Heya guys,
I'm new to z cars, I'm a muscle guy. But I've always had a thing for nissan z cars and the other day I picked up a 85 NA z31 with ~140k miles for 700 bucks.
The transmission is in good shape the clutch is ok for now and the engine runs, but with what seems to be a bit of a misfire. and theres a terrible exhaust leak.
My question is, to make decent power would i be better off:
a. Rebuilding the VG30E and turboing it. or
b. Buying an RB25DET and swapping it in? (paying a shop to do swap since i'm pretty much lost in the world of imports lol)
any info on which is better for power, which is cheaper, or just prices in general would be helpful.
