The 87-91 13B-T (Turbo II) and 93+ 13B-REW (Twin sequential turbo) cars
have a factory knock sensor that could probably be adapted for your
application.  The J&S knock detection system would probably be appropriate.
 It can watch which rotor face is detonation and vary the amount of
advance/retard for each rotor face on the fly if you use the dual knock
sensors that come with it.  The problem with your application is that these
sensors are designed to work on the 86+ 13B housings, which have bosses for
mounting said sensors.
