From looking at their site, and elsewhere online, almost all the dyno runs suggest a much better low end torque, and pretty much the same top end.
Sounds like it might be good for a laugh, and not too expensive as a test.
Turbo
Flange
Scavenge pump
Oil piping(although you could probably give it it's own system with cooler at the rear of the car to save piping it front to back?)
Intake piping
With AFM I guess you'd have to mount it at the turbo end of the car, so long wiring for that.
Seems pretty cheap to test.
Getting the right A/R looks to be quite different to typical turbo sizing though.
Man, the intake piping looks tiny, on a Z06 they look to be 2 x 1.5" pipes, totally different thinking to the monster piping you see on most turbo 4s... 2x1.5 is close ish to a 2" pipe, but I wonder what they use on 4cyl cars, havent seen one yet.
