I have the zex system, its awesome. I would definetly get it. just spray above 3000 rpm's and all will be good. little piece of advice get a stage 3 race/street clutch. you will be replacing it if you don't. I went through 2 stock clutchs and my car only has 7000 miles on it. now I have the stage 3 from clutch masters and it's awesome. be careful it's addictive!! hehehe....lol<img src=icon_smile_big.gif border=0 align=middle>
