Been doing some research and talking to other people and turbo sounds cheaper!
I mean i could make a manifold myself just about, just get my boss's mate to weld it up properly for me. Turbos are usualy cheaper then a SC12/SC14 too. Ill just plumb it back into the standard inlet too.

Would do a water/meth system too using the whole washer motor idea. I have a couple of free A12s to play around with and blow up anyways.
