My car is in my sig and I am wondering how much a Zex cam would give. I think there was some article on it in some magazine a few months back but I can't rememeber. Also the place that would install it doesn't have a dyno, only a Wideband O2 unit to tune. Would I see better results with a good clutch and Fidanza Aluminum flywheel? I think my clutch is starting to slip anyway. Also should I just get a camgear instead?
