I've got a 78 280z. It's had some minor modifications done to it, but didn't fire up. I got it cheap and need to get it going sooner than later. The body is in pretty poor shape and needs some paint and bodywork.
Anyway, I pulled the engine last night and It is a N42 block with an N47 head. From all the running around a searching of forums, I've seemed to either confused myself, or have found contradicting info. What I think I found is that the N47 head has the wrong exhaust ports for a turbo manifold. I realize that the F54/P90 would be ideal, but the N42 block can be turbo'd with the right head.
Question 1: Which head should I located for my N42 block? The compression was at 150 across the board. I planed on replacing the bearings and rings. So while I'm at that point, should I go Flat pistons?
I have all the turbo hardware down as to what I need to locate, aside from the Oil Pump.
Question 2: What do I need to change around Ignition related to make the ECU work? I'm not in a Testing zone so I don't have to worry about any emissions.
