I have no idea what size turbo to use with this setup. I want a turbo that will give me the 250whp that I'm looking for, without endangering my motor. If there are any weak points in this setup please feel free to chime in. What brand turbo's are reliable? What size should I look for? (I know it has to be t3 flanged)
