For stock frame turbos wait for the RB's to come out. Cheaper and they will fit better on the turbo. The VTTs really have to be clamped down on the turbo to prevent leaks. Yes I saw Tony's video but the reality is much different when you're installing them on the car. If they were smart they would have made two different kinds, one for stock frames and one for their stage 2 turbos. Get in on the the RB group buy.
I wish I would have waited a couple months for the RB's to come out. But the VTT inlets are already in and there is no way I'm doing that install again
