Wiseco Pistons
Wiseco Pistons: VW Int'l  Market

Includes: moly coated skirts, rings, wrist pins & circlips.
*
Non-coated, not supplied with rings (you can order RINGS separately here)

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.

We're the LARGEST supplier of Forged Custom Pistons and Connecting Rods for the International Import Market. Don't see what you need below? Email us your Piston and Rod needs!

1
Most Wiseco Pistons have an offset pin. Pins must be offset same as OEM for quietest operation.
2 This piston is a flat top w/out valve pockets, to be used if verifying piston to valve and piston to head clearance.
3, B or * = Build to order (custom), 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.
5 There are different versions of this engine - do visual inspection of dish/valve pocket area to verify compatibility.
A = Piston Rings need to be adjusted
B or *
= Will build to order (custom), Non-coated, not supplied with rings.
E = With valve pockets unline K557M series.
H = Based on Volvo rod 23mm. Ford OEM 21mm
R = Pin 20mm, OEM = 20.65mm (13/16)

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.
