my friend just blew his motor on his 87 and was curious how much it is to replace or if it would just be cheaper to rebuild?

 

You can find a used JDM motor for about 800-1000, Could be low mileage but no garentee

Or

You can buy a Master Rebuild kit 800ish and a rebuild video 40ish and learn somethings that you may not have known before. But the problem is if you have a blown motor you will need at least a rotor housing and a rotor.

I would go with the rebuild. Anyone can rebuild these engines if you take your time.

 

How hard are they atually to rebuild with the right parts?

Is there a big difference in performance rebuild stuff and standard rebuild stuff?

 

The cheapest jdm engine i found was 1599 and it came with everything to swap a na to a turbo. is that to much?

 

$1600 for the engine, wiring harness, computer, clutch, pressure plate, flywheel, slave cylinder, drive shaft, rear end and axles is a good deal.
