If you plan on using an EFR turbo. Make sure you budget in exhaust temp sensor and shaft speed sensor. It is very important you don’t over speed them or over heat them. If you do that fancy Gamma Ti turbine wheel will turn in to a bunch of pieces.

When I had a customer run them we learned fast. Have spare turbos. Data log the turbine inlet temp and shaft speed. Have safety measures set in your ECU to make sure they don’t over spin or get too hot.

The easier thing to do is just use a turbo with an Inconel turbine wheel.

A turbine failure on the first turbine in the loop could get ugly! That's an expensive day.
