Subaru impreza sti 400bhp

Description:

2003 (52 plate) Bugeye Subaru Impreza WRX STI. It's currently running 400bhp and 400lbs torque and it has had the best of everything on it in terms of parts. I'm wanting to buy something that doesn't cost quite so much to run and maintain. I built the engine myself (I'm a mechanic with lots of experience in Subaru's including engine work).


The spec is as follows:


SCD 2.5 block

Mahle pistons

RCM conrods

Cosworth race bearings

Cosworth 11mm head studs

Cosworth head gaskets

New valves and seats

Uprated 11mm Subaru oil pump

Subaru water pump

RCM/Gates timing belt kit

Subaru gasket and seal kit


Of course the blocks and heads have been machined too.


The engine as it is will handle a safe 450bhp. I chose not to have it pinned or close decked as I have read about many failures, it's pretty hit and miss when you do this and I wanted a reliable car. When I built the engine I thought 450bhp and 450lbs of torque is plenty for the road (I'm sat at 400 now and you have to be awake for that lol).


The cars mileage is 102k and the engine has around 8k. I think it has had 6 owners but not sure. 3 of those has been my family.


Other modifications are:


SC42 turbo

Hyperflow fmic

Hyperflow inner wing induction kit

650cc injectors

Fuelab fuel pressure regulator

Walbro 255lph fuel pump

Scoobyclinic silicone intake pipe

Apexi AVCR boost controller

Apexi 3-port boost solenoid

HKS dump valve (can be used with or without)

Exeedy Organic Clutch (can't remember the max torque rating but it's way past the 450lbs I'd planned it for)

RCM GT spec headers

Turbo-back Milltek 3" exhaust system
