Hi guys im new to forum but wondering if someone could help me, i just done a full rebuild to my r32 gtst i put the engine in and all drove fine then i changed cross member but while changing my gbox fell of the jack and pulled driveshaft and engine down i dont know if this is what caused my problem but my car vibrates/ shakes reali bad when i rev it even when it is in neutral i have jacked it up and checked my engine mounts and my gbox cross member everything is tight and i have looked under the car for anything shaking while being i reved i saw nothing moving bad at all.

have a good look at your engine mounts? but iv done the same thing before and not had any problems

If its shaking when free revving something rather nasty is happening. loose flywheel, badly out of balance rotating assembly, loose balancer etc...engine mounts are not going to have anything to do with your problem
