I wonder how much more laggy this one would be over the one you have on your car now? Looks like the model you have on the car comes with a 62mm inducer & 88mm exducer rated at ~75lb/min. I in a way understand the flow rates, but I suppose until the turbo is on the car you cant tell what spool will be like.
I have something even better. T366 with a 060 AR housing. 4 bolt to hook right up to your exsisting set up. This should be good for around 750 WHP and will not start working till you have 400 WHP. I was going to go this route but decided that I couldn't wait for the 060 AR housing..... now I wish I would have.
