i was lookin at a 92 prelude for sale it was 500 but tha engine was locked up what could cause it to lock up

 

water, rods, crank walk, oil starvation, list goes on & on my friend

 

#1 cause of engine failure is retarded owners.

 

I know a locked engine is pretty serious thing, but if everything else looks ok, that could be a good deal depending on what your plans for the car are. I don't think I'd count on being able to reuse that engine though, without actually knowing what's wrong with it. Some things are minor and are rebuildable, some are not. Without knowing, I'd just plan on not being able to rebuild it.

 

i would put another motor in it but i didnt want to if it wasnt necessary just seein if it could be fixed

 

The answer is maybe. But don't bet on it. You'll at least be able to get some parts from the other engine no matter what, and of course the harness, ECU, etc.

 

have it inspected.

chances are your better off getting a h22a

 

What he said. Honestly, you can get the H22A JDM motor for pretty cheap nowadays, and it pretty much drops right in without too much of a hassle. I would switch out SOME things, like replace the auto-tensioner with an H23 manual model, but overall it has potential. But like what's been said, it all depends on the route you plan on taking with the car. Either way, good luck.
