If the kit uses a Rayjay turbo you probably should look into getting something a little more modern. You can have a flange for a Garrett, KKK, Mitsubishi, BW, IHI, etc welded to the header, so you can use a much more modern turbo. It would also help you get better drivability.

An overboost switch would not be hard to wire into your system. It is not a complicated device.
not true 81 sc engines are either 9.3:1 or 9.8:1 but ran small ports
