I want to increase the efficiency of my current setup (stock) and get about 200 degrees less egt's and be able to move enough air to support 450 rwhp or so. THere are so many turbos! high tech, BD, ATS aurora, GArrett, any ideas? Who makes the most reliable, toughest turbo so I don't have to worry about it grenading on occasional street tire smoking hard drag-type runs, and maybe one day a trip to the real drag strip? I Am looking for more fuel economy when driven responsibly and airflow enough to move from my current 325 rwhp approx. setup to 450 or so rwhp if i go bigger with injectors and a FASS one day.
