80LS1T Posted June 22, 2002 Share Posted June 22, 2002 I just bought and LT1 and a T56 tranny and all the extras(ecm, wiring, etc). What I want to know is what do I need to put this in my 1980 280ZX?

Please give me anything that you think is relavent to this question. Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted June 22, 2002 Share Posted June 22, 2002 Welcome ! Guy: Do some research on this site about your planned swap and repost later concerning your questions. Unfortunately Friday is not a good night for beginning conversion ZX posts like yours. Quote Link to comment Share on other sites More sharing options...
labrat Posted June 22, 2002 Share Posted June 22, 2002 What kind of steering setup do you have in that ZX? In my 81, the toughest part is finding an exhaust manifold that will clear the power steering gearbox on the driver's side. If you have the non rack n pinion power steering, you may have trouble with those lt1 manifolds. The best mount I found was for a 69 chevy truck, they are about 6 bux from autozone, have good stiff rubber, and bolt right up to the datsun crossmember. They should work OK with your block. Just put about 3" of spacer on each side (keep adding spacers till the mounting holes line up) between the motor mount and block. I think I used 3" on the driver's side, and 2 1/4 on the passenger side, but YMMV. It was really a lot easier than I expected it to be. I would advise you to buy the JTR manual, but you can't follow it like stereo instructions with this car. It focuses on the earlier models, and we are a little different. If you do a search on my member number, i've tried to document the swap pretty well, as we ZX's are in the minority here... Bill Quote Link to comment Share on other sites More sharing options...
Guest LT-1 350Z Posted June 23, 2002 Share Posted June 23, 2002 lt-1 used the same bolt pattern in the motor mount as regular 350. i think you should go with the kit that msa sell to install a v8 in zx's Quote Link to comment Share on other sites More sharing options...
