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.
Our naturally aspirated engine program is intended for customers who wish to repair their existing engines and retain factory specifications - and for customers who wish to maximize power naturally aspirated with out the addition of superchargers or turbochargers.
about naturally aspirated tuning:
The factory NSX engine is fairly well tuned from Honda with 270 hp / 3.0L (90 hp/L) and 290 hp (90.6 hp/L). While the gains from naturally aspirated tuning is generally lower than forced induction tuning - naturally aspirated engines can offer increased power and throttle response.
Naturally aspirated gains can be achieved in four ways:
- increasing induction efficiency
- increasing exhaust efficiency
- increasing displacement
- increasing pressure & energy use in cylinder
With these engines, ScienceofSpeed recommends a high flow induction system, header & exhaust system.
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.
engine management requirements: ScienceofSpeed recommends programmable engine management systems for all engines except engines that are built to factory specifications (3.0L or 3.2L).
fuel requirements: the compression of the engines can be modified based on the fuel used. "Premium" 91 octane (rated by R+M/2) is recommended for engines up to 11:1 CR. For compressions above 11:1, a higher test fuel must be used. Compressions can be increased for applications that will allow high test race fuel or alcohol blended fuels to be used under all conditions.
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
