If you are refering to removing the 930 recirc-valve/bov and replacing with the 964 style elbow and recirc valve I think there is still 90 degree bends there but the recirc-vavle is much more efficient IMHO (make sure you get an aftermarket one tho like Forge, etc. as apparently the plastic fantastic ones don't last).

You are basically just replacing the old large valve body with a small compact one less prone to leaks oh and you will probably need a long-neck ic to reach the throttle body too.

If he means just replacing the pipes I don't recall there being much difference between the 930 and 964 but I am sure (as others have) fab up much straighter more efficient pipes.

'95 993 Turbo - Silver
