ok guys, garret turbos measure the exhaust housing by a/r.
how do you convert that to cm? just to get an idea of the size id be comparing one too.

such as a .63a/r
and a 1.06 a/r

what would them two housings be near ballparkish to like a turbo that measures in cm squared?
thanks

 

what turbo are you looking at purchasing dan? this will give me a better idea of where to start . what was your old turbo that you had the ar both exhaust and intake size.. manufacture..what size wheels etc.
