excellent! i didnt like the way your car pulled on mine out of the corners at cc so im investing in some 86 camshafts - and im giving popov the boot as passenger (thats good for 110kg!)! where will you be saving weight? what do you think the relative merits of 968 intake valves are against GT cams?

I have the 86 manual flywheel and also the S4 auto timing ring. I am looking for information on ensuring the timing ring is properly oriented on the flywheel.
My guess is that the tooth gap needs to be located in the same place, but exact information is desired.

Stan, I for my GTS I simply used an S4 manual flywheel to ensure the timing ring was in exactly the same postion, I guess you could also use an s4 auto flywheel instead if you couldn't get hold of a spare manual one.

I think you may be dissapointed with 968 valves - very useful on a stroker or seriously modified engine, but don't expect too much. Given all the cost of removing the heads, modifying the pistons etc, probably better spending money in other areas unless you can do the work yourself. The cams made about 10bhp difference on their own, maybe more if you really rev the engine, but you already have uprated cams(?)
As for weight saving, can't give all my secrets away, but I've got a virtually standard exhaust at the moment to change, lightweight bonnet to fit, lighter alternator, PAS pump, and some titanium goodies.

The S4 auto flywheel won't work, as it is not configured to work with a clutch at all.
I hadn't heard of anyone using anything other than an 86 flywheel with auto timing ring before (except now for Carl F.'s option).

Stan I just meant I used the other flywheel to align the timing teeth exactly in the same place compared to the bolts holes etc with the 'new' twin plate flywheel. Don't think there is anyway you could use the original S4 flywheel itself with a twin plate.
