Just have to agree, fabulous little car, especially the GT Turbo obviously.
Of course the phase 2 belted out a whopping 120BHP and whilst it could not beat the top end speed, it surpassed its "direct" replacement for acceleration, the Clio 16v.
I am not 100% sure, but I have heard of people being able to get around 160BHP out of the beasts, not sure how easy or expensive this would be though.
Of course, the phenominal mid engined Renault 5 Turbo from the early 80's coulld push upto 200BHP at standard, but these are hellish rare (and probably sold even less then the Clio V6).
Either way, amazing little cars, full of character, look good even today because of the GTT legendary status, hopefully one day I will be able to get one as well as a Clio Williams 1.
