I have a T34 turbo on my saff 4x4 which has been on it since i bought it a few months ago.

Is it possible to identify what size of exhaust trim it has by looking ie .55 or .63 as i am planning on upping the power from the current 330 to over 400 and i could therefore do with the larger trim.

 

If you look closely i seem to remember it'll have the number on the casting. i.e. 0.48......

 

it has it on the bit that mounts to the manifold it is hard to see when in the car though
