Outer Limits 4x4 Board

I looking for the bolt pattern for where the twin SU carby "Y" adaptor bolts onto the manifold on early rangie's. looking at alternative carbs for a suzuki engine.

also what are the jet settings on a single rangie SU. Would just one satisfy a 1.3 ltr 4cly or would it need the jetting increased.?

thanx

The manifold is fully cast, no adaptor to the carbs

You would need to reduce the jet size, MGB's sold in the US had a single stromberg cd carb on a 1.8 ltr engine so an SU would be the same.
Rover 3500's had su's but i think all rangie's had the strombergs.

I have seen some at a wreckers that have a "y" piece that bolts to the valley manifold and then has the SU or strombergs conected to it.

Anyone have any pics of the setup?

On what vehicle ? rover V8 manifolds are cast in 1 piece they have never had a bolt on Y piece. Some guys that have p76 4.4's have made up adapters but none were ever made by the factory.

yeh it could have been the P76 engine but you know what im refering to. will see if i can get a pic of what im after.
