ISR Performance Ball Bearing RSX2860 Turbo

The ISR Performance RSX2860R is a small frame dual ball bearing turbo with a T2 flange and .64 AR turbine housing, built as a top mount upgrade over the factory T25 or T28 on the SR20DET and KA24DET. It brings ball bearing response and a billet compressor wheel to a budget well below a Garrett GTX2860, with balancing held to OEM specifications.

Fitment

Top mount T2 flange applications on the Nissan SR20DET and KA24DET, replacing the stock T25 or T28 turbo.

Required for installation

An oil restrictor of .036 to .040 inch is required (part number IS-OR-3036). Ball bearing turbos need the restricted feed; running without one can push oil past the seals. Use the GT style drain and keep the drain line as vertical as possible.
