hey iv not long bought myself a 97 wrx sti import, not very clued up on turbo charged cars. im basicly getting the boost from the turbo at 3500rmp and then at 4500rpm about 4-5 miss fires and all the revs after that the power seems to drop of alot! any ideas? would be really appreciated please!

 

Hello

Lets start with some of the basics first

1. What fuel are you running it on?
2. What modifications does it have?
3. When was it last serviced?

hi tony, im gona seem a bit thick here i feel lol. im running it on high octane(not supermarket) i have zero history with the carso no idea about servicing. the guy that sold it to me said it has a bigger turbo cant remember the make/model, the rest is mostly hks parts air filter, dump valve ect and 5' mongoose exhaust. he did claim it had been remapped for better economy whether this was done first before the mods i dont know? (hope not as that would be a waste of time) oh year i think its a breather hose (top of engine) i found it was snapped half way so thats left open at the mo!
