Regarding not liking turbos: What I have experienced is that throttle finesse is hard with a turbo because lag happens anytime time you are off the throttle.
Most people focus on the lag from startup until the turbo spools up. This doesn't bother so much, because as others have pointed out, our cammy motor is actually worse than any turbo I've driven in its power curve, although it does not bother me because at the track I've come to be quite good at keeping it in the second cam.
What I care about is the throttle response in say mid turn when you sometime breathe off the throttle and then back on after the car rotates. My 993 Turbo is okay in this regard, but the turbos do spool up and I have to watch out for oversteer when that happens. This doesn't happen with an NA motor, nor with a supercharged motor.
So, the only way I'd buy a turbo track car is if I could test drive it on a track; I bet the number of people offering to let me drive the FF car has just seriously diminished
So far, it seems the K20 motor transplant comes the closest to my requirements. With a Tri-Point supercharge in a close second place (well, probably a tie if you consider the pain in the but factor of do an engine transplant vs. a supercharger/intercooler installation).
