Twin SU HS4 carburettors pair of 1.5"
Pair of new 1.5" SU carburettors with rod linkage, but no heatshield, fuelpipe or manifold included. 
You will require a "T" piece or a link pipe to run the fuel system if your original carburettors had the twin inlet/outlet on one float bowl lid. Twin HS4 SU carburettors have been the most popular performance tune for the A series fuel system since the early Monte Carlo rally days. There is no question about the performance potential of this set-up, as your old and worn out carburettors can provide very disappointing results. Twin carburettors on a good manifold with quality air cleaners easily fit under the bonnet of the Classic Mini car and could perform as well as the highly popular side draft Weber!
