Need some help identifying a turbo & exhaust housing off a 4BT

[dieselcruiserhead]

I just scored a turbo off a high mount Ford application 4BT... It is a Holset but looks a little small to be a 1990 era H1C. . Also, it is a reman Cummins so it has been replaced (and as a result it is very tight). . What I am really trying to do is figure out which exhaust housing it is. I was under the impression that all 4BTs had 12cm2 housings, but this looks larger, so I am thinking maybe its an 18??



On the housing, numbers are:

300 on one side



Then on the other:

5519410

18 128



I am assuming because there is an 18 there that's what it is?



On the 16's and 12's I've seen, in a random clearly seperated elsewhere on the housing but this doesn't have it...



On the turbo, the numbers are:

Kit: 3802107

Assmbly: 3522068

Serial: 345897





Thanks!

Have you used a wire brush and brake clean on the inside of the housing? I have a 12 that says 16 clearly on the outside of the housing, but on the inside near the mounting flange it says 12. I would bet it's a 16. Can't help with the turbo though.

Cool I will check, never knew that. .
