they will more than likely class it as a modified 1.0 so they can get more cash out of you. it'd be easier and cheaper just to buy a 1.3. and that is coming from experience.
ha ha still wont catch me ha ha
How?
Still theres driver error that could come into play, I would put my mates old N reg against it lol I know it sounds funny but i would and I would bet on it.(Y)because his is a 1.4 dynoed at over 100bhp and a 1.3 with a 4 branch will be more like 95.
