#1 Triple SU S1-S2 compatibility

Post by ralphr1780 » Sun Feb 17, 2013 9:33 pm

Hi,
I have been proposed a triple SU set with the inlet manifold.
It is coming out of a 3.8 S1, and seem to be in good shape.
Since I am running with a 4.2 S2 (twin Strombergs), guess there could be some issues with the water connections. How difficult would this conversion be? Recommended or better to wait for a true 4.2 manifold?
My twin-Strombergs run like a charm, the conversion is tempting only as an eye candy!
Thanks in advance for the valuable input as usual!

Personally I would wait for the 4.2 version. The inlet manifold is very different in looks although it probably fits. Of course if it is cheap buy it then sell it to fund your 4.2 purchase 8)

Burlen can supply a new 4.2 manifold.
