X3 I've built my kinroad up to 155 (didn't have to mill the case), done my own headwork (I've drag raced all my life so I like to think I know how), an a11 cam, built an exhaust, bigger carb, uni, intake spacer, and 11 gram sliders. Mine will jump off the line and still bump 40 mph (gps verified). One of these days I'm gonna mill the case and bump it up to 180.
Even if you have never turned a wrench these little things are pretty simple and easy to learn on.
