Hi guys. I have an 03 STI with PPP pushing 300 hp. I wish to join the 400 club. How would I do this and how much would it cost?

 

turbo needs to be bigger, need good map and lots of v power. id give lateral performance a ring, and have bob rawle or simon at JGM map it. prob need a fmic and ecu board - alcatek are good. 2 maps als and lc and there new boards offer more to now they have updated it. if your in redditch id try thwaites in warwick, mark will give u some good pointers.

 

I think the STi tmic and ecu are up to the job for 400bhp. The standard injectors if there 562cc should also be ok. May need an uprated fuel pump, bigger turbo and map .

 

I have md t turbo
650 injectors
full 3" exhaust
gt spec headers h/s uppipe
hrc fuel pump
silicone inlet hose
ks tech mega maf induction kit
fmic
running 430 mark on standard clutch waiting for it to go :-)

 

Thanks for the replies. Guess I'd better start saving.
