ISR Performance Nissan KA24DE Turbo Downpipe - Nissan 240sx S13/S14

Turbocharging a KA24DE with SR style parts creates a known clearance problem: an SR downpipe is a little too short on the KA, leaving the pipe aimed at the floor pan. The ISR Performance KA24DE turbo downpipe for the Nissan 240SX S13 and S14 solves it with an extended 3 inch stainless steel design that clears the floorboard without hammering or cutting the chassis.

Which setups it serves

• Bottom mount KA-T builds using SR style T25, T28, GT2871 or other GT discharge turbos with an SR O2 elbow
• Top mount KA-T builds using the ISR Performance top mount manifold and ISR O2 housing

In both cases the downpipe connects to the O2 elbow or O2 housing on the turbine side and runs back toward the exhaust, with the extra length positioned where the KA needs it.

Important

This is not a turbo back downpipe. It still requires an SR O2 elbow or the ISR top mount O2 housing between the turbo and this pipe.

Specifications

• 3 inch diameter
• Stainless steel construction
• Extended length for KA24DE floor pan clearance
• All gaskets and hardware included

Fitment

Nissan 240SX S13 and S14 with a turbocharged KA24DE.

A 3 inch downpipe pairs naturally with a 3 inch catback such as ISR's GT Series or Series II systems for the S13 and S14, giving you a consistent diameter from the turbine to the tip.
