Really appreciate the replies chaps. For the most part 185Bhp is enough on a b road, the chassis is fantastic and you can use all the power. I love the Clio, but for the occasions I'm on a dual carriageway it lacks the 'shove' in the back of a full on performance car.
Having spoken with Mitch from Proline Motorsport a kit un-fitted will be around £3.5k TBC, which includes the C34 charger, pro alloy intercooler, pipework, blow off valve and a remap. Expensive, but looking at the price of the car + the charger kit and what else I could get for the money.. I say that its not bad value. Power will be around 301Bhp and 244lb.ft Torque.
@Sean197 yer I would completely agree that a turbo has more benefits in terms of torque and MPG. I guess I have a nagging feeling that I would like to maintain the standard engine just give it more power rather than put in a megane engine. If I had a ride out in one maybe I would change my mind?
