ISR Performance 90mm V band Flange for ISR & Garrett 3" GT Turbine Discharge

This ISR Performance 90mm V-band flange is the stainless downpipe flange for ISR turbochargers with the 90mm V-band discharge and for Garrett 3 inch GT turbine housings that use the lipped discharge flange. It is made to slip fit over 3 inch outside diameter exhaust tubing, so you can weld it to the start of a custom downpipe and clamp it to the turbo with the matching 90mm V-band clamp.

Details

• Stainless steel construction
• 90mm V-band profile matching the ISR and Garrett GT turbine discharge
• Slip fit over 3 inch o.d. pipe for custom downpipe fabrication

Compatibility

Fits only:

• ISR Performance turbos with the V-band discharge flange, such as the RSX3076 and RSX3582
• Garrett 3 inch GT discharge flanges with lip

This flange does not fit turbochargers that use a standard 3 inch V-band outlet, and it will not work with standard 3 inch V-band assemblies. The GT style discharge has a different profile than a generic 3 inch V-band, so a standard flange will not seal or clamp correctly.

Fabrication notes

Deburr the pipe, slide the flange on, tack it in place while clamped to the turbo so the angle is correct, then fully weld. Order the ISR 90mm V-band clamp (IS-CL-090MM) separately; the clamp is not included with the flange.

All ISR Performance products are designed for off-road use only.
