Was wondering what compression I should be getting out of a 93 twin turbo 13b? What are good compression ranges before a rebuild is needed. Just got done prepping and during a five year sitting engine, with 50k original miles. Any help would be greatly helpful. Thanks

 

I think is 90 at least.. I've read other threads that say that theirs is 90-98 and they say its good. But I don't know much about them so don't hold me to it! Lol

 

I'm getting 100-101 across them all

 

That's good numbers for all faces. Check rotaryressurrection.com and go to tech articles and look for compression testing he lists appropriate numbers for healthier engines.
