Stick with the proven JWT turbos man. I am running the 700BB at 24psi all day along and never any troubles. NO BOOST LEAKS AT ALL. You will need the braided reducing oil lines though. Plus grind some of the motor mount bracket but other than that you will be good to go. We here at Knightdale Z only run JWT and we have never had any problems yet with these turbos. Yes they are more expensive and proven. Ever heard the saying CHEAP IS DEER?
