Over the winter I mentioned that the wifes 92 960 had better accelleration than my 94(just seemed quicker & smoother).Over the weekend I pulled them side by side,popped the timing belt covers and brought them to T.D.C. as if changing the belts.
I spent at least an hour comparing cam positions on both.The method I ended up using was laying a straight edge across the shoulders of the cam bolts,1 on the exhaust and 2 on the intake.the 92 looked as if the bolts had never been touched and the 94 looked like it had been moved at some point.On the 92 there was a 2 mm drop on the center bolt and 94 had about a 5 mm drop.
I finally adjusted the 94 to where the straight edge was even across all 3 bolts top and bottom and then nervously reached for the key to apply ignition.Fired right up.the 94 does seem to be a bit quicker and the smooth idle is even smoother and appears quieter at cruising speed.
I will have to wait to compare both cars ,ie,driving one then the other to get a feel in performance.
There is a cut out on the timing belt cover(the 1 still attached to the egine) over the intake cam pully that has lines and numbers on it and the pulley is lined up perfectly to the cut out.
It worked on mine, so DO THIS AT YOUR OWN RISK if anyone attemps it.If I had access to the cam timing tool I would certainly have used it,I'm courious now to find out how close I am to nirvana at my backyard adjustment.
