Nissan SR20DET O2 Housings and Turbine Extensions

The factory O2 housing on the SR20DET is a known restriction. Our SR20DET O2 housings and turbine extensions from ISR Performance open up the turbine outlet for better spool and top end flow on S13 and S14 240SX builds. Choose from sand cast turbine outlets, 3 inch O2 turbine extensions, O2 sensor adapters, and 3 bolt 70 mm downpipe gaskets.

We also carry a Future Fabrication turbine outlet for the Toyota 1JZGTE VVTi for those running a JZ swap. Match your O2 housing to one of our 240SX downpipes and an exhaust manifold for a free flowing turbo-back exhaust. See all 240SX exhaust parts. Free shipping on orders over $100.
