Project goals? Mo' powah! Most of the modified 944's are intake restricted, particularly the boosted engines. I'm doing this to encourage more 4V conversions (way mo' better) and to let them breathe. Adding boost to offset breathing restrictions leads to too many other issues.
The intake will be suitable for NA engines (big power increase with proper cams), and turbos too. The first effort is NA, then a proper plenum will be added for turbo use. I'll have to fit a plenum around all the other stuff in the engine bay. Anyone have the ability/expertise to lend a hand? I don't have easy access to a production chassis/engine combination.

I am in MD and have two S2 engines on two chassis. One is '89 original S2 and the other is '86 944 NA 8V. I also have access to all other production engine/chassis combinations.

Looks good! 3d printing makes the prototyping process so much simpler and accurate.
Those runners look really short though. For boost that would be terrific, but n/a I'm not sure that the volume would allow proper wave tune. You want the intake pulse timed to hit back the vales right when they open.
