Cheers mate :D

All of them?

Reason I ask is ive been looking at many a turbo manifold and they all seem to leave the steam pipe round at the port.... So you're sure all BPs are oval?

Thanks heaps,
Dann

If all BPs are oval, well then its because manifold builders are lazy.

Ill be building a log manifold (or 3) in the coming month or so. And I just wondered.

I think australia wants a manifold with a T2 flange, a nice sized dump pipe, and the ability to run air con and ps.
