So we all need a DBW inlet manifold to butcher modify with a Dremel/die grinder to get a few more horses out of our earlier cars!  

no andy dbw exh manifolds  

I re-read it too.
You'd then have the EGR to bugger about with then.

Any chance you'd be able to get some pictures up Mark of both manifold styles to compare??

Yep, give me a day or two so I cna strip them off...

The EGR would require the valve keeping, does not have to be kept plumbed in though!

That's what I thought.

Already working on a blanking plate for the inlet where the EGR attaches...

[PaulW]

Also... can you use pre-facelift exhaust manifold gaskets on the facelift manifolds??  As I just bought 2 pre-facelift gaskets  :-/

Also noted on EPC that the manifold stud nuts were different P/N between manifold types...

A blank wouldn't be difficult, it would just need the valve itself moving/supporting somewhere within a radius of the cable.

Aye, I've got some 5mm copper plate I can use to make the blanking plate, so once I've got that marked & machined to size should be onto a winner

EGR valve could possibly be relocated anywhere to be fair, I'll have a play and trace back the egr connection wire in the spare loom I have, see if I can move it somewhere inconspicuous

Gaskets are different to the 3.0 and 2.5 ones

I know, I have 3.0 gaskets for the 3.2, but if I adapt and use 3.2 manifolds, can I use the 3.0 gaskets??

Probably be a resounding No  

[VXL V6]

Gaskets are metal sheet on 2.6 and 3.2 with larger cutouts

The 3.0 ones I have are metal cutouts...  3 layer

[Marks DTM Calib]

Might be possible to use them

Here are pics of the manifolds


Early cast item top, later pressed steel bottom, note how much wider the pressed steel version is and consider also the wall thickness is much less than that of the cast part.



A view in the exit, note the smoother opening of the pressed steel item (right hand one), there is still a step, but, its much smoother and less pronouced on the later item



A shot of head facing port on the early manifold, you can see also the milled duct for the air injection.



A side by side shot, the inernals are much more free flowing on the later item (right hand pic)



Top shot of the pair

A few pics of the heads, can anybody guess which ones have had the worst leaking stem seals!

Exhaust ports



Stem seal on the left valve is fine, right hand valve stem seal is shot!

[Marks DTM Calib]

I should add, those heads are gonna take some cleaning!
