I dont know anything about motor mounts. I was told that mine were welded. I have a lsvtec in a 88 hatchback. Can I reuse the mounts. I wantted to put it into another 88 hatchback that is alot nicer then mine?
If the mounts are removable (however they installed the engine) then you can pull it all out and drop it into another 88 just fine. If they moved some of the mounts in your engine bay, you'll have to do it all over again...
Yes, moved the mount points. Go look at the brackets that are in your engine bay, which hold the mounts to body- the same mounts which hook up to your engine. Compare it to the other Civic. If the mount points on the chassis (not the engine) are all the same place, you should be ok for transferring your engine to the next car.
Look at one of my mounts:
The white bracket is the stock mount point on the chassis, the red and black piece is the actual mount, then it's bolted to the engine at its own mount point. If all those brackets match up from your car to the "new" one, then you should be fine with reusing everything you've got right now... at least for mounting the engine into the other car.
