The Supra gets 87 and nothing else.

The 6.0 ilmor in the MC gets Torco Accelerator which I believe is good for 20 points so would raise it to 89.

What these guys are saying is true about the knock sensor, it will protect the engine and you can run 87. But for better performance run 93. That's exactly what the ilmor manual says.
