Getting thread back on track.......Pure have a strong reputation for quality. It will be interesting to see how the cast setup effects power delivery on E85 and higher boost. Looks like it wont be far off the orignial stg2s. My car has had Stg2s on for years. Stage 2's have enough power potential to run 131+mph terminal 1/4 mile, in a full weight AT car at 24psi. Enough to break lots of things. To be honest the cost of supporting the power these turbos can make is many times the cost of the turbos , regardless of which brand you get. I think alot of these threads are spending too much time on which turbo/s (its like some sort of weird N54 owner hang up) and not enough on what is actually the goal. Want to run 10s 1/4 , 180+mph 1/2 miles , roll racing or cut crazy track times, you will need to figure alot out.
