After i chg my throttle body, all belting ( timing, fan, air cond), re-fiber muffler, my car speedometer can't reach even 120km/h.. What is de possibility?
dunno what's wrong, but if i were you, i try change things back one by one and see if the problem goes away or not, can find out which one is the culprit.. at least..
Many people hate the idea of putting a V12 engine in a skyline. They say it makes the car too heavy or it will disrupt the weight balance. Not for this...
