Imo I think its a waste of time, having had ZR120's and my ZS120, then my ZR160 track car for the little performance gain I dont see the point. The 160 is only any faster at really high revs. Though the mid range id say the 160 has a slower throttle response than the 120 anyway. Add in the time and cost of doing the conversation, the possibility of VVC faults a lot of those engines are having now cant see why and tbh I've never seen a stock VVC engine make 160PS anyway. I would go down 2 routes if you want more power but don't want to pay out big bucks for a piper cam kit, throttle bodies and so on.....
1. VVC exhaust system (4-2-1 and one catalyst), MGF 135 cams, 52mm throttle body and a remap.
