Twin HS2's work well on small bores and help with the mid range torque.

If in doubt, flat out . Colin Mc Rae MBE 1968-2007.

The MG1100 had twin HS2s fitted as standard (at least the US spec one I used to play with did) and work fine.  I've never bothered swapping float bowl angles when using MG carbs on a Mini, but it's a doddle to do.

You do get a slightly better throttle response with twin vs a single, but to take full advantage you'll need to find a rolling road and an operator that knows what they're doing...

Metric is for people who can't do fractions...

If it's not broke don't fix it. The MG 1100 carbs will work but you will need to change the bowl adapters and a mini intake manifold to match. A rally car would have a pair of 1 1/2s. But yes you can do it. Steve (CTR)

My engine is fitted with a nicely tuned 1.5" SU carb on an aftermarket heated manifold. It starts easily and runs great but I would like to get some thoughts on if it would be worthwhile to swap to twin SU carbs like the European spec cars. I am thinking of turning the car into a Monte Carlo Rally Tribute so it is more for looks than performance while it is in my garage.
