Wiseco Pistons - Mazda
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:
  1. Stocking Pistons now come coated on the sides from the factory
  2. Valve Pocket designs that allow max flow around valve, also allowing oversized valves and high lift cams to be utilized.
  3. 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.
  4. 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.
  5. Complex piston skirt profiles that reduce power robbing friction, yet promoting stability in bore for optimum ring seal.
  6. 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.
  7. World class forging facility that utilizes the latest technologies featuring complex forged shapes, advanced materials, and featured aligned grain flow technology.
Piston prices marked with an * do not include rings.

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.
#4 This piston made w/stock compression height, which is very close to cylinder head. Use Cometic thick gasket if decking block.
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.
