• factory stock & light modified NSX:
  1991-96: factory clutch or ScienceofSpeed Sport Clutch
  1997-2005: ScienceofSpeed Sport Clutch
  comments: if you have an all stock 1991-96 NSX, either the factory clutch or the ScienceofSpeed Billet Sport Clutch is a wise choice. The ScienceofSpeed clutch compared to the factory clutch is less expensive, and offers a lighter assembly for better engine response. If you have a 1997-2005 NSX, the obvious choice is the ScienceofSpeed Billet Sport Clutch, which offers a much lighter assembly for better engine response, and is nearly half the cost of the factory part.
   
• naturally aspirated / supercharger / turbochargers (up to 400 lb/ft - about 475+ whp):
  ScienceofSpeed Sport Clutch
  comments: Although there are several good choices in this range, we prefer the ScienceofSpeed Sport Clutch for this application. The assembly is robust, features easy engagement and a light pedal, and a much more reasonable cost.
   
• high horsepower supercharged or turbocharged NSX (up to 700 lb/ft - about 800-900+ whp):
  ScienceofSpeed Billet Twin Carbon Clutch
  comments: for high horsepower applications, the choice is simple. The RPS Billet Twin Carbon Clutch offers the holding power, but unlike other clutches, also offers a relatively light pedal and much smoother engagement.

1: Torque capacity (at the crankshaft) is a rating of the torque a clutch can hold once under normal operating temperatures and once fully engaged. This number is generally a rough calculation based on the surface area, friction coefficient, and clamping force used on the clutch. It should be noted that this figure is based on the clutch being fully engaged. Note these numbers are manufacture provided and/or estimated values.
2: This is a subjective rating based on the amount of effort required to actuate the clutch pedal in the cabin.
