What specific engine would fit & work into an 83' RX7?
 

You should be able to fit any one of the engines that came in the car that year in the car with the correct cross bar and motor mounts. These engines include: 2.5 L AMC 150 I4, 4.0 L AMC 242 I6. As you can expect the 2.5 L would be the easiest install. You may be able to fing the motor mounts you need at a local junk yard. Installing any new engine would be difficult. The only worry I have is you might run into problems with the accessories.

I know a guy who put V8 in it! Just as Patrick mentioned you can put any engine you want. It's up to you how much modification you are willing to put into. All depends on what you want out of your ride.

why do you want a v6???


if your swaping for something bigger why not go lsx

just say-in

My question to all who swap rotary to piston into RX-7... that's what RX-7 unique.
