and the price of GT35BB's are up there. When I sell my NA engine I'll be in the ballpark for some TD04's or something similar. I broke the engine in with stock rebuilt turbos because it was economical. How much did you pay for your GT35BB's? I bet it wouldn't suprise you if I were to tell you I have access to ceramet bearings and the equipment to upgrade my own turbos.. I'm all about the economy of this hobby and I enjoy doing things myself. So what if I used stock turbos on a brand new engine... :) I'll get into the 11's with them. What you running with them BB turbos?
