The guy asking this question is the same guy who thinks it is perfectly ok to put an ST150 engine in a lower model shell and not tell the insurance company about it. If this is your grand plan why bother insuring your car at all because it would be a waste of money as the insurance would be invalid any way, hell dont tax it either as you will be paying the wrong tax for the car also.
Your young, inexperienced and your insurance will be high, deal with it, we all managed.
