I HAVE A 83 TURBO ENGINE ECU & AFM, BUT I DON'T HAVE THE WIRING FOR THEM I HAVE FOUND A 82ZXT IN A JUNK YARD THAT HAS ALL IT WIRING WILL IT WORK WITH THE 83ZXT MOTOR. THE ENGINE I HAVE CAME OUT OF AND AUTO, AND THE ONE IN THE JUNK IS A 5 SPEED..
The wiring is compatable. The '81 turbo has the crank angle sensor on the harmonic balancer where the '82' and the '83 have it built into the distributor. The only other difference I can think of is whether or not it is an automatic or manual tranny and I don't think that matters (I'm using an "automatic" system on my standard tranny Z)
I agree with Retro that it there is no significant difference between auto and manual wiring on the engine. One glitch you MIGHT run into is if the '83 had a digital dash. I don't know for sure if sensors on the engine were diffrent (oil pressure, temp, etc.), but from what I've gathered on other posts, they might be.
