hole in manifold

[Jamo]

That will work, you need to check the gasket goes around the outside of the hole though, it should do as the T3 gasket is quite a bit larger than the flange.

You could also get the manifold machined to a true T3 hole size. It is possible with the way the manifold has been made.

This may do the trick K27 to T3 convertor

That is a much nicer solution than just mating up a square and round hole as that huge flat surface area would surely have a nasty effect on the gas flow

However, at $125 plus shipping to Blighty , I would pop down to your local machine shop with a couple of brown drinking vouchers and get one made up yourself

Personally I'd machine the manifold if I was doing it. Suppose it depends on if you want to sell the manifold on in it's OEM state.
