DIY Inlet Manifold

[Jimmyd]

Flyerncle you've explained it better than did, just the way I was seeing it in my mind!!,

"make sure the manifold flange and gasket are as closely matched to port size as possible, this way the fuel/air is not hitting the edges of the head and causing turbulence"


I may need to think about some head work.

on locost builders there was a thread about manifolds for a zetec and somebody had posted the size tube that when when squeezed in a vice deformed almost exactly to the manifold plate of a zetec if thats what you are using

40mm Id is very close to zetec port size.
