I think you're going in the wrong direction here. It is important to remember that the 934 only had CIS on it to comply with racing restrictions that the car resemble the production model. CIS is not a performance injection system, and cannot be used with aggressive cams. The CIS system on the 930s should have been scrapped (in my opinion) in 1984 when Porsche introduced Motronic. However, I doubt they sold enough Turbos to justify the costs of redeveloping that engine's injection system.
