Im going straight to L20b crank, extra bolt for rear of crank and with 85mm stock ca20e pistons milled 1.75mm and L14 conrods.
Piston comp height will be down to 28.25 from 30mm plenty of meat left and gives good rod stroke ratio and 1952cc.
Much lighter pistons than 38mm original heavy L slugs so will rev awesome and extra economy.
