Turbo questions

[RickM]

1: Does anyone know which Garrett turbo is used in the Protomotive 3.2 set-up? I believe it's a T04, but I was curious as to trim. Compressor and Turbine A/R?

2: During some surfing I found that tuners are using the APC knock sensing system off the Saab turbo. They are fitting them in aftermarket turbo installations to engines with no knock sensing capability. Has anyone considered using this in a 911 turbo project?

As always any insight is appreciated.

Rick, Perhaps this should be on the Technical BB. Michael
