Hello, I know this topic has been absolutely beaten to death, but after 2 days I can't find what I am looking for. I have a 76 280z. And I am going to either turbo it, or to a turbo engine swap. What I can't seem to find, is a straight answer as to the actual differences of the l28e and the turbo model. I have seen posts ranging from dont turbo the na l28e, it won't run well at all, to it Runs great with no problem pushing 15psi
From what I have found, the afm, ecu, distributor, cam, oil pump and injectors are the major things different.
My goal is 250-300hp at the wheels, running a max of 15psi. I just am not sure what corse to take, I understand the turbo has a little lower compression. But with a metal head gasket, head studs, and some 440 injectors, I don't see an issue running the n47/n42 combination. I like the higher compression, and the bigger valves on the na head.
My unanswered questions are, first, what do you guys think about what I have said above?
And are the rods different between the turbo and the na, and how much power can the stock bottom end handle?
Once again, sorry to bring this up again, just can't seem to find what I am looking for.
