All the NA 1.6 pistons pre -86 are the same, carb or injection. Post -86 injection models also use the older type "hemi" piston. This pistons have the raised crown on both sides of the pistons.
The post -86 carburettor engines use the lean burn head and tehy only have the raised crown on one side of the piston.
The third type of 1.6 CVH piston is the low compression turbo piston.
