S500 compressor housing
 

I have a 3837221 borg warner turbo which is for a d16 industrial engine that I want to put on my 3406e 15.8l cat. The problem I have is with the compressor outlet. I'm needing a comp cover to where I can use my stock elbow to intercooler or a elbow for my cover. I've searched for an elbow with no luck.

I'm assuming the cover just has the hose discharge? You can get silicone elbows that go from 3.5" to 4", or whatever size you have. I'm currently in the process of putting a s478 on my 3406b but the comp cover has a vband that I will probably weld up an elbow for it.

No this cover looks just like the cat one where you use 2 orings and 2 tabs that bolt on to hold it in but smaller in diameter. Measures like 3 3/4” where the cat cover measures 4 1/2”.

Those outlets are very interesting looking. Always wondered how that worked. Makes more sense now. Can always chop that willy wonka thing off and have a vband welded on.

Yes what he said! Or find a junk cat turbo and cut and swap the comp outlets maybe?

So I had my buddy widdle me up this bad boy, cat outlet with a s400-s500 vband on the back side. I dont have it in the truck yet but I think its going to work slick!

Order the older cat elbow for the early B model engines, the o-ring setup on those is 3.75".

Could have used an elbow from a C12, N14, or ISX for it to work, or bought the right 478 with the cat style housing.

For $600 I couldn't say no...
