I bought this turbo probably close to 18 months ago back when I had no idea how big was "too big" for our trucks.

I was cleaning out my garage and came across the turbo again, and wondered if i could use it for maybe a twin set up or if its any use to even try to sell, the tag isn't on it, but I came up with a few numbers on it.

Its a Holset turbo, on the compressor side it has a few different numbers: LM25, 7932, 20k4

On the exhaust side it has 3533410 and 22 210 on it

any idea what this is? the intake is 4" in dia. took a few pictures I can post if necessary, its must larger than stock on the exhaust housing, the compressor is probably 1-2 inches larger than the stock hx-35,

Thanks for reading.

 

Yeah - post a pic of that bad boy!

 

HX-55 maybe ?

 

Posted pictures in my gallery, pending approval, I"l bump then if no reply to see if anyone knows what the heck this thing is. thanks.

 

I'll take it!!!

 

Pictures are up now.

 

Looks like a non waste gated HX-40 to me... Could use it to make a hybrid and put it on your truck. Though you would want to find a shop capable of balancing it for you before you do.

 

It looks too big to be an HX40, more like an HX50-HX55 sized turbo. The compressor housing clamps to the center section too.

H2E?

 

I was thinking along the same lines, I've seen an hx-40 before, this is definitely larger than those, maybe I can find a nearby turbo or diesel place, might know what the heck it is.

 

Can you measure the diameter of the compressor inducer?
