I can't really shed advice in terms of what motor to swap in. But it can get pretty expensive; it may be better to see exactly what is wrong with your current motor. You may be able to save/use the rotor housings towards a rebuild.

Because I honestly doubt you will find another "new" / "Strong" motor that someone is willing to part with at a decent price. It will most undoubtedly need a rebuild before long.

If everything checks out within specs in terms of housings/irons/rotors; your looking @ around 600$ to close it back up.

Given you said the motor was abused I really cant give any estimate in terms of pricing; the bearings could be bad. The previous owner could have pinged a rotor; or done all kinds of damage to a rotor housing. Its one of those things your going to need to crack it open and see EXACTLY what you need.

Sadly its not like a piston engine were you can just buy "said kit" and bam your good. It all depends on what it needs when it comes to a rotary engine.

I wish you the best of luck. Rafe.

Should bolt right up. I believe all rotary trannies are the same bolt pattern

does this mean your car is an SE or a 12A car that was swapped to a 13B? it may make a difference in terms of work and overall cost of replacing the engine.

engines all share the same bolt pattern as far as the tranny goes.
