i take it as you drive a 1.4 its due to being young and needing cheap insurance? so you will be telling them you have modified your car? would cost you more to insure than buying a 182 in 1st place
...... BHP Vs Cost no, the gains are not worth it, and it would all be custom one off work, as i doubt very many people have done it, unless you are doing all the work yourself?
