Honda / Acura delalers never sold any turbo kits for the NSX, only superchargers.
There is no such thing as
factory installed supercharger, Acura
dealers offered Comptech superchargers. My car came with the CTSC that was dealer installed when the car was new and the warranty was never cancelled.
Many buyers were shown a Comptech catalog from which they could add additional options for their cars like a supercharger, headers, cat back exhaust, coilovers, brembo brakes, air filter box, targa compartment, anty sway bars and many more. Some didn't buy anything, some bought just the SC, some the SC + headers and exhaust and some went all out and bought everything. Many owners will say that they have the "Comptech package" but the truth is that each car may have different amount of upgrades so each "CT package may be different". My car came with the CTSC, CT headers, CT exhaust, CT sway bars, CT carbon fiber air filter box and CT targa top compartment.
I hope that helps, more on the topic:
