A number of the guys on here have the 2.4 from the Marea? with a bit of tuning it will reach 200 horses, some of the way out guys have put a turbo on it and then the sky's the limit! The engine on mine cooked within 70miles of buying it, I didn't have much idea of the performance prior to replacing it, had I have done I'd have been tempted to go for some more power. However it's not just the engine you need to think about if going for a big increase, all the add ons will make it an expensive option,.
