I just made a verbel(or email agreement rather) on a '77 280Z for $400 but the motor has a bad bearing. Heres the good part I have a '83ZXT parts car sitting in my yard. The wiring harness is there but it has some badly frayed wires and several missing and cut ones plus its been sitting in the elements for a few years with no windsheild so the ECU is probably shot. I wanna use the turbo block and head with '77 NA ECU and harness.

I need the bigger turbo injectors and AFM for sure right? what else? Probably need to use the NA distributer cause if I'm not mistaken the turbo one runs off the ECU. Fuel pump maybe?

My next question is could a person who has not done this kind stuff before ge it done right? I've done engine swaps before(once in a 84 cavalier, and several timees with a '64 ford falcon) but never messed with FI.

Thanks for any help I need all I can get.

I suggest you to get that turbo car run good first before attempting to do the engine swap.. Otherwise you will be wasting your time.. If your turbo car runs good then swap everything from that car into your Z.. Good luck

I bought it off of my uncle summer '99 along with my 80 280ZX, I didnt know anythihng about it. Since then I' ve robbed countless parts and used it to practice on before I attempeted to do it on mine so its pretty ragged. Heres the crappy part the other day when he was here he told me it ran like a top, the only reason he stoped driving it was because the waterpump and starter went out on it. So I basicly screwed up a pretty good car.

If the turbo engine is goodthen you shouldn't have any probs. I would swap the 77 intake(or an earlier75 intake without the EGR valve) onto the turbo motor. This way all your cold start stuff will work. You will need to put the turbo throttle body on it to get the tube from the turbo to bolt up. Use the turbo injectors on the 77 rail( for the cold start valve). You will also need to swapp out the guts from your AFM to the turbo AFM. Use the 77 distributer or a stand alone one from a 280zx. You will need to swapp the distr. shaft out from the turbo car and put a reguklar one in to run a NA distr. I think that's about it. The idea is that the ECU will run rich due to the bigger injectors, but runs lean because of the larger AFM. They basically balance out. You will probably need to adjust the AFM, but it will work. Email me if you have any other Qs.

Thanks alot you have pretty much answered all my questions your are the man!

Let me get this straight, use the '77 intake, dis., and fuelrail, turbo TB, turbo injectors, and turbo AFM w/ NA guts. That sounds easy enough, I guess the hard part will be the engine swap its self.


Thanks alot!
