Thats right the older 220 Gti s had a M16 Engine and the newer coupe shapes had the T series.... The 220 Gti had 140 Bhp and the newer ones have 137 bhp....... The engines are mainly the same apart from some of the things like water pumps etc were moved for easier access..... They are very torquey engines and do fly when they are up in the revs for such a heavy car they are not bad....... I wouldnt personally go for one but my brother has had the older Gti and the newer coupe
