What engines will fit a '86 300zx?

My stock, non-turbo 1986 300zx just blew a rod and I was wondering what options I had for looking for a new engine, or if it would even be worth the money. Thank you for any help you can offer.

I've thought about snatching up a low mileage VG from a pathfinder, pickup, maxima, 200sx SE, quest(also mercury villager), maybe there's one more I'm forgetting too, but anyways, you will have to do some swapping of alot of parts from the old engine to the "new" one to make this work right with the Z, here's a write-up somebody did when they used a maxima engine- http://z31.com/repairs/newengine.shtml

I would use a vg33e out of a 96-00 pathfinder or 99-04 frontier, or 00-04 xterra. I don't think the intake manifold will work from the trucks, but I bet you can put the 300zx one on and make it work with the newer computer. Heck might even work with the stock computer. Having 300 cc's more of displacement can't hurt.

You could keep the pathfinder intake manifold for some good power (it is a gtood mod for a normal VG30E or ET). Only problem is the hood won't fit right.
Stick with the VG30E from an 84-89 Z31 or get a VG30ET or a VG33ET (custom turbo set-up) and play with that. But the VG30ET will be by far the easiest to put in that will make power. The easiest will just be a VG30E since it is what the car had originally.

Now if you're crazy, you can get a RB20DET to fit in there as well. But you'll need a whole drivetrain swap from a 200zr... and as far as I know these are kinda on the rare side.

What are you talking about weak crank they are the same internals as the 84-86 it is just a regular VG30ET they are all the same the cranks aren't any weaker. The only problem with a crank might come to pass at 450-500RWHP since they are cast and not forged.
