I'm not sure if this is an exact fit, but he's a known rotor head and has a dyno. (He also built Price's uber Miata but don't hold that against him). Reach out to Bret DePedro at RP Performance at Summit Point: http://www.rpperformanceracing.com
Flatout Motorsports near Boston has a Dynapack, and are well-versed in the 13B. They used to motor a fleet of ITS 2nd-gens, and they built the STL 13B-powered Miata that's kicking tail up here.
