Crank angle sensor

Okay guys heres the deal. I have a S5 Rx7 with S4 T2 block, S5 manifolds, s5 turbo, pretty much everything s5 except the core, and J spec S5 T2 ecu.

Which crank angle sensor do I run? S4 or S5? I already heard that N/As don't work because when the turbo spools the timing advances. Any info would be of great assistance. Thanks.

As boost builds you need to pull timing. If you were to advance it under boost than you will blow up the motor.

Either way, the CAS has nothing to do with the timing advance/retard. It only sets base timing. Once the base is set, the ECU does the rest.

The parts catalog only lists one part number for S4 and S5, turbo and non-turbo. I would conclude from that based on this, they're all the same.
