ONARUN:
yeah get a price from BD4's and post it here. The price i got was from the guy who complianced my car in melbourne. He gets parts striaght from Japan, even HKS themselves!!
I think that with a 2540 and only at 1bar you should be getting 220rwkw. Matt (whatsisname) from SDU forums only runs about 12-13psi and has 220rwkw if i remember correctly, with a T3/T4 turbo
Ive also replied to your PM onarun.
