Honda K20 Forged Pistons
Honda K20 direct replacement forged pistons complete with rings, wrist pins and circlips.
These Honda K20 forged pistons are availible in both high compression for normally aspirated engines and low compression versions for forced induction applications.
The high compression versions give a compression ratio of 12:1 to 13:1 while the low compression versions give a compression ratio of 8.8:1 to 9.8:1 depending on the thickness of the head gasket used.
Valve cutouts are specified at stock depth but the pistons have sufficient material to allow these to be increased for use with camshafts with extreme lift at TDC.
All pistons are produced from low expansion aluminium to enable factory bore to piston clearances to be maintained for quiet operation and increased service life.
