The factory twin turbos on the RB26DETT run out of breath quickly once you chase serious power. The Garrett GT2860R-5 Twin Turbocharger Set (836026-5005S) delivers a complete matched pair of performance turbos engineered to support up to 700+ horsepower with the right supporting mods. These dual ball-bearing units feature the proven GT Series aerodynamics, internally wastegated turbine housings, and high-nickel castings built to withstand extreme conditions while providing faster spool, smoother power delivery, and superior durability compared to the OEM setup.

Each turbo offers a 47mm inducer / 60mm exducer compressor wheel, oil and water cooling, and a direct-fit T25 flange with approximately 14 psi actuator. This matched pair upgrade gives balanced boost across both banks for reliable high-power RB26 builds on street, track, or drag applications.

At Terra Firma Automotive, we supply this genuine Garrett GT2860R-5 Twin Turbo Set as a premium upgrade engineered for serious RB26DETT performance gains.
