ok with a little research all the answers are out there.
Basicly you have two effective options some are more comportable than others.
1.) either you can strip the entire body off and just have a rolling chassy and weld a frame to mount a seat to. Loose all the weight as possible and it will be faster.
2.) or you can go with a mild turbo set up with low boost about 4-5 lbs and well it will make you smile with a slight gain in power.
or you can go all out with about 10 grand and go with a high boost set up and try and make 500hp and have aa perminant grin from ear to ear as you suprise everyone you race.
First i would figure out what your wanting to do from scratch and plan your goals and finances from there its all just a matter of money and what you want.
