I have three concerns 1) I had plans to run modest boost 2) I have already tapped to the oil pressure sensor for the oil feed to the head now can I tap from the same place for the turbo feed or is it better to get a sandwich plate 3) I have several cars I can put it in and they all have running motors I have two hatchs eg one is pretty much gutted and the third option is my 2000 Si w/51k
