I need to make sure this is right..
 

The N/A motor that is in my car now is missing coolant and pooring out oil... I am thinking head gasket, but dont have time to check.. Am I correct in assuming I can bolt all of my N/A manifolds and wiring up to the P90 head?? Also would the distributor work on there as wel?? I am in a tight spot because this is my only mode of transportation, and I need this car for work. And my SDS system is not comig until the last week of june. thx in advance.

The intake should bolt up, but it's got different vacuum fittings and what not. I'm not sure about the exhaust, if it's got the same type of exhaust ports (?) it should fit as well.

I'm not even going to take a stab at the distributor though. I'm sure someone else will help you there.

Good luck

The distributor stays in the front cover. That does not effect your head swap.
Your NA 280ZX if it has a stock head will have round exhaust ports. You should not put on a round port manifold on a square port head.
Get a 1975-76 exhaust manifold to slap on the P90 head. Maybe cheap in a junk yard.

Thanks for all the info. I got ahead of my self, I some how blew the oilpan gasket oh what a relief I hate rushing things, and an turbo engine swap is not something I want to rush.. :D Thanks again
