ISR Performance O2 Housing for Top Mount SR20DET Manifold

The ISR Performance O2 Housing for the Top Mount SR20DET Manifold is the dedicated O2 elbow built to mate the ISR top-mount manifold to popular Garrett 28/30-frame V-band turbos. 90mm Garrett-spec V-band on the turbo side, 3-bolt downpipe pattern on the back side, and stainless construction throughout.

What It Does

If you're running the ISR top-mount SR20DET manifold (IS-SSHT-NS13) with a modern V-band turbo, the O2 housing is the piece that adapts the turbo's turbine discharge to the downpipe. This one is purpose-built for the 90mm Garrett V-band pattern, which covers most popular GT/GTX 28 and 30-frame turbos. On the downstream side, it carries a 3-bolt downpipe flange that mates to the ISR off-the-shelf SR20DET downpipe (IS-SSDP-NS13).

Fitment

Designed exclusively for ISR Performance top-mount SR20DET manifold (IS-SSHT-NS13) installed in S13 or S14 240SX chassis with SR20DET engine. Turbine housing must be Garrett-spec 90mm V-band. will NOT work with other V-band sizes (e.g., 76mm, 102mm), and will NOT work with V-band housings from manufacturers using different pattern dimensions. Confirm your turbo's discharge V-band size before ordering.
