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

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 ?
