I have an old school Turbonetics T-Series Journal Bearing. It was cheap and durable from what I gathered from my research. I have been road racing it for a year. I am very happy. When deciding on my turbo purchase, I weighed Garret to Turbonetics. Turbonetics was less expensive, a work horse, and I liked the fact that they had their compressor maps easily accessible online (Garret from what I remember was limited in regards to their published material). I couldn't find any hard core data on response time difference between journal and BB. Is BB a faster spool? Of course. But how much faster is it? Seat of the pants is great, but when another couple hundred dollars is dependent on what, a couple hundred rpms in response, I am indifferent because I am above 4000rpms around the track anyways. Does this spool response matter to drag racers? I'm sure. My .02
