ISR Performance OE Replacement Turbine Inlet Gasket (4 bolt) - RWD SR20DET

The ISR Performance OE replacement turbine inlet gasket seals the 4 bolt flange between the exhaust manifold and the turbine housing on a Nissan RWD SR20DET. Built as a multi layer steel gasket, it tolerates the extreme temperature swings at the manifold outlet without blowing out the way a cheap paper or graphite gasket can.

A small part that matters

A leak at the turbine inlet lets exhaust energy escape before it reaches the turbine wheel, which shows up as slower spool and a hissing or ticking noise under load. Because the manifold and turbo sit so close to the firewall on an S13, this is a gasket worth replacing while everything is apart rather than revisiting later.

Details

• Multi layer steel gasket
• 4 bolt turbine inlet pattern used by the factory T25 and most T25/T28 style housings
• From ISR's OE replacement range of hard to find JDM gaskets

Vehicle application

Nissan RWD SR20DET, S13 240SX and Silvia, including engines with aftermarket manifolds that retain the stock 4 bolt inlet flange.

Fitting advice

Check the manifold flange for warpage with a straight edge before installing. Replace stretched or corroded studs and bring the nuts up evenly in stages.
