Garrett GT2560R-JP x 2, 400-475 PS each
I highly recommend to put "at least" forged pistons in there.
I spec the engine always higher than turbines.
I just put in a R34 Nur engine in my car with Tomei 1.0mm headgasket.
I'm breaking in my engine now... taking sooooo long to break-in the engine.
anyways, Good luck on your rebuild!!
