42mm is on the small side for ITB's on a 2.2.
Vocky has an ITB 2.2 hybrid VX220, there's a lot more needed to get a set to run on the 2.2's but if you have deep enough pockets you could see in to the high 200's
still cheaper to fit a supercharger kit.
i have almost got a set of ITB's for a 2.2. set me back £1800 :eek:
