I enjoy watching this RoadKill program. They got a 240z on the cheap and put a built 4.3 in it with S-10 five speed trans. They felt it needed more power and then turbo-ed it. https://www.youtube.com/watch?v=WcjC00J8FaM
I can trade one of my conquest for your 1jz swap pile. I have three right now, one running. Do you want an auto or a 5 speed mostly stock or heavily modified.
