Like the other STI model listed in this article the hardware required is a full Turbo-back exhaust system (as per earlier consider the Track Day variety), a high flow Panel Air Filter such as Cosworth, Green or K&N, a Walbro 255lph Fuel Pump (or equivalent) and an ECU Remap. The Hawkeye STI 2.5 litre model is able to reach around 340-50 bhp thanks to its larger VF43 Turbo and the the modifications listed, with torque in the range of 375lb/ft.

3 Port Boost Solenoid (optional, depending on performance of factory fitted solenoid).

Its worth mentioning here that a full turbo-back exhaust system can become excessively loud and get you РІР‚Вblack flaggedРІР‚в„ў from many tracks, so consider one of the Track Day exhaust systems made by Cobra or Hayward and Scott, such as at the following link these have larger silencers built into the centre section to help keep noise down. As per before youРІР‚в„ўd need to run the car on Shell V-Power fuel or similar 99 Ron fuel to achieve figures quoted. Options over and above this include a Walbro Fuel pump, but weРІР‚в„ўve not seen this to be a necessity at this level.

The upgrade path is near identical to the WRX 2.0 however, with the model requiring a full turbo-back exhaust system, combined with a high flow Panel Air Filter such as K&N or Cosworth and an ECU Remap. Check out our exhaust system pages for this model aty this link Most are produced in 304 grade stainless steel and come with a lifetime warranty. Manufacturers such as Hayward and Scott, Cobra, and Scorpion all produce pipework options for model, with similar prices. If using solely for track use, these can be removed and replaced with stainless steel pipework for a much more free-flowing exhaust system and more power. The car was produced with 3 catalytic converters at the factory and these restrict the power but are required for UK emissions and road use. The WRX 2.0 Models came fitted with a TD04 Turbo charger and whilst being fairly small this is good for around 275-280 bhp on average with supporting mods. There are risks with upgrading the power on any vehicle and the Subarus are no different, so you need to bare in mind that this does put more strain on the engine, drivetrain and other components and as the cars get older and cover more miles the risk it likely greater. The 2001-2005 2 litre UK Subaru Impreza WRX models came out of the factory with 225bhp (for the later blobeye models) and although this makes for a quick car, some hardware and ECU tweaks can release more power for track use.

Finally as per usual before we start, this is a guide only and you should carry out further research prior to commencing work.Р”Р„ brief synopsis of this article is as follow, then read on for more information If upgrading power also consider upgrades to suspension and brakes to support the power upgrade. Please note that this article covers vehicles used on track or off-road and the examples are not legal for road use. This article provides some information regarding tuning upgrades for WRX and STI Bugeye, Blobeye and Hawkeye, 2001-2007, including whatРІР‚в„ўs required and performance expected.
