How fussy should I be about primary lengths/diameter etc? I've got the original manifold still as a start point and dimensions of a few race ones but i'm aware its got to be made to fit and everything is give and take when it comes to such things.

Anyone got good ideas for a system for the m3 lump!? I'm thinking 3-2-1 twice...

was it raven in sheffield you were going to? He did mine, years ago.

A place in Lincoln, bet i'll end up with a webbed manifold

Is it OJZ engineering ? Their website looks pretty cool

where in lincoln you going. i need my exhaust sorting too.

When i get round to replacing my tintops crached manifold, im going to go 12 - 6 - 2 - 1. I have only seen this done once but looked like a straight 12 at first
