Why spoil a basically well balanced car with a turbo. Putting an 18T in a 12 would give lots of torquesteer. All a stock (1289cc)Renault 12 needs to make it better is a 12G/17G five speed and the 12G/17G 5.5 inch wheel rims, also a slightly thicker rear roll bar helps.
As an added bonus over the Pug 306 you get heaps of room around the pedals too!
