rally1200, what sort of branch are you running, reason, from my trial measurements it looks like I will need to come straight out from the intake ports and then turn with the intake pipes to clear the branch. Other option I have is to just use a very thick flange on the intake side to make life easier.

lamb_daiquiri: Thanks for the very informative info, it looks like I will go with the MS option, down here in Cape Town we have a shop called Rowlands manifolds www.manifolds.co.za they do sell a 1400 - side manifold intake and then they also do a side - rxi throttles, made from cast alloy. I'm only concern around the amount of space it will take up. The other option is to ask them to make ma a 1400 - rxi manifold.

Maybe I must just try that option first, I anyways also have to get a manifold made for a Ford Zetec - rxi. Maybe it is a good time to start a business relationship.

1200GXman: as for choking, if my math is correct, it is just a matter of pressing a sleeve into the intake runners after the butterfly.
