i found another fc, this is a 86 rx7 an it is claimed to have 70,xxx orig miles would it need a rebuild

 

Why would it need a rebuild? A rotary can go 2-300k miles if taken care of.

 

ok but would the seals be worn out fron getting old, my last one i had a bad exprience with, so i want to make sure this is a good one

 

carfax? i bought mine with 88k and it runs golden. i see no need for a rebuild

 

If the car runs fine, drives fine, makes good power and starts easily, then it won't need to be rebuilt.

There is no rule that says an engine needs a rebuild after so many miles.

Perform a compression test. Three even bounces above 90 indicates a good engine.

 

Drive it and it it drives and sounds fine then it most likely won't need a rebuild.
