ISR Performance M-Spec Intercooler Kit - Nissan SR20DET S13

The ISR Performance M-Spec intercooler kit for the Nissan S13 SR20DET is a full front mount package: core, every aluminum pipe, and the hot pipe that most competing kits leave out. ISR built the core to the same dimensions as the discontinued Greddy M-Spec, a size that has long been the go-to for S13 owners because it fits behind the bumper without major cutting while supporting approximately 400 horsepower.

Core Specifications

• Core dimensions: 276mm high by 600mm long by 76mm wide
• Bar and plate construction
• Identical sizing to the discontinued Greddy M-Spec core
• Designed to support approximately 400 horsepower

Why This Kit

• All aluminum piping, no rubber or silicone pipe sections to swell under boost
• Includes all piping needed to bolt up to the S13 SR20DET, including the hot pipe from the turbo outlet
• Core sizing that is known to fit the S13 front end

Fitment

Nissan 240SX S13 chassis with the SR20DET engine. Piping is routed for the SR's factory turbo position and stock intake manifold throttle body location.

What's Included

Bar and plate M-Spec sized intercooler core, complete aluminum piping set, and the hot pipe. Hot pipe variants pre-flanged for HKS or Greddy style blow off valves are available separately if you prefer a specific valve.

Install Notes

Remove the front bumper cover for access, hang the core first, then work the piping from the turbo forward. Tighten clamps only after every pipe is seated so the couplers are not under side load. Pressure test the system before the first boosted drive.

All ISR Performance products are designed for off-road use only.
