remember this, the jspec 2jz has a lower stock hp rating than the usdm 2jz. so your starting off with a lower power motor, so you need more upgrades to boost your power levels up. as the jspec 2jz uses ceramic turbos, ditch the twins for a large single and put bigger injectors in. |
To me, a single probably isn't necessary, unless you know your short-term power goal exceeds 400rwhp. Swapping out the intake-side cam is pretty easy. Instead of swapping the injectors (and installing a resistor pack), just put in an adjustable fuel pressure regulator and run a higher base fuel pressure - this should allow the oem japanese-spec 440cc injectors to work just fine for bpu++++. That way you don't need an aftermarket fuel system till you go single.
