It's .64 ar I think. I suppose it depends on what engine the turbo is on. I know the CA18 has a head that flows very well. If I was to maybe fit it onto a Renault 5 or something, it might be able to do higher boost pressures.
I'll be fookin pissed if it's dead.
Is 1mm in and out movement usually enough to mean the seals are fooked?
