I am going to see a 20b Cosmo for sale later this week and I want to make a compression test. Is it the same procedure as a 13b/Rx-7 ?

For a 20b, is 80-100 psi good like on a 13b ?

Anything else to check (mechanical, turbos, ...)

Thank you !

 

nobody knows ?

 

It's the same process for both as both engines share the same rotor housing internal dimensions.
