I just ordered it from A-spec. Im going with the bigger A/R as Ray Wilson is doing a large street port on my engine. If your going with the T6 frame, then its silly not to have a ported motor to take advantage of it.

You would think a half bp or full out bridge would be incredible with this turbo. But you don't need it thanks to how fast it spools. I got to go for a ride in NXFD's car in Texas. He was running the Magnus kit 42R set to only 10psi and that car was SCARY fast. But very fun to ride in.

I know that NXFD had a medium sized streetport. And the response was a lot quicker than what I expected. It came on pretty early. I honestly can't say when because I was pushed back into my seat.
He showed me a dyno sheet for it that read 390rwhp @ 10psi. I haven't had a chance to get in a car with an A-Spec 42R kit yet so I can't compare them. Hope that info helped a little.
