Very clean Suburban we had the pleasure of doing a build on. Customer wanted more power & still be reliable for this big family hauler. We started off with a Brian Tooley Racing stage 1 turbo cam. Reached out to Huron Speed Products for one of their turbo kits along with our good friends over at Comp Turbo Technology. This is running a 76mm oilless air cooled Comp Turbo Technology. For the fuel side of things we kept it more simpler, we added a single 525lph pump along with a set of Fuel Injector Clinic 1000cc injectors. Supporting the new 200+hp & tq is a PerformaBuilt Transmissions Black Edition 4l60 along with a Circle D Specialties triple disc converter.

On 93 it put down 558whp & 546tq. On E85 it put down 622whp & 592tq. This should make hauling the family around & getting groceries more enjoyable!
