ISR Performance Hotpipe and GReddy BOV Kit - Nissan S13 SR20DET

The ISR Performance Hotpipe and GReddy BOV Kit is a complete charge-pipe and blow-off valve solution for SR20DET-swapped 1989-1994 Nissan 240SX (S13) builds running the factory S13-style intercooler. Pairs the ISR Performance aluminum hotpipe with a pre-welded BOV flange and a GReddy Type FV2 blow-off valve for a clean, install-ready package.

What It Does

The "hotpipe" is the charge pipe running from the turbo's compressor outlet to the intercooler inlet. On an S13 SR20DET swap, that pipe needs to clear the engine bay, mate up to the S13 intercooler, and have a flange for a blow-off valve. This kit handles all three. The ISR hotpipe is 2.25-inch aluminum with the BOV flange already welded in place, and it ships with the GReddy Type FV2 BOV ready to bolt on.

Using the factory intercooler keeps install simple and budget-friendly for a fresh SR20DET swap, while the FV2 BOV adds the characteristic atmospheric vent sound the GReddy is famous for.
