ISR Performance S13/14 240sx Top Mount Piping Kit

The ISR Performance S13/14 240sx Top Mount Piping Kit is an auxiliary intercooler piping kit for builders converting from a bottom-mount to a top-mount turbo setup on a 240SX SR20DET or KA24DE-T build. Replaces the existing ISR upper and lower hot pipes with new units sized for top-mount turbo geometry, so you don't have to scrap the rest of your intercooler kit when you swap manifold styles.

What It Does

When you switch a 240SX SR20DET or KA24DE-T build from a bottom-mount turbo to a top-mount manifold, the existing intercooler hot pipe routing no longer fits. The turbo outlet is in a completely different position, so the path from compressor outlet to intercooler inlet has to change. This kit gives you the new upper and lower hot pipes sized for top-mount geometry, while letting you keep the rest of your existing ISR intercooler kit (cold pipe, intercooler, hardware, etc.).

Critical Fitment Requirements

This kit is only guaranteed to fit a specific build configuration:

• 240SX (S13 or S14) chassis
• SR20DET or KA24DE-T engine
• ISR Performance top-mount turbo manifold already installed
• ISR Performance front-mount intercooler kit already installed

If you are NOT running an ISR top-mount manifold AND an ISR intercooler kit, fitment is not guaranteed. The hot pipes are routed around the ISR top-mount manifold's specific geometry and mate to the ISR intercooler's specific inlet position. Mixing brands will require custom fabrication.

When to Buy This

You bought an ISR intercooler kit for your bottom-mount build, then later upgraded to an ISR top-mount manifold (like the RamHorn). The cold pipe and intercooler still work, but the hot pipes don't reach. This kit fills exactly that gap.
