Sorry long time no update being busy to rebuild campro engine . something special to share here . First let see what is different between 1.3 and 1.6 campro engine . Basically both engine share same block and head . But 1.6 head slightly different because it is ready cps platform , 1.3 not . Anyway both head still can use .
let see cranksdhaft for 1.3 and 1.6 .
1600cc crankshaft
1300cc crankshaft
Picture below show different of stroke to stroke pitch
Next we will see piston and conrod
1600cc piston and conrod
1300cc piston and conrod
let see different between both piston and conrod height
1300cc taller than 1600cc . Because 1300cc crankshaft stoke to stroke pitch shorter than 1600cc , then it need longer conrod . Basically both piston is same , just different in head top design . sink down and bounce up .
Actually we can use the 1.3 liter piston head to increase compression ratio from 10.0 to 11.0 and above . Some modification need to be done one the 1.3liter piston . Of course conrod still need to use back 1.6liter conrod instead of 1.3liter .
Next will be 1.6 liter high compression modification . Almost done rebuild from 1300 to 1600 .
