iv got an MY95 WRX which was last rolling roaded at 276bhp@flywheel with exhaust, downpipe, decat.

Iv only owned it a couple of weeks, but it has a crappy slanty intercooler on it, and a K&N that looks like its 10 years old which i imagine arent doing it any favours!

Iv got an sti5 intercooler sat here waiting to go as well as a standard airbox, and an sti panel filter is on order from stiracing. I was also thinking of an uprated fuel pump, and a remap.

just out of interest, would you imagine that this lot would see it over 300bhp?

 

no would be the simple answer, but you cant draw figures out of the air like that.
look into the projects section for Carl Davey's 300 quest.
a spec list a lot bigger than yours and he fell short, with a bit of fettling he made the numbers.
look at Bobs quest for similar power.
At current pricing it seems to take 2 grand to get 300 brake

 

i got 317 bhp at prosport running 19 psi - wasnt healthy for it, bad detting - bigger injectors required and apexi power fc on the way next!

the current engine spec thow:
scooby ecu @ 15.5psi on optimax (Z4 ecu) (used HKS FCD & manual boost for above r.road)
HKS induction kit (custom heat shield and cold air feed)
hks downpipe
scoobyworld centre & afterburner angled backbox
new coil packs & NGKpfr7bs
full samco's
walbro fuel pump

So anyones guess as the power - i would guess at 280/290 if im lucky
on above mods and that lot cost a fortune and only scratching the top of mods!!!
