This is only possible if you dont have an AC rad in there too.

Only problem with a supercharged Vr, Is the centrifugal chargers only add torque/power at the top of the rev range. So you don't get the typical low down grunt associated with superchargers. You can get around 270hp from one but its possible to get quite a bit of power from very low boost on a vr, with a correctly sized turbo.
I've seen somewhere that someone made a good turbo manifold using the existing manifold with DP removed. Was a bolt on adaption.
