Vr , Vs ecotech

[Bog6on]

G,day all, i am trying to find out besides the obvious is the vs ecotech v6 the same as the vr v6. I am mainly trying to find out if the heads and bottom end are the same, and any other differences.

Thanks.
Luke.

no the ecotec and the buick v6 are different enough that they are not interchangable.
