ISR Performance - RSX3582 Turbo

The ISR Performance RSX3582 is a larger-frame top-mount turbocharger built for serious-power builds on SR20DET, KA24DE, RB, and 2JZ engines. T3 flange with a 0.82 A/R turbine housing, dual ball bearing center cartridge, and a billet compressor wheel rated 500-750 horsepower. ISR's larger-frame addition to the lineup alongside the smaller T2 replacement turbos.

What It Does

This is a top-mount turbocharger sized for builds running well past the limits of stock-frame replacements. The 62mm/82mm billet compressor and 68mm/62mm turbine combination, paired with dual ball bearings, delivers strong response for a turbo this size while supporting 500-750 horsepower of usable power. The T3 0.82 A/R turbine housing is the most common housing spec for street and street/strip use, balancing spool against top-end flow.

The 90mm V-band discharge flange on the turbine outlet keeps the exhaust connection clean and lets you build a downpipe without dealing with bolted flanges and gaskets that don't seal under high backpressure.

Critical Setup Requirement

REQUIRES an oil restrictor with a 0.036-inch to 0.040-inch orifice. Dual ball bearing turbos do not tolerate full-pressure engine oil supply. Running this turbo without a properly sized restrictor will damage the seals and cause oil leakage into the compressor and/or turbine. This is not optional.
