sorry for the late reply...oops been really busy.
The stage one kit is a really good upgrade for the 998cc minis...doesn't give a huge increase in BHP but does give a greatly improved torque curve! so when you hit those hills your not instantly changing down a gear! make the car more responsive as well. Also if you change the engine at any point to a 1275cc unit the kit will fit that as well...just need to change the needle and spring! I put the new needle & springs in our kits because it's need to get the fueling correct! a lot of company's don't supply these with their kits and the frustrated customer usually ends up on the phone to me to explain the problems they are having! I put a bit more thought into our kits so you don't have to
