KS Spec H and F Series Custom Forged Piston Set
Here at KS Tuned we strive to bring you hard to find H and F series products. We are pleased to offer custom Wiseco Pistons for almost any H22, H23, F20b, F23, F22 combo you could imagine when using a DOHC VTEC H22/F20B/H23 VTEC cylinder head. We no longer offer pistons for engines with SOHC cylinder heads. All custom pistons are built to order.
Typical lead time is 8-10 weeks.
To order custom pistons please include the following details in the "notes" field during checkout
Block you will be using (sleeved or stock cylinder walls?)
Crankshaft you will be using
Cylinder head you will be using
Connecting rod you will be using
Desired bore size
Desired compression ratio
Fuel that you plan to use
And of course we are always available to help you at Sales@kaizenspeed.com
Extreme racing conditions demand the strength and toughness that only forged pistons can offer. Compared to cast pistons, forgings are tougher and more durable, and will stand up to the abuse that high performance motorsport applications require. Most castings are brittle, have no grain structure and tend to fail catastrophically when the material yield strength is exceeded. Forgings have condensed grain that is aligned to the features of the part, which produces higher mechanical properties, and resistance to impact and fatigue. Each forging is designed to optimize the strength-to-weight ratio, and maximize performance.
- Valve pocket designs allow maximum flow around the valve, allowing the use of oversized valves and high lift cams.
- Piston crown shapes are designed to promote the maximum intake charge efficiency through a scavenging mixture ‘Cross Flow’ during intake and exhaust valve overlap. More fuel and air equals more horsepower.
- Piston domes are designed for optimal quench during the compression/ combustion cycle, resulting in resistance to detonation and pre-ignition. The end product is longer engine life and increased horsepower potential.
- Precision machined ring grooves with proper orifice/ accumulator volume feature calculated groove root diameters and axial widths, providing excellent surface finish and flatness, maximum ring seal, and minimized blow-by and oil consumption.
