.8 second quarter mile. The 22B, which carries an additional 20 N M of torque, has been timed at 12.5 seconds, however AWD cars can be difficult to launch, due to potentially bogging down if engine speed is too low, or the clutch is not correctly taken up. This car was given a unique color of blue and had fender flared widebody taken from the Peter Stevens designed WRC car, thus widening

880-407: Is mechanically similar to the previous revision. Changes include a different turbocharger VF43 equipped with a slightly larger wastegate port to prevent boost creep (VF43, as opposed to VF39 in the older version) and revised gearing on the 6 speed manual transmission. They also use top feed injectors instead of side feed injectors like the previous STi models(04-06USDM). This means the intake manifold

935-457: The Arai tuned dampers and a 21 mm (0.8 in) swaybar . The rear suspension is changed from rubber bushings to pillowball bushings. The strut tower 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

990-611: The Aston Martin Racing brand. On 29 May 2009, it was reported that Prodrive had submitted a formal application for the 2010 season. However, Prodrive was not accepted to the final grid. Prodrive was one of two potential buyers considered by the Renault F1 Team to take-over the team prior to the 2010 season . In April 2010 Prodrive announced it would not apply for the 2011 Formula One season. The slot became available after US F1 Team collapsed. Prodrive had

1045-611: The EJ207 , however the engines did gain Variable Valve Timing (AVCS) further improving their low end torque production. The interior was updated with a STi logo on the gauge. The STi's tachometer also has a red shift light. The STi's and optioned Type RA STi have received Brembo 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,

1100-449: The FIA announced the list of entrants to the 2008 Formula One World Championship . It was announced on 23 November 2007 that Prodrive F1 would not compete in the 2008 , as the legal situation left no time for the team to be set up for the start of the season. On 23 April 2009, Prodrive issued a press release stating that they were considering an F1 entry for the 2010 season, possibly under

1155-633: The 16 22B Type UK below, along with another 5 for Australia, and 3 prototypes. The 22B had the EJ22 engine as opposed to the regular EJ20 engine. (Note internal Subaru material states the block comes from a V3 EJ20G, not the EJ22G as most think. Also the intake manifold and heads were from the V4 EJ20K) This means the displacement was increased from 1994 cc to 2212 cc. The block is a closed-deck design. The heads (valves, valvetrain and such) were lifted from

1210-600: The 2004 debut. The oil pickup line inside the oil pan was shown to develop a crack leading to oil starvation and engine damage due to the lack of lubrication when the part fails. Several aftermarket vendors have addressed this issue by re-designing factory oil pickup units with more substantial welds and materials. 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

1265-592: The Impreza model lineup initially in Japan only and later in selected world markets. As the STi or STI model was typically the highest spec of the Impreza, it has become popular with performance enthusiasts, tuners and amateur racers in many motorsports disciplines especially rallying and circuit driving. Used STI cars usually command a higher resale value and continue to be highly sought after. FHI has released many different models and versions including special limited editions of

1320-472: The STi Version 4 engine. It produce 280 PS (210 kW; 280 hp) at 6000 rpm and 363 N·m (267 ft·lbf, 37.0 kgf·m) of torque at a lower engine speed of 3200 rpm. The redline is 8000 rpm. The compression is an 8.0:1. The turbocharger is an IHI RHF 5HB (the internal company usage code is VF23, although a number of the cars received the larger VF22). In performance terms, the donor STi Version 4

1375-566: The STis had larger hood scoops and had foglight covers with STi embossed on them. The DCCD was updated so it can work with anti-lock brakes . During braking, when the ABS 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

1430-480: The USDM in 2001. To tell the difference between a JDM Sedan and Coupe chassis from the applied model code only, a sedan will have the fifth digit as a 4, representing 4-doors, and a coupé will have a 2, representing 2-doors. The first STi was known simply as WRX STi (there was no "version" moniker added to the name until the version II). 100 Imprezas per month were produced starting from February 1994. In March, production

1485-486: The WRC because it was lighter and stiffer than the 4-door version, although it carried the same exterior dimensions. It was essentially a 2-door version of the WRX Type RA STi meaning it had DCCD, minimal sound insulation, close-gear ratios and hardened gearbox. This car also has a water-spray nozzle to dampen the top of the intercooler. The water will then evaporate, taking heat away from the intercooler and cooling

1540-538: The WRX STI. However many of these versions were and are only available in the Japanese Domestic Market. Although the concept behind the STI model is taking a base model such as the Impreza or Legacy and further developing it for high performance, STI models fall mainly into 2 categories. The first is a fully developed and tested model with the purpose of homologating it for motorsports which is sold as

1595-432: The WRX STi received the aforementioned updates. The WRX Type RA STi was produced. The STi wagon was still produced but its engine only produced 275 PS (202 kW; 271 bhp) . The STi foglight covers had white STi lettering on them. The WRX Type RA STi was used for the Group N homologation. Along with the rest of the Impreza line, the grille and body of the WRX STi was minorly updated by Peter Stevens to give it

1650-458: The WRX came with a Driver Controlled Center Differential (DCCD). This device was an electromechanical differential that could lock the differential. The DCCD would be beneficial to people who used it in various rally conditions. The regular STi's engine output stood at 275 PS (202 kW; 271 bhp) and 32.5 kgf·m (319 N·m, 235 ft·lbs) of torque. This was the year that STi started painting

1705-516: The assembly line and replaced by STi parts. After this version, the standard STi was built alongside the WRX on the production lines. The WRX STi Type RA (marketing has made usage of the RA acronym in various ways; Record Attempt is the current usage. "R = Racing, A = Group A, FIA the racing class the WRC Impreza competes in" has also been confirmed by Subaru of Japan; the correspondence can be seen on

The car is fitted with 235/40 ZR17 Pirelli P Zeros. The clutch was upgraded to a sintered twin clutch with a ceramic disk. The transmission ratios are the same as the standard WRX Type R, but the gears were shot-peened for added reliability. The car has

1815-509: 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. The WRX STI Spec C was used for Group N homologation. The WRX STI Spec C Type RA was released in November 2005, with 350 units produced. The Type RA added

1870-522: The catalogue, there were in reality more than 20 different possible types of Impreza STI cars for sale. Many of these were in different body styles and some designed as a base for motorsports use. Others, such as the 22B were special limited versions but had different specifications. Visually it is hard to tell the difference between versions or the non-STI Impreza WRX. Unlike its rival car the Mitsubishi Lancer Evolution, which sported

It had a tri-planar wing and a massive front airsplitter. The entire suspension was composed of STi parts. There were 300 S201s produced, they used a VF28 spec turbo, with max boost at 1.2 BAR and produced 224 kW (305 PS) and 353 Nm, weighing in at 1270 kg these are

2090-625: The grey imports of high-performance Japanese variants, Subaru UK commissioned Prodrive to produce an 'official' limited edition of 1,000 two-door cars in Sonic Blue. The chassis was a 2-door coupé. They were taken from the STI Type R lines and used for the P1. The car was the only coupé version of the WRX STI GC chassis to receive ABS. In order to allow for ABS, the DCCD was dropped. Engine output

2145-415: The increased wheel width, steering lock-to-lock turns have been reduced. Wheel hub strength was improved. The P.C.D. was changed from 5 x 100 mm to 5 x 114.3 mm. The interior was vastly improved as well. A whole new center console now brings out a very high grade interior feel. The WRX STI continues on relatively the same. The Impreza line's looks have been updated. The WRX STI Spec C's receives

2200-606: The intake charge. This car was produced on an order-only basis. Also, there was a WRX STI type RA (4-door) available in Version III. These have the same motor, gearbox and R180 diff as the Version III WRX STI Type R, including DCCD, aluminium bonnet and front guards, no sound deadening and thinner glass. The ECU is also an exclusive tune. The Type R tends to be a bit stiffer and weighs 1,190 kg (2,620 lb). The DCCD has been known to bite new drivers in

2255-490: The intake manifold red. The car weighed 1,240 kg (2,734 lb) and had gold wheels like those on the World Rally Championship Impreza. The V-limited STi edition was produced. It was a limited edition that was often used to celebrate a Manufacturer or Driver title award to Subaru's World Rally Team. The interior is colored blue on the seat inserts and carpeting. The WRX Type RA STi received

2310-406: The regular WRX had an 'A'). The fourth character of the VIN gives the revision (A to F where G is the 2007 version). For quick and easy reference to the different exteriors, Subaru Impreza owners use nicknames based on the headlights. Often relating to a creature that has similar looking eyes: 2001–2003 are 'bug eyes' / 2004–2005 are 'peanut eye', or 'blob eyes'/ 2006–2007 are 'hawk eyes'. In 2000,

2365-489: The third being used by Subaru Japan as their press car. It was widely rumored David Lapworth of Prodrive owned the third #000 car, however he actually owned #400. Subaru Tecnica International started the S-series of special Imprezas. This series is a limited production series that sports an engine output of greater than 280 PS (210 kW; 280 hp) [had 224 kW (305 PS)] (special variant cars were excluded from

2420-426: The wet. The RA gets a roof vent instead of map lights, and wind up windows, although electrics are an option from factory. Also available was a WRX Type R V-limited, in version III. It has a WRX motor with no forged internals like the STI, and it misses out on the 4 pot front brakes as they are to be installed by rally teams. It has a roof vent and is lightweight, making a good base for a rally car. Version III STI runs

2475-414: The width by 80 mm (3.15 inches) for a total of 1,770 mm (69.7). During assembly, a WRX Type R chassis was taken off the line. The fenders were replaced with the 22B STi fenders. The car's curb weight is 1,270 kg (2,800 lb). The suspension is provided by Bilstein. The brakes were Brembo manufactured standard 4-piston/2-piston brakes. However, the color is red and the Subaru name cast on

2530-436: Was achieved not by changing the suspension mounting point, but by lengthening the wheelbase (15 mm). This was done by including different control arms . 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 oil cooler . The WRX STi wagon had ceased to be produced. Little change from Rev. B. The WRX STi

2585-441: Was also produced as a 555 limited edition. Most of the changes were cosmetic. The wing was sculpted to be more aggressive. VF28 spec turbo with max boost at 1.2 BAR and produced 224 kW (305 PS) and 388 Nm. There were 2000 WRX STi Version 6 Limited, 500 WRX STI Type R coupe Version 6 Limited and 2000 WRX STi RA Version 6 Limited cars produced. Also 500 WRX STi Version 6 Limited Hatchback models. In 1998, Subaru of Japan produced

Options were available from Subaru consisting of 4 piston front brake calipers, electric Recaro seats, 18" OZ alloys and a P1(Prodrive) stamped backbox. The P1, or Prodrive One, is echoed in the name of the Prodrive P2 concept car. In 2000, the Impreza line received a complete update. The chassis

2695-545: Was made cleaner and was dubbed as the Boxer Phase 2 engine. The facelift the rest of the Impreza line had was also applied to the STi. The WRX STi weighed 1,270 kg (2,800 lb). There were 1000 WRX Type RA STi Version 5 Limited cars and the WRX Type R STi Version 5 Limited cars had a 4 month waiting period for each order. The interior was also changed slightly from the Version 4 including seats and steering.This model

2750-548: Was meant to represent the 555 cigarette brand was a major sponsor for Subaru in the WRC, as 22B is a hexadecimal representation of the decimal number 555. The 22B STi that is supposed to be #13 was never given the plaque. Subaru of America imported #13 to be used as a press car. Three prototype 22B STis were given the #000 plaque, 2 went to the World Rally car drivers for Subaru at the time Colin McRae and Nicky Grist , with

2805-530: Was sold in the US without a radio or floormats. The car was rated at 300 bhp and 300 lbs-ft torque, although many feel it was under-rated on purpose. What made the car so special to most is the level of performance offered for a mid 30 thousand dollars car, that still has a back seat and a big trunk. Since its launch, many upgrades became available to increase power, handling and braking capabilities. Some weak links were discovered in most 2004–2007 models since

This version of the STi was the only version where the standard cars were taken at the end of

2915-402: Was stiffened so that it had 120% torsional stiffness increase. The WRX STi gained 17" x 7.5" alloy wheels over the previous 16" x 7" wheels. The 5 speed manual transmission (reputed to be one of the car's weak points) was changed to an STi engineered 6 speed manual transmission . The engine was retained from the Version 6 STi and still retains the semi-closed deck block and is still labeled as

2970-626: Was used for Group N homologation . This was the first Impreza STi model to be offered in the United States. Subaru unveiled this model in 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. The 2004 WRX STi is considered to be the lightest (3263 lbs, official brochure and tested by Car & Driver Magazine) and rawest among 2004–2009 models. The car
