Based on standard piston pin diameter.
*1:Crown volume is measured "from the piston shoulder"/"from the deck of the block".
*2:Piston shoulder height is measured from the deck of the block.
*3:The compression ratios given above are only to be taken as a guide, measurements are required.
*4:TODA gasket is required. (Standard head gasket can not be used)
*5:K20A designed using 51.5cc as combustion chamber volume.
