That sounds like a cool project!
Have you thought about FI? Whether it be a Megasquirt system, or trying to retrofit a 929/954 FI system onto your engine.......I guess the only issue with using the Honda system would be the cam sensor in the head(unless the 929/954 doesn't have this.....). I'm not sure if you would have to get the carbs modified so they work properly with boost being applied to them (even with the carbs inside a sealed box). I would suggest using the Megasquirt system. Theres a local guy around here who used that system on a Suzuki 1100(which was carbed before) It had a turbo system, and when it was all done it made around 200hp. (Street driven).....now I have no idea how much boost he was running...but you should look into it. I think it costs around $200, and you build it yourself(it comes with most/all the parts), or you can just buy the blueprints(I think....)
