With 10 years of experience, ScienceofSpeed has designed, tested, and put into use some of the most impressive NSX engines. ScienceofSpeed has designed and built engines for applications varying between the street driven NSX to the offroad NSX powered race car.
The factory NSX engine, with careful tuning and a well designed supercharger or turbocharger system is capable of producing approximately 160-180 horsepower over factory power level. Any further, and limits of the factory engine is quickly realized. We offer high performance engines for the NSX to bring it to modern power levels and beyond.
our process: through in house research and development, we have perfected the best formula of component materials and design, machining and clearances, and assembly techniques. Each engine is built in our climate controlled engine assembly room where each component is measured and recorded as a part of our blueprinted assembly process. In addition to the high performance components used by ScienceofSpeed, each engine is rebuilt using all new seals, gaskets, and bearings.
stages are rated by crankshaft horsepower capacity: to help our customers match their power goals with the proper modifications ScienceofSpeed offers three "stages" of engine modification. These stages are rated in horsepower at the crankshaft since power measured at the wheels can vary by chassis dynamometer used. A 15% drivetrain loss factor (the loss of power between what is measured at the wheels & crankshaft) is used for a general guideline. Keep in mind that these ratings are what the engine is capable of producing with the addition of a properly designed supercharger or turbocharger system.
fuel requirements: in our experience, "premium" 91 octane (rated by R+M/2) supports up to approximately 180-200 crankshaft horsepower per liter with a properly designed turbocharger or supercharger system (for example: a 3.2L stage 2 engine would support approximately 640 crankshaft horsepower). For applications requiring more power, a higher test fuel is required.
suggested options: Each engine is assembled with a new factory timing belt. In addition to the options available to each stage, we also recommend considering the following items depending on age & application:
- ScienceofSpeed Lost Motion Assembly Kit
- factory water pump
- ScienceofSpeed Billet Oil Pump Gearset
- factory timing belt tensioner or ScienceofSpeed Locking Timing Belt Tensioner
- ScienceofSpeed Oil Pan Baffle
