The 993 manifold in theory will fit, however, it is the injector stands that you will have to adapt (making adapter blocks) to fit the 930 2 stud heads. Again the 964 and 993 have a 3 bolt pattern with a plastic injector stand that bolts to the intake port. Now, once you solve that issue you are then going from a 41.5mm port to a 32mm intake port (930 head)

I've tuned several MoTeC EFI cars with 3.6 plastic manifolds on them (964 and 1995 993) and they produce slightly more power than a 3.2 Carrera manifold. There are a number of companies that sell the 2 bolt to 3 bolt adapters (I think TurboKraft is one of them, talk to Chris). As long as the engine is apart and you are already building it for EFI with proper head porting then the manifold swap is not a big deal.
If you are talking specifically about the 96-later varioram manifold, I've not done one in a turbo application. With a good MoTeC ECU ,functionally you can control the varioram, however, in a turbo application, I don't think it will give you the same benefit of resnonance tuning it sees in a N/A environment. Additionally, with the adapter blocks, you will have a height issue between the top of the engine compartement and the varioram intake.
