ISR Performance KA24DE Top Mount Turbo Oil Line Kit – Nissan 240sx S13/S14

The ISR Performance KA24DE top mount turbo oil line kit gives the Nissan 240SX S13 and S14 a complete, pre-planned set of oil and coolant lines for a top mount turbocharger on the RWD KA24DE. Instead of sourcing fittings one at a time and guessing at hose lengths, you get feed, return and coolant plumbing designed to route cleanly around a top mount manifold and connect to the factory ports on the engine.

How the kit routes oil and coolant

The 3AN oil feed line runs from the oil filter housing, via the included BSPT/NPT block adapter, up to the turbo. A coolant distribution block feeds coolant to the turbo and returns it to the engine using factory ports, with 6AN lines in each direction. For the oil drain, a 10AN steel weld-on bung installs in the KA24DE oil pan and a 10AN GT-style turbo drain flange mates to the turbo, so the return is an unrestricted gravity drain.

Fitment

Nissan 240SX S13 and S14 with the RWD KA24DE, using most top mount turbochargers.

Before you install

Clean every factory oil and coolant port before connecting the lines. Sludge, debris or corrosion in those passages can restrict flow or push contaminants straight into the turbo bearings, which is the fastest way to destroy a new turbocharger. This line kit is designed to pair with the full ISR KA24DE top mount turbo kit for a complete bolt-on system.
