So does the kit have a special manifold or is it a modded stock manifold? I also saw what looks like the adapter on the back, is that a total aftermarket part or did it come off of something?And what does the adapter do besides turn the intake 90 degrees? I am kind of trying to find out that if I already had the supercharger itself, what the remainder of the cost would be. As a side note, the shop has only 1 working supercharger up for grabs, all the rest are(were) going to be rebuilt, and I got dibs on the 1, sorry.
