I have basically the same build. The only difference is gt35 turbo, single plug and EFI. I did own the car when it was CIS. It originally had sc cams and I went to 964. That is a lot of boost for CIS if you ask me. I can almost guarantee you will not get enough fuel with that much boost and the size of the motor , even with the fuel head modifications. I could not get enough fuel running 1 bar. So I bit the bullet and went EFI. Even with CIS I got full boost between 2800-3000 rpms, and the car was great. I really did not want to deal with the headache of the fuel head anymore so I went EFI best thing I did. If you are going to buy a turbo I would definitely go with a gt35. I had a K27HF and there is no comparison compared to ball bearings.
