| 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. |
