If I understand it correctly, the 182 is the 172 engine with a new inlet manifold, ECU and free-er flowing air filter. So, mod the 172 with those parts (minus the cams) and itll make very similar power to the 182. No point in fitting the parts to the 182 as they come free with it!!
tonykart - have you fitted some or all of these parts? If so, please tell us of your experience with them. And whats so bad about the cams? Is the cam/ECU package from Renaultsport a GroupN rally setup or something i.e. not really suitable for road use?
