Wiseco Pistons - Subaru
Includes: moly coated skirts, rings, wrist pins & circlips.
*
Non-coated, not supplied with rings.
Wiseco is world renown for their work building race winning
pistons for compact engines featuring small bores, multi-valves, and
high RPM's applications for many years.
Features:
- Stocking Pistons now come coated on the sides from the factory
- Valve Pocket designs that allow max flow around
valve, also allowing oversized valves and high lift cams to be
utilized.
- Piston crown shapes designed to promote max
Intake Charge efficiency thru scavenging mixture 'Cross Flow" during
intake and exhaust valve overlap. More fuel and air equals more
horsepower.
- Pistons designed to optimize squish or quench
during compression/combustion cycle event, resulting in resistance
to detonation and pre-ignition. The end product is longer engine
life and increased horsepower potential.
- Complex piston skirt profiles that reduce power robbing
friction, yet promoting stability in bore for optimum ring seal.
- Precision machined ring grooves with proper orifice/accumulator
volume using calculated groove root diameters and axial widths,
featuring excellent surface finish and flatness providing maximum
ring seal and minimizes blow-by and oil consumption.
- World class forging facility that utilizes the latest
technologies featuring complex forged shapes, advanced materials,
and featured aligned grain flw technology.

Notes:
#1 Most Wiseco pistons have offset pins. Pins must be offset the
same as o.e. for quietest operation - Pin offset will be opposite of
direction of engine rotation.
#3, * Non-coated, not supplied with rings.
Notes: that apply to all Part #'s:
* Some pistons are listed with a range of compression ratio's.
The low number is determined w/an un-cut deck and the high number is
determined w/.030 piston to cylinder head clearance.
* Always check pistons to valve clearance -
If using VTEC or like mechanisms- check w/longer duration higher lift
lobe.
* Always run at least .030 piston to head
clearance including gasket thickness.
* If piston appears to be different than
expected, please do not hesitate to call Wiseco at 800-321-1364 to
verify proper installation specifications. |
