Guess I was wrong, that's not beyond my capabilities at all. I used to build gas Chromatographs using thermal conductivity detectors, also known as hot wire detectors, so I know them well.

All that aside, it doesn't seem feasible to do all the R&D and manifold design work for a simple street car like I have. That monster you fellas created is a whooooole different ballgame. The mear fact that you didn't use ITBs is significant but may not apply to the useful purpose of my car. Your car is a high strung racer while mine is purely street. My car must operate most of the time on part throttle and off boost in traffic situations. Anything that helps throttle response and reduces the perception of lag is a plus. I was thinking that ITBs would indeed be a benefit for a street turbo. Looks like any benefit may not be that significant.

Thanks all for the info.
It looks like there are many schools of thought when it comes to street turbocharging and the 930. Goran, if you (or anyone else reading this) were to build a 930 strictly as a daily driven street car (with spunk), how would you design the bolt-on portion of the engine? Let's say 400HP was your goal and you have to use the stock compression with SC cams. What style exhaust, turbo(s?), intercooler, intake, etc would you suggest to absolutely optimise that 400HP for street driveability? Was the 993tt the apitome of the perfect 400HP street turbo engine?
