Jason, How about sending me the 3D piece?
Just to clarify are you referring to the printed piece or the CAD file scan?
For sure I can do either.
Definitely can send you a version of the printed piece.
I will check with Joe how easy it would be to print a second one potentially; after initial inspection in case anything needs correction that I can visually see prior to a test fit.
I will be seeing him soon.

Sir @michaelmount123 refreshed a 968 head for me and it’s still in the box he shipped to me. It’s been a couple of years and I haven’t used it yet, so let me know if you’re interested in it.gruhsy wrote: Tue Jul 07, 2026 2:08 pm I just got off the phone right with Joe at Fidelity Machine.
It’s being 3D printed right now.
Will post pics when done.
He was going to CNC it out of Aluminum but I thought it might be best to 3D print it to test fit first.
I might be able to use Soloracer’s 968 turbo to verify fitting it to a 16V head.
Trying to find a 16V head in Canada other than a new one from Porsche has been impossible.
Michael I can potentially ship one to you for test fit if Soloracer’s car is not available.

Is there still interest in this??

I'd definitely like to see a printed piece. I'm mostly interested in the port shape and size. I could make any changes to the printed piece ports based on past experience and/or flow tests. It could then be scanned for a final design. Here's an issue: At one point I had believed a set of four individual pieces would work with three identical pieces, and one different one. I now realize each mounting needs to be unique due to the bolt spacing and layout, so this needs to be worked out. The manifold could be a total of two pieces with two intake ports on each piece depending on machine capability. A 4V intake gasket shows the bolt layout, although I'd like to change the center 8mm bolt hole.
The 968 has a larger intake port than the S and S2. In the past I had machined all of them for an S/S2 port, and enlarged it for the 968 as needed. Perhaps two different files could be used so that there could be a S/S2 version, and a 968 version (mounting bolts/studs are the same). I supposed this would depend on demand for these manifolds; I don't want to muddy the water. I like the KISS principle.
Once I have a chance to examine the printed piece, I'll assemble questions for Joe and try to make the machining as simple as possible but also ensuring there are no compromises.

That sounds great
Okay if I get myself a 968 intake gasket that should help. I would need one anyway for a build.
I will call Porsche today.

I just ordered a 968 intake gasket from Porsche
Thanks for the heads up on it being one solid piece
Solves the issue for bolt spacing.
I can’t believe it is a whopping 19$ dollars Canadian
I think that’s the cheapest Porsche part I have ever purchased.
That’s like 5 cents US these days
