Well since I'm getting scammed out of my 62-1 from SDD, I need to buy a turbo from another vendor. I have the Z7 kit almost done save for some misc gaskets and hardware, and I want a turbo that will bolt on to my 4bolt flange on the crossover and 5 bolt Z7 DP. I'd change the flanges, but I'm just tired of having eveything being changed around and money is tight enough because of this scam. Should I just get another 62-1 from somewhere else? Should I get another brand? I'd like to put down 400whp for now, and eventually I'd like to see 500whp with more supporting mods. An A/R of high .70's, low .80's would be nice, and something that's reliable of course. Any help would be great, thanks.
