2015 Subaru STi COBB Stage 3 – Turbo Swap – APR Splitter

We did alot of work to this beautiful ride! The customer wanted to go full COBB Stage 3 and was also interested in an aftermarket turbo. We swapped the factory turbo for a Garrett GTX3076R Dual Ball Bearing Turbo. To support the larger turbo and the Stage 3 tune from COBB we added a few more high quality parts. Check out the list of parts below as well as a few pictures we took along the way!

  • Process West TGV Deletes
  • Process West Intercooler
  • Perrin Equal Length Headers with Titanium Wrapping
  • Perrin Engine & Alternator Covers
  • COBB Fuel Pump
  • COBB Fuel Pressure Regulator
  • COBB 1000CC Injectors
  • COBB XLE Diverter Valve
  • GrimmSpeed Air Oil Separator
  • TIAL External Wastegate
  • TEIN Flex Coilovers
  • APR Carbon Fiber Front Splitter

This STi already looks badass, and after all these upgrades its got a whole lot more than looks! Leaving this shop this vehicle had roughly 430 HP 440 Ft/lbs of torque. We built this vehicle to be a reliable daily driver, and with this setup this vehicle will be fast for years to come!

If you have any questions about anything you seen in the pictures above or just have some questions about your vehicle stop by the shop at 980 N Dixie Highway in Boca Raton. Also, feel free to give us a call anytime during normal business hours! We are open Monday – Friday 10 A.M. through 6:30 P.M. and Saturday 12 P.M. through 4:30 P.M.
