No way I've asked the GT4 has some chassis differences the GT-R, besides I just put a deposit down on one so yh. I love the 2JZ sound, it's one of the few I6s that sound deep and mean. It also has larger capacity potential and the power figures they make are amazing. I know of that build on Tremek, I know it's been done. I wanna know how much and what it would take, who would do it and most importantly keeping the 4WD Otherwise I'd just drop an LS3 in there (which I would never do to a GT-R). If the build is too hard and costly I'll just get Robbie Ward from RIPS NZ to build me a stroker RB30. That company really seems to know it's craft. Just check their vids on YouTube, no one builds better RB30s.
