Automotive modification

Engine oil pump



1.6 liter head . You will notice campro got combustion chamber that not really deep . That will allow small bore too be used . Pro is you can build a very high comp campro , con is changed to high lift cam you need to modify piston head . If not valve will hit piston head . That is the reason why matspeed not increase lift but increase duration




1.3 & 1.6 block . Same !!




1.3 liter nothing different with 1.6



campro cam shaft lobe . Measured lift at 5.8 mm . Further increase lift will hit piston head !! . Piston head need to do so mod job to avoid from hit valve .
