I can't figure out what size housing this is, I'm guessing a 12cm but I can't find it stamped anywhere.

Thanks, Aaron

How does it compare in size to the 12 on your truck? The only other thing it could be is the holy grail 14...not sure how the outside dimensions differ between the two though.....Wannadiesel!!!???


If it is a 14 w/g, it looks a little rusty and beat up...I'll give ya 20 bucks for it

I'm guessing its a 12, I got it with an ebay core. I have another truck i'll put it on. there is a 14 in the p/n so I am wishing it to be a 14cm but I am pretty sure its a 12 unfortunately.

It looks like the same physical size as the one on my truck. I'm getting it sandblasted so when I get it back the size is supposed to be cast into the inlet manifold side. I can't see it now its coated with oil.

It's a 12 cm.

Unfortunately Holset was not nice enough to cast the size into all the housings.

darn thats what I figured though.

Look inside the runners from the manifold side, (some wire brushing may be required), there is a size stamped on one side in about 3/8" numerals.
