We also offer these housing machined to HX40 outlet or 3" V Band outlet. Keep in mind, these operations are machined features and not welded features like other shops offer.
Ceramic coating is available. While the ceramic coating is definitely not needed, it does help reduce underhood temperatures. Please note that ceramic coating is done after the order is placed, so please allow extra time to get the part(s) coated.

7.3 Powerstroke does run much better with a smaller housing. The 366sxe with .91 was a great option that had instant satisfaction. This .83 housing improved it even more. A great improvement across the board.
Great product! Fit and finish is perfect. I used the divided .83 turbine housing that had been modified for a 73mm turbine to replace the .91 housing on my s366. I have this installed on a 7.3 Powerstroke. Spool time improved by about 250-300 rpm. This takes the truck much more enjoyable to tow with. Highly recommend.
