  • Precision tolerance CNC machining for quality, repeatability and performance.
  • Crown thickness and ring lands designed for power adders such as forced induction (turbos & blowers) and nitrous oxide. (Note: High comp. pistons are generally designed for nat. aspirated engines)
  • High Quality Piston Rings featuring positive twist nitride steel top ring, Napier 2nd ring, and nitrided rails on a specially designed expander for the best oil control.
  • Wrist Pins constructed of chrome moly steel material for the ultimate in strength.
  • Honed/Reamed pin bore holes for a precise tolerance fi t between wrist pin and piston.

Notes:
* Non-coated, not supplied with rings (you can order RINGS separately here)
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.
