Cam timing

[c.h 90]

I understand that to time a 197/200 you need a specific cam lock with a 7 degree advance on the inlet.
Can the engine be safely timed with the none 197/200 cam lock? Or would it be apparent that the engines timing was wrong?

There is a cam locking tool and both cams are level, there is a group N timing tool for the 182 Clio that I think advances the exhaust but the map has to match. I have never seen a 197 group N timing tool.

Video of a 182 timing belt change they guy uses the group N tool for it after adding 197 cams

Right that clears it up. Factory setting on all f4r engines the cams are locked in a 0 degree position. Where as the group n spec is 7 degrees of I let timing.
I don’t see why it cannot be done to all f4r engines provided it’s mapped correctly.

Well if you are going that far you would be better with performance cam shafts and get some real gains.

Fair, I just wondered if you were changing belts would it be a nice little top end improvement.
