The other REALLY BAD part about the Precision turbos, is that the manufacturer blamed any/all issues on "oil contamination" which I always thought was complete BS. COMP on the other hand repaired issues at no cost, even when it was an install error.

I have a Precision 6266 with a brand new scavenge pump in stock, as well as a COMP 6767. The COMP is what I'm putting in my car with the build this winter.
