i blew my un modified 12a non turbo up and am currently pulling the engine out to fully recondition it, allthough it only really needs some new seals and gaskets i want to find out the most suitable ways of porting, and modding it up without turbo-charging it. what are the diferant seal ranges, and im looking at a new diff and clutch, flywheel etc.

it is a oct 83 84 limited addition 12a turbo rx7, its in beautiful condition and im proud to be the owner of such an amazingly designed built sports car. i am the 3rd owner and the second put a standard 12a in which curently has 161,000km. id be greatly open to any suggestions, advice and comments. greatly appreciated.
Oliver.
