The vx kits may well be more due to fly by wire throttle and small volumes though a bet plenty of 2.2 Astra owners would be interested?
I had the silver kit (twin 45 carbs) on a 2.0l zetec engine with a 4 branch manifold to a straight through exhaust in a Tiger Super 6 (Westfield clone). It sounded fantastic but the gold kit (TB) sounded almost as good

I would love them on the vx.
