has anyone ever run a set of twin inch and three quarter su's on an almost stock 1200, my ute has a webber and extractors but i wanna try these su's but i dont know whether the car will run any good or at all will i be just wasting money.also do inlet and exhaust manifolds off a 1200 fit on a 1500????

yeah should be good, i think the GX SU's are only inch and a half but they ran on a practically stock 1200, extractors would be good anyway if ya can get some

inlet should exchange from a-12 to 15

1200rallycar is right, these are nice carbs. I don't think those large SUs will be substantially better than a Weber 32/36 carb on a stock engine.

> do inlet and exhaust manifolds off a 1200 fit on a 1500?

Kind of. The A12 ones have small round ports. The A15 has large oval ports. The bolting pattern is slightly different as well (see Intake Manifold Comparo).

The 1500 ute engine is totally different.
