After sitting with the engine removed for quite some time, Josh brought us his 2013 Subaru WRX to have it brought back to life and made better than ever!
Up first in the shop, starting off with a new long block from IAG Performance featuring a Magnum Closed Deck short block and Stage 2 CNC pocket ported cylinder heads loaded with valve train components from GSC Power-Division, we rebuilt the EJ255 with brand new OEM Subaru gaskets & seals, WRX STI 11mm oil pump, OEM Subaru oil cooler and associated components, OEM Subaru AVCS components, S2 272°/272° camshafts from GSC Power-Division, oil pan and pickup tube from Killer B Motorsport, cylinder 4 chamber cooling system from Getadomtune, fasteners from ARP, equal-length header from Killer B Motorsport, stock location XR ZERO 86HTZ turbocharger from Forced Performance Turbochargers, 84mm turbocharger inlet tube from Forced Performance Turbochargers, MV-R wastegate from TiAL Sport, 50mm Q blow-off valve from TiAL Sport, complete fuel system featuring ID1300x fuel injectors from Injector Dynamics and components from Radium Engineering, IAG Performance, Aeromotive Fuel Systems, and iWire Wiring Services, Flex Fuel conversion from COBB Tuning, Street Series air/oil separator from IAG Performance, along with all the miscellaneous OEM and aftermarket components to bring it all together, all working well with the existing modifications, including a twin-disc clutch from Competition Clutch, an SF air-intake system from COBB Tuning, top-mount intercooler from GrimmSpeed, turbocharger-back exhaust system, and 3-port electronic boost control solenoid.
With the mechanical work wrapped in the shop, John strapped her down to the rollers for Vlad to perform a custom speed-density Pro Tune via COBB Tuning's V3 Accessport. With 93 octane in the tank, and the XR ZERO turbocharger delivering ~20psi, Vlad increased the EJ255's output to 399.55awhp & 343.43lbft! After the break-in period, we're looking forward to seeing this GH back for the Flex Fuel calibration, and for much more steam!
