:confused:I'm not sure about what you mean...
If you want to swap an e36 m42 into an e30, you're going to need a lot of stuff...e30 engine mount arms, maybe the exhaust downpipe, clutch & flywheel, possibly a different manifold, intake, airbox, the list goes on and on. Just buy a 318is...if you can find one for less than $2k you'll be ahead on the cost. Find one with a blown engine and you're golden.
