The PT76 GT-Q turbo (whether journal bearing or dual bb) is rated to support roughly 975 flywheel hp when maxed out. You definitely will need the .85 A/R PTE 3-bolt turbine housing to realize that hp level. This turbo is currently the largest turbo you can run in TSE or Turbo Street Eliminator class at the GS Nationals. (Same class I raced in for 5 years) I only wish this turbo would have been available back then as I would have been using it. Not only for the power potential, but I could have also run a tighter converter and made more mph out the back door. I was running a PT74 GT-Q journal bearing back then.
This is a killer turbo, heck, if I had the cheddar I'd buy it in a heart beat.
Don, good luck with your sale, and I completely understand bro.
Keep me posted.
