Are there any engines that will bolt right into an FB and its transmission without much work? I would assume from mazda? or maybe not...

Thanks,

Are you talking about using the FB's stock transmission or a replacement engine's transmission?

I've seen photos of people dumping in Chevy 350's and Nissan 240SX motors. Altho, this just takes away the entire being that is the RX-7.

I know, but im thinking of it just temperarily. And Im talking about using the stock tranny and bolting up an engine that will just fit, any engines exist? I was thinking the MX3 engine?

The short answer is no. The closest engine to bolting up would be the 2.0L/2.2L engine out of a B2000/B2200 truck. Would bolt up to the transmission with the truck bell housing. Engine mounts would be different though. Its not a powerful engine though. A turbo version sits in the 626 so I suppose one could use that with a B2000 bellhousing but not sure what the point would be.

Lots of V8 swaps - search for Granny's speed shop for kits.

Think about the nature of rotary and piston engines. The eccentric shaft on a rotary is in the middle of the motor, while the crank of most piston motors are at the bottom. There are lots of packaging issues that make the conversion of a rotary to anything else a fair amount of work. It might be something that someone wanted to do for their own reasons and I have no problem with that, but it is a pretty unlikely thing to do temporarily. If you make a swap, it is likely the car will NEVER be changed back. Except for my car, of course, and that is a whole story in itself.

Rotary engines fit rotary trannies.....its as simple as that.
Engine architecture aside,the bellhousing pattern is unique to rotaries alone.
Just about any engine will slip into a 1st gen's bay,there is lots of room.Few will match the rotaries compactness and center of gravity though.

I think your missing the main factor.....and its not that an RX-7 MUST have a rotary in order to have a soul.... (to each their own,were all car people here)

The main thing to consider is this.....if you,yourself can plan and execute a non-rotary ENGINE transplant into an RX-7,then installing the TRANNY that is made for that engine,should be simple by comparison.
