L28et Motor swap into 77 280z 4 speed, ofcourse with problems

Hey did you ever find out your problem. Reason why I ask is because I'm doing the very same thing. I just need a turbo exaust manifold and i can drop in my engine. Are you. Running the correct ecu for this engine. I'm dropping in a 82 zx turbo moter in my 77, check put mine on here. Also can you use a 82 non turbo transmission and my non turbo 77 clutch with this moter?

Sorry I haven't been on here in a while.

Didn't figure out the idling problem. It runs at about 700-800 rpm during initial start, then falls on its face after about 2 minutes. I'm thinking the computer and a vacuum leak are causing terrible idle. I definitely had an exhaust leak off the manifold to turbo connection (hence the tractor like sound; fixed that issue)

What do you mean by Oil Pump Position? Its immobile but the Motor  is very intermitant with the Bad Running problem

oil pump position? Timing?
