This kit is complete nothing missing still a 6 rib kit with a 3 core sheet metal inner cooler and big red blow off Valve. I converted it a slot style maf so if you run a regular mass air you will need the adapter pipe for that which I don't have. Comes with a 6 rib 3.8 a 3.5 pulley and a 8 rib 3.7 pulley. Only trades I'll take is a hellion turbo kit for a 2v and no I will not just sell the head unit. Price is 3900.
