Patterson, if you are so confident in Ebay turbos then go boost one to 30+ psi and see what happens. Good luck...

Another thing, Precision uses certain Garrett hardware, as well as Garrett wheels in their turbos. But yes, it may be true they build their own CHRAs.

The new 'S' series Borg Warner turbos are made with a CHRA and wheels designed by Borg Warner themselves. That's why you see the ETT in Borg Warner turbos, not in Garrett's.
