If it was a shop in an industrial park, where the technicians wear white overalls and cnc machines in the background, with the engine out of the car, on a flywheel dyno, with two or three wide lambda sensors hooked up to the exhaust (a la german tuners) somehow fills me with more confidence.
Forgive my cynicism, but I have had enough rough experience with barnyard turbo kits. Let's just leave it at that. Sad thing is there are customers out there....

Based on Mark Digrappa's experience and the earlier post he put up on this topic, there are good reasons to assume that any forced induction system will be bad for this engine and shorten its life considerably. But that's just my opinion. I plan to keep my car for a very long time, and I don't want to have to replace the engine any time soon.

I'm still not sure I will go through with turboing my car. I'd give it even odds right now. If I do, I plan to get it finished by the end of July. But I am quite concerned about the cost of the project and the reliability of the engine and drivetrain under boost.

Rick,
What you say may turn out to be true. However, current experience with forced induction and the S2000 doesn't really support what you are saying.
Most of the problems with the Comptech set-up have had to do with vibration, from the cracked head to cracked mountings. These aren't problems of forced induction but of design and balance.
The problem with rear differentials breaking is, most likely, caused by the momentary force of high rpm clutch dropping, not increased torque from the engine. From a design perspective the forces caused by the clutch dropping are at least an order of magnitude greater than the increase in torque caused by forced induction.
Similar engines to this have done well with forced induction. Jackson Racing makes a very reliable system for the Integra Type R and is planning to release on for the RSX as well. (Both high revving, high compression engines.) Granted the type R was limited to 5.5psi, though the RSX system is planned to be 6psi. Volvos wagon has a compression ration of 10.3:1 and it turbocharged as well. Electronics and design are allowing for high compression engines to be reliably turbo/supercharged.
As far as a reduction in longevity goes, only time will tell, though history with mild forced induction (less that 8psi) shows there is often no appreciable decrease in engine life.
