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.
#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 Non-coated, not supplied with rings.
#4 JDM SR20DET have different chambers based on year - some are Flat Tops and some are Dishes. PICK ACCORDINGLY! All have iron cylinders.
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.
