Just had a reply from JamSport;
"We’d have to make a one off kit for you, which would be in the region of £3500. It’s difficult to quote an exact price without seeing the car and knowing exactly what needs altering. I can’t really estimate a power or torque increase either, but we’d hope for 35bhp at least."
Found this re:the C30 supercharger which they would fit
http://www.powerenterpriseusa.net/Power ... e_V1.6.pdf
Basically been speaking to the guys there and they reckon they could get anything from 35hp to 135hp added from one of these little superchargers, depending on how highly tuned you wanted it. They warn that the more boost they give you the less reliable the engine will become.
Remember the price is for parts, fitting, tuning and exclusivity (nobody else has done this before on a BJ, we would be in our own little club

).
They said they would be interested in Group Orders as this would cut down the production costs of the kit, the more people interested the cheaper the kit gets, so, anyone interested in this?
I am, so;
