unless you want to stick with a a12 i would recomend upgrading to a a15 motor, it make more power stock before you start moding it. remember that you should modify the whole car, brakes, suspension, rubber (tyres) ect. it also depends on what you want from the car as to what you want from it, i.e. daily driver, weekend racer, allout track car....

im asumeing that it is currently stock as a rock, so a brake upgrade would be a high priority. the b110s had crappy drums on the front and are rather scary when you start to drive a bit harder . look in the tech section for upgrades, it has been set up for new people like your self. i used it when i started and found it very helpfull.
