Everyone's saying the 1.9 intake with the "D" ports will fit a 1.6 head.......yes, it will physically bolt up, but the 1.6 head has oval intake ports.....you will need to enlarge your 1.6 ports to match. I have no idea if there's enough meat there to do that. Seems to me there is, I think I remember a few guys on this forum doing just that.
