Before the search ***** smell blood in the water...yes, I've tried.

I'm looking for info on which Holset turbos were used on which generation/year/etc. of Dodge Cummins pickup. I have 2 for an O/T "smokeless" project, and found out they are not the same. I've heard HX-35, HY-35, HX-40... but don't know which is which or where to look.

Thanks in advance

 

hy35w were used on the 98.5-02 autos
hx35w were used on the 98.5-02 manuals
I've got an 01 and researched that far
I think 03-05 autos have the hy35w also don't know about manuals
Hope this kinda answers some of your questions

 

Found this: http://www.myholsetturbo.com/images/...mbers_2008.pdf

...but it doesn't seem to explain why there are a LOT of part #s but very few models.

 

Any ideas which is what here? I'm told the larger one came off an 05, but it's not the same as my 04...

Thanks
