WTB intake manifold 930 110 934 00

I am looking for a Porsche 930 intake manifold 930 110 934 00. I am trying to install a 930S intercooler in my 1988 930 and had not realized that the manifold for the 930S/SE M148 engine package is a bit different than mine.

I spoke to Marty about this, and the intercooler outlet's angle is like that found on a 3.0L -- approx. 20deg from horizontal, instead of the typical ~35deg of a 3.3L 930 and 964T.
No explanation why.
The last two real 930-S cars we worked on (1x very early, 1x 1986-) both had ~35deg angle throttle bodies and intercoolers.

If you install a flatter angle manifold (3.0T), you will next find that the throttle body pull rod is the wrong length, and its lever the wrong angle.
The 3.0T manifold is also missing the large port for the AAR, and most accessory ports and mounts are in different locations than on the 3.3L.

Thanks Chris for your input. It’s a bit of a puzzle for sure.

A friend of mine had a 930-S with the same manifold as mine, no issues, but his didn’t come with the same larger IC, something they did in later years maybe. Some also had a taller decklid, so maybe this IC was from one of those models.

We’ll see if something can be fabricated to make it work without damaging the IC or manifold. If not, and assuming I don’t find this other manifold to try out, I’ll probably go aftermarket on the IC and let someone else figure it out.

Easiest solution(s):

Remove the throttle body, and "install" the intercooler in place. See if the hot charge pipe between the turbo and IC lines up correctly.

If yes: cut off the intercooler's throttle body ring, reinstall the throttle body with the ring on top, and weld the ring at the correct angle/position

If no: install a different intercooler
