ScienceofSpeed Billet Stroker Crankshaft |
| |
|
Advanced custom designed billet steel
stroker crankshaft replaces factory 78mm stroke crankshaft with a billet
crankshaft allowing an 86-88mm
stroke for an increased displacement of 3.4-3.8L. Designed specifically for
the NSX block using Honda NSX main and
connecting rod bearings. Precision cut and dynamically balanced.
Proprietary bob-weight design for minimal friction loss. Maintains
factory oiling system for journals. Bolts directly to factory crankshaft
pulley and flywheel. Bearing selection and block clearancing required
for installation. We recommend a capable engine assembly facility for
engine building. ScienceofSpeed offers a complete in-house custom engine
program. Please

In conjunction with the billet crankshaft,
a custom piston design was developed to maintain a rod ratio as close to
factory as possible with the increased stroke and reduce rotating mass
as much as possible for high RPM performance and durability. Rotating
mass of EACH piston set and connecting rod drops nearly 100 grams in total
over factory components. This piston includes a special high strength
lightweight piston wrist pin that is compatible with the factory
connecting rod for naturally aspirated engines. Turbo/supercharged
induction engines will require a custom billet connecting rod. Piston
available in 90-95mm diameter & various compression ratios.
