What mods for 400/400?
MY03 STi PPP - what would I need to do to get 400bhp/400+lbft (without losing driveability/reliability)?
Cheers Steve :thumb: |
Have a search for the MD321H turbo, I think I spelt it right but seems to get very good write ups and produces just over 400bhp.

Steve, This lot will get you the power that you are after (400+ bhp) but a little shy on torque. I have this fitted to my 03 Sti along with 650cc injectors and an Aquamist system and it is averaging around 415bhp and 375 lf/lb on the rollors. No reliability issues but there is always an increased risk of failures when you start going up the power ladder. The car is very easy to drive around town, a bit too easy, even the woman takes it out and about :( |
I would think you need a new turbo like the md321h already mentioned,fmic,manifold and re-map

3" Decat, MD321H/TD05 20g, Headers, Plugs, Induction, Remap
You could keep a smaller turbo and use additives, like NF or methanol. (* With that power, definitely be needing money for brakes & suspension). Probably budget for around £7-8k. No need for FMIC, unless really ragging/track work. If that's the case, then set the mileage counter to zero and see how many miles you get before something blows. Engine is outputting 150%!! Clutch has no problems, but i'm gentle with the car anyway. 392/361. :) Spools quicker than standard. :norty: |
