Hi Darwin, do you already have an idea about the next turbo?

Not sure what era your turbo is from, but John updated my original VR5 (circa 2008 originally) and it really opened up the top end, I swear with less lag. Progress, what are you going to do..... Not sure if he's still doing them (?), but that might be an option vs an all new turbo.

Looking at the 3076R series as a replacement. I have a friend who is going to help me fab up the necessary exhaust components to run the v-bands and such.

Mine is from 2011. I didn't really know that was a service ever offered, but the turbo has already been rebuilt once. Ever since, I've struggled to keep oil from getting burned through the turbine housing. The turbo performs great, just figured if I was going to yank it out again, I might try updating to BB and v-band.

The GTX3076R 0.82 I ran on my 8V engine with the stock intake gave the most punch in the mid range.

That is the EXACT turbo that I’m trying to get!

Darwin, turbosmart make an oil pressure regulator for turbos that restricts pressure but not flow, which may be of use with your older turbo with oil getting forced into housing and burnt
