S500BE

hi chaps i have an 03 sti ppp with full decat k&n typdoon induction kit and a remap was currently getting 347 bhp just fitted a tdo5 18g and now its about 357 bhp so not much improvement am i missing something or do i need more mods or different turbo? i am aiming for the 380-400 mark
thanks

imo for 380 you`d need the td05 20g as a minimum. What fuel pump and injectors is it running? Also, has it got an uprated boost solenoid? i`d also say either an uprated tmic or a fmic too

by the way, if its got a full decat and its had a remap, is it really a PPP car anymore?

Did you get the car remapped after the TD05 18G?

As already stated, If you want 380-400bhp on SUL then the 20G would be the turbo of choice. Ported and wrapped headers a good idea as is a 3 port boost solenoid. Personally I'd ditch the induction kit too, not really necessary unless you're running an FMIC

yeah it was remapped after fitting

fuel pump is that not uprated with the ppp kit?
standard sti injectors
no uprated boost solenoid either

i was told the 20g would give me too much lag!!

Bigger turbo = more powerm but more lag mate!

If you can afford it, the MD321H turbo will give you 400bhp potential responsiveness similar to a VF28. Will cost you though!

I'd probably be grateful for what you've got. That power figure isn't shabby and it will make for a quick and responsive road car

where you get the 18g from? have you not had the headers ported and wrapped or gt spec 2 headers?

for a 20g look at view my scooby as i have that on mine not too bad figure wise and not as bad as people think lag wise
