Only a 1.4, but i'd fitted a set of piper cams when I did the headgasket, not long since fitted a full scorpion system too, was pretty nippy to say the least. And it was definitely more comfortable, got shed loads more grunt than the SR but not as fun to drive as the turbo, handled very well, only downside was the tyres didnt give much feedback as to what they were doing tbh. Would definitely have another one though:D Day
