Hi well recently I decided that i was going to sell the vr6 as I use the audi tt all the time but i have decied to put a bit of cash into it over winter, so was looking for some advice on what to do next to it, Its a OBD2 engine it has bmc cda with cold air feed 2.5 exhaust system de-cat schimmel 263 camshafts ( getting fitted soon ) what would i be best to do next?? would a 6 branch manifold be worthwhile? whats the cheapest i could get a supercharger kit for? thanks
