Nissan Turbo Outlet

Are you looking for the right Nissan turbo outlet to take the pressure off your SR20DET engine? Unleash the beast with this ISR Performance 3-inch turbine outlet. This outlet offers a true three-inch opening for efficient turbine exhaust. More air out means less back-pressure on the turbine which will generate higher RPMs and better intake compression. If you’re looking for an easy way to get the most bang for your buck, this is it.


  • True 3-inch Nissan turbo outlet—doesn’t neck down and impede airflow like substandard parts
  • Double-welded inside and out to resist cracking.
  • Brushed finish, so it looks as good as it works.

Note: You will use your existing stock turbine housing studs and nuts.


  • 3 Bolt Flange Thread Pitch - M10 X1.5
  • Bolt Length - 1 3/4in
  • 3 studs 
  • 1 5 bolt gasket 
  • 1 3 bolt gasket

Premium Parts

The ISR Performance 3" Turbine Outlet 02 Housing is a premium aftermarket upgrade. As with any automotive part, always consult a professional if you are unsure of its proper use or installation. Due to the larger, 3-inch diameter, this Nissan turbo outlet may require modification to provide clearance with existing components such as the bell housing or flange. Always check the part’s fit before attempting installation.

  1. Amazing Value

    Posted by Tim Klassen on

    You couldn't really ask for more. The quality is great, o2 threaded in nicely, all holes lined up with turbo studs.
    I didn't have to do any clearancing on bellhousing or flange in my stock S14 JDM Silvia K's but it was really close.
    Great fitment with my ISR downpipe.

  2. great quality, love the weld and the size compared to stock

    I love this turbo outlet, great quality, great fitment. I'm using it on my Tomei 8265 turbo for my SR. I made a comparison between this one and the stock turbo outlet, Go see it in my instagram @holdmydrift so you can really see the big big difference between them. This one is almost 3 times lighter than stock too! And you can upgrade from your stock narrowband o2 to a wideband. Thank you again Isis for making great parts for low budget builders.

    Perfect fitment for my sr20det, cracked mine in half and this replaced it with no problems. Replacing it took like 30 minutes. Great part.

    Opened the box and was pretty impressed with the product compared it to the stock elbow it was larger and a bit shorter so the downpipe can sit a bit higher and wont scrape as much. Im running this on my redtop full isis headers, isis T25 turbo with this Isis turbo elbow and surprisingly it didnt hit my bellhousing had a few centimetres clearance. 5 stars id buy this elbow again.

  7. Do it!!

    It would have been a 5 star rating but ... The elbow is slightly to big to fit. I had to grind some the trans down to get in without rubbing or hitting anything. Other then that it's perfect. Visibly larger then the eBay 3 inch elbow I had and much easier to install.
