I am pretty sure that the twins have a bad oil seal, or at least the rear turbo. (When I boost and rev past 6500RPM it smokes pretty good when I let off the gas.) But I am befuddled as to why at idle it will intermittently smoke. Sometimes when it’s warm its fine… no smoke. Other times it will just blow out a good bit of smoke. THE FOG! As I like to call it.

Anybody know why?

I have a judge Ito ported motor and poor mans non-sequential conversion.

 

not to be a downer but it could be the engine too.. an oil seal maybe going.

 

if you find you need a set of stock twins i got a set i'm trying to sell. name a fair price and yours.

My bet is the turbo(s).

 

Its a newly rebuilt motor, only 900 Miles on it. all new seals too.

 

I might be interested in the twins. What are you looking to get price wise? I am new to the RX7 world, and don't know what is fair. How many Miles on them, and will they work on a 94 FD Thanks.

 

I just can not comprehend why it would be an intermittent problem
