Norbie is absolutely right!
And also be careful when it comes to boosting the stock sequential twin turbo setup because high boost can be especially life threatening to the primary turbo. If you want a bit more power than the JDM stock setup, you could potentially source the US spec turbos (slightly larger), but then you might have to tweak the management to suit. Putting in a US spec ECU won't work either because the US spec motors have a MAF setup (not to mention EGR as well as different cam profile/valve lift from JDM) whereas the JDM version has a MAP/TPS system. If it suits you, you can change the sequential twin turbo setup to a simultaneous twin turbo setup (a la 1JZ-GTE) with either electronic or mechanical modification. But that will depend on what you want to achieve with the car. If you want an absolute dyno queen, aftermarket fuel/ignition management, big single turbo (to4r comes to mind), dump pipe, exhaust, bigger injectors, big intercooler and better air intake would be the go. You would see that the internals of the motor is good for well over 600HP (depending on the condition of the motor and how nice you are to it).
Hope this helps...
Cheers
