I think it woud be great to use the 968 lower section because the injection mount is already there. vs taking a blank, like Obehave's and have to fab up that part as well. If the 968 is aluminum, it seems that it could be cut and then a connecting tube welded to fit to the aMV8 intake. carls wouldnt work as its plastic, and the only option there would be for hose clamps and tubes. doesnt look like there is the room or angles to make that work

so, no porting the 928 head.. this means we cant use the 968 runners, but it sounds like with those blanks that Obehave have, you could weld "tubes" to that and make them point to the AMV8 intake at whatever point makes the offset angles and distances work. thats the big question and im sure not a trivial welding , fitting task.. but it still looks doable.... only .5" offset on each runner and a little bit of spreading the two sides outward an inch.

Porting is made in the divided ports.

anyway, arent we talking about the ports of the end of the runners of the 968? so that they so large, doesnt have a step down lip when mounted to the 928S4 head port entrance? i think thats what greg is talking about

i always get the 944 and 968 stuff mixed up. so, 944s are 2 valve and 944S2 is 4 valve, but the heads and cams are more like 928? that sounds like a better fit, especially if they are aluminum as well.

944S is 2.5L 4V, similar head to a 928S4. They have a magnesium intake manifold.
944S2 is 3.0 4v, similar head to 928S4. They have aluminum intake manifold.
968 is 3.0 4v, similar to S4 but with the variocam added, larger valves and HUGE intake ports. Aluminum intake.

interesting that the S2 also has some nice angles inward that might make the adapatation a little easier with the AMV8 intake.
ready to pull the trigger on the AMv8 intake. found an almost new one for less money than the first one i found.
this picture is actually the S2 intake. thought it was 968....

Again...I wouldn't waste my (your) time with the AM intake.
I've tried to adapt "other car" stuff to my projects before...it never works out.
Just remember what it looks like...but come up with your own design to fit the 928.
A pair of S2 runner-sets with a common plenum would probably do good.
in the S2 (3.0L) the car makes 208hp at ~6000rpm and ~200tq at 4000rpm.
