Check out these cast exhaust manifolds...

[Mihnea]

@Floddy: the SQ head is different from a 3B/ABY/AAN/ADU head and it did only have 2 studs per exhaust port indeed.

Cheers,

@Minhea: The yellow urquattro from irry has a S1 head, but that one has the same bolt pattern as the S2 ones. That means that the S1 and Sq has a different layout of the studs, or am I drunk?

Hmmm, dunno mate, maybe the SQ has the holes/threads for the additional studs but doesn't use them? I wouldn't have expected the S1 head to have a different head than the SQ though (KW motor)...

Looks like a 10v flange, but it looks like it would put the wastegate into the IM, unless i am looking at it the wrong way and it is placing the wastegate below, but then it would foul the oil filters.

Anybody got a normal 20v flange for comparison

These look identical to the few Audi made SQ manifolds that I have seen in the flesh (the last one was Habib's) or any pictures I've seen too.

Ah, found a picture.

As Mihnea says the OEM SQ manifold came with two-stud flanges. The MTM S1 manifold which I have comes with the four-stud type flange. Interestingly that is not the only difference, on the OEM Audi SQ manifold's no.5 runner joins the collector at the top, whilst the MTM version has the runner join the collector at the bottom.

Hi Mark
how much is the MTM S1 manifold?
Cheers Nick

Nick, according to their site 1630 Euros .

Mark.

P.S. you'll need a new downpipe though.

Oh what its like to be loaded hey Mark! More money than sense. Wish i bought the SQ manifold instead of my RS2 one Could have bought a SH one for the cost of the new RS2 one.

I'm not offering to get involved buuuuuuut, why don't you find what you want and get some made?

There are a couple of ways that manifolds can be made
1/ casting
2/ fabricating

Not being a sexgod in these matters but I would assume the cast option is preferable as the chamber size can be minimised to reduce lag and the wall thickness can be beefed up to provide strength and support the turbo+W/G. I think the Calibra turo had the exhaust manifold and the hot side as the same item. Casting has to e in high silicon cast iron or something similar.

fabricating could be done reasonably easily but a nasty job to do I would have thought.

Either can be done in this country 'the home of the Quattro' well its as english as the owners of Rolls Royce and Bentley are!

That would cost loads!! It would be cheaper to have a tubular manifold made from SS, i think.

LOL, not anymore Tom (as if I ever was), I would love the MTM inlet too, but I cant have it .

Tom, limited production runs of heads mean they end up costing 2K with valves etc. they are a lot more work. I will check with someone about this.

birmingham will have someone who could quote I feel. as for quality, look at the MTM inlet manifold, not true German quality I feel and aluminium casting is cheaper anyway!

The MTM 'S1' manifold.

Dalback sell this as the sport quattro manifold... But doesn't list it as the mtm version.
