Does anyone know the exact diameter of a 94/95 style inlet plenum, is it bigger or smaller the 70mm?. Thanks.
 
At the end where the TB is attached, the 94/95 inlet plenum is smaller than a 70mm TB. I don't know the exact diameter, but it's a couple mm smaller. It should be ported out to match anyway, so the exact diameter isn't too important in that case.

At the supercharger end, the 94/95 style plenum has an opening of approximately 37.9 cm^2. By comparison, a 70mm TB is 38.5 cm^2. The plenum should be ported out to match the supercharger inlet, which is actually a little bigger.
