I did post to your question in my install thread. Stay away from the BBK crapity, crap, crap,. Prior to doing my install I did a ton of research, this was the advice that was given to me by people that I know wouldn't steer any one wrong. There are paxton kits, and Vortech kits that are still available. I can point you in the right direction for information and contacts that will blow you away with a range of knowledge, to make your install as successful as possible. As with anything it takes time and patience. After seeing the numbers I put up, if you still wish to go forward with this PM me any questions you have. If I can confidently answer it, I will if not I know some one who can. For now keep you eyes open on ebay. they do pop up every now and then. Kits for the 91-94 ranger/Explorer, paxton or vortech is what your looking for. As I'm sure you know supercharging you vehicle in stock form will work, but the support for the S/C, I.E. MAS, Injtr's, TB, CAT back, Headers, Apten, ect,ect,ect., the list goes on and on, really should be purchased. If your lucky Brian will have enough pages of data from myself and others that have done this, to where your tuning will go smoother. Any way stay tuned and keep your eyes open for some deals on the board and ebay.
Later,
Jeff
