1976 280z
I have a 1976 280z and I am wanting to turbo it, but I need advice. It has 180k miles on it, what internals do I need to replace before I ---- with a turbo.
As for as the engine goes, I was going to replace the cam, valve springs and retainers, rods, pistons, rocker arms, valves and get new head gaskets.
Is there anything else I should do before I turbo?

Re:1976 280z
Due to the age of the engine, I would go ahead and do a rebuild.. Just freshen it up. I dont know what the factory compression ratio of that engine is, But I would build something around a 8.5 to 9.0c/r engine. Not to high, and not to low.
Now correct me if I'm wrong, but Wasnt their a few years on the 280's that came with factory turbo chargers? Are the manifolds interchangable from the NA to FI versions of the engine?
I am actually a Nissan Tech, But I have very little knowledge about the older Z's.
I would assume the rods are pretty strong, I have yet to see a Nissan with small rods, other than the QR25.

The 350 motor/trans is a direct swap. Just gotta get the motor mount kit from JTR, its like $340. The 350 motor adds a lot of weight to the front of the car and makes it handle like ----. A lot of people will not do the swap simply because it will rip the car apart.

I figured I would get an aftermarket exhaust manifold (or header, whatever) and have that raped and made to support a turbo application.
