What kind of rotary motor fits in a 1982 Toyota cs ke70

 

welcome to the board.

the answer is any and none at the same time. as you're well aware, rotaries are foreign to the Corolla. however, it's been done many times over.

any of the engines will fit. do you have any specific concerns?

 

...reminds me to renew my "mad skills yo" ..
anything can fit anything..it takes determination,skill,competence ..and a BFH..!!

You may want to take a look at "other engine conversions" section..lots of info and ideas too.
The latest I have seen is a Rotary Bug and a Suzuki Samarai.,.

 

any of them are small enough to fit in your bay, its just making the custom mounts, driveline etc.
