between a 1.3 mk1 and a 2.8i with a twin turbo conversion, yes, a big difference, that pic is a JPS limited edition, a 2.8i special is the one to have or the last of them the 280, but if insurance is a problem a 2.0 or 1.6 is ok but not that fast, the 2.0 or 1.6 could be uprated easy to a 2.0 cosworth and the 2.8i can be upgraded to 2.9 24v.
