but, honest, your engine is already fast, cos i know what's in the engine.. hehehe.
only thing you need is bigger cc.. ie 3.0 or 3.2..

your cams are equal to the USM3B30 spec, only yours is none vanos, your ecu is either 402 or 403, one of it is Jap spec ecu. Not many tuner's have 402 mod's on the ecu to play with it(the 402 ecu map is very limited, due the 413 is more better to tune) btw, 413 is vanos ecu.
