1st gen help!!!!!!!! engine swaps
 

I can't chosse with engine I want to put in my 1st gen rx7. The turbo ll engine or the twinturbo engine. Which one will go in without having to buy engine mounts. thanks

read the sticky. there's a lot more to worry about than just mounts!!

The first gen RX-7 engines mounted from the front of the engine. As installed from the factory, neither one of those engines you listed mounted in front.
