1982 turbo zx AFM, wire loom and ECU

Hello everyone

I am needing a 1982 280zx turbo AFM, wire loom and ecu. I have a 1975 280z that has an '82 turbo transplant. Problem is that the air to fuel ratio gets lean at higher rpm's. Which is why my pistons are melting and broken:tapemouth. So I figure this may be the best solution, unless someone here has a better idea with what I have to work with.

Note, I have not look hard into mega squirt yet. but lets start here first.

Thanks.

Big Al.
