Not doubting or slagging the car off but the only thing I find a bit of a concern is the 'still logged as a 1400cc' bit
if someone buys the car goes down the road and God forbid has a serious accident they will be in shit street
if you mod a car with a million horse power and lots of blingy bits ffs tell the insurance company and get the correct cover, it will save you a lot of grief and money in the long run,
if you can't afford the insurance then don't get/mod the car end of
