max power on standard internals
 

what is the most power the standard internals can take on a 2002 wrx.What level does the fueling run out?regards rollers

No more than 320bhp if u wanna keep the standard internals..

I have been running circa 350bhp for the last year quite happily. Currently at 368bhp.

Make an uprated fuel pump one of your first mods. Mine was fitted at 250bhp.

Good luck

Ninnybobs....thats on a wrx?? if so very impressive.

The gearbox will go before the internals, i ran 382bhp for a while!

John Banks had over 400 bhp on a MY00...

Neilo,

It is indeed an MY01 WRX

440 bhp is not a problem on std internals on a 95WRX if properly set up :)

even with cast pistons andy ?

but the question was for a new age wrx :p ;)

OK David, 419 is the highest with cast pistons on an old wrx and 416 on a phase 2 engine but with a bit of octane in there, I'm sure the guys could have also made 440 without them failing.
No reason why an 02 shouldnt be capable of the same, is there ?
