ISR Performance Ball Bearing RSX2860 Turbo - Bolt on cover

The ISR Performance RSX2860R is a dual ball-bearing small-frame turbo built as a bottom-mount upgrade for SR20DET and KA-T builds replacing the factory T25 or T28. Billet compressor wheel, bolt-on compressor housing, and the kind of spool-and-flow profile that earns its keep on a daily-driven build that still wants to make real power.

What It Does

The factory T25 on the SR20DET runs out of breath fast once you start chasing real power. The RSX2860R steps up to a dual-ball-bearing center section, a billet compressor wheel for better transient response, and a bolt-on compressor housing that makes intercooler-side piping changes easier. All ISR turbos ship with dual step gap rings and are balanced to OEM specifications.

Fitment

Designed as a bottom-mount upgrade for SR20DET and KA-T builds replacing the factory T25 or T28. Requires an oil restrictor (.036"-.040") for ball-bearing operation. see our IS-OR-3036 oil restrictor. Oil drain uses the GT-style flange. see our IS-GTDRN drain flange with integrated 5/8" male neck. Oil feed thread is 7/16-24.
