Morning peeps, currently my v4 Sti is running an induction filter, turbo back cat-less exhaust and I have a walbro fuel pump I have to fit. I'm considering getting it remapped soon and would hazard a guess at around 320bhp. If i were to hold off a little while and attempt to push towards 350-370 what other supporting mods would be required? I'm guessing at least injectors but which ones etc, thanks

Is your ecu remapable?
You may need a clutch

i don't know any reason why it wouldn't be mappable via ecuteck or ESL?

So in addition to what I have I'll need 550cc injectors, a fuel pressure regulator, turbo and new age top mount intercooler, I definatkey don't wanna go front mount and chop the bumper up as think it will spoil it.

How much power will the Vf24 goto? Which turbos are a recommended upgrade that arnt going to be laggy?

Thanks

Is it a JECS or denso ecu? Only denso can be remapped.
As above you are looking at a 20g or SC 36/ SC38 for that power. VF43 maybe?
VF24 is 330hp turbo I think not big enough.
Be the best part of £2000 to get to 370bhp if you fit the parts yourself.

Ah I didn't know that, I'll have a look under the kick panel and check it out, if nees be ill have to save up and go simtek lol

I think I'll stick with what I've got, get the mapping done and see what we get, drive it and see if I need more after that lol

Thanks for your help
