[QUOTE="singlespeed, post: 146839, member: 264"] There were already cams for the non-VVT K4M engines and these new ones were measured up and machined against a spare cylinder head and original cams to include the square lobe on the camshaft and VVT oilways which the older version engine didn't have. Then, different shape lobes based on longer duration and higher lift much like any other fast road upgrade. What do you mean by major development? I've put over 2,500 miles on mine already and pulled to the raised shift light more than a few times (Also, hit the limitter once) and all seems to be fine. If the cams are fitted as intended then there shouldn't be any clearance issues. I changed the spark plugs out last week and theres no sign of overheating after pulling high revs and then immediately switching off the engine and changing the plugs to save any overheating being masked by low speed /idle running afterwards. I probably spent more on the Audi and the MR2 previously, and the Twingo is probably more fun... so no, I don't regret it :mrgreen: [/QUOTE]
