Hi, bought a new vr6 engine to replace the one thats cam chain went and damaged the engine. Looking at the new one it has a twin cog for the double chain where as the old one only had a sigle cog, does this make much of a difference? Another thing was the clutch, it's a LUK clutch and i dont know how high performance that would be, looking to get a decent racing clutch but not spend a forture. Can anyone give me advise for the finishing up of this replacement. Cheers
