I just got a 1992 240SX 5 sp in on trade. It came in with the engine in pieces. I have been told that it spun a rod bearing. In looking over the engine, I can confirm this. Judging by the damage, I get the feeling I'd be better off either finding a new crank and connecting rod, or just a whole running engine.
The problem is that I'm having very little luck finding crankshafts or engines for a decent price. It seems that as soon as you mention it's for a 240, the part is made of solid gold. So, this brings to mind a few questions. I have an ragged out beat up old Hardbody with the Z24 engine. Can I use this engine? Are there any other Nissan cars or trucks out there that have interchangeable bottom ends? Any of the FWD cars or automatic cars? I'm a Nissan newbie at this point, so I'd appreciate any insight you all can provide.
Another question I have is in regards to rebuilding the engine. Am I better off rebuilding what's left of the engine I have, or trying to find a complete engine that either runs or needs to be rebuilt? I've heard that these engines have bad seals and leak oil a lot. Is this true?

Main bearings are different.By the time you would machine the bottom end to fit a KA crank it would cost you more than getting another KA block. Plus you would have to use an Altima or truck head for OBD1 I believe, 240sx heads are a bit%$ to modify on the NAPSZ engines.

Would that be assuming I'd be using the Z24 block w/ the KA crank? The problem isn't the block, it's the crank. The rod bearing was what spun. Is it possible to just use the entire Z24 block and bottom end to avoid any main bearing problems? Would the head just bolt on, or am I SOL?

Bump this up. Someone has to have some answers for me.
