ISR Performance Stainless Steel 3" O2 Housing - Nissan RB25 Swap (Uses SR Style Downpipe)

ISR Turbine O2 Housing - Nissan RB20/25 Swapped 240SX

When swapping a RB20/25 engine into a S-chassis the factory turbine o2 housing interferes with the LHD steering column. The ISR RB turbine outlet is designed to have maximum exhaust flow while still clearing the steering column when using the ISR swap mounts. This housing also allows the use of a S-chassis SR downpipe (When you install the engine using our swap mount set) to mate to the existing S-chassis exhaust system components.

This unit includes gaskets for turbine and downpipe. Includes 3 studs and nuts for downpipe. Does not include hardware for the turbo.

New brushed finish
