Ok, I'm new here and I am swapping an LS1 into a 300zx and was wondering if anyone on here has done it or knnows anything about it. Do you need to do any firewall customizing? Also what about the transmission, anything to do to get 4l60e to fit? Wiring harness? And last best conversion kit? I would also like to keep this as stock looking as possible I have looked and looked an cannot find anything and the stuff I do find does not explain anything at all. Thanks in advance.
