| I can tell you that .4L of displacement is a big issue. Seeing lots of Supra's Going from 3L to 3.4L is a big change on a 90mm turbo it was worth 1000RPMS of less lag.. Anyways think Grand National they for being domestic were in many ways years ahead of us. Turbo placement, heads, blocks, cranks, all made new. I really come the conclusion that best engine for a street power goal for +600RWHP is a 4L V8. 3L is to small 2L engines are still way to small. The 350Z with the 4.3L Stroker motor is awesome as well. I have considered putting a AEBS 4.3L VQ35 with 6 Speed Getrag transmission, and a Nice new Ball bearing 76mm turbo. Then again my ideal car now is a TT-Galarado :-) Still love my 300ZX tho.
