Water cooled HX-40

[1FAST2G]

Anybody know if the hx-40's are water cooled? I bought one off ebay and its water cooled. Here are some pics.

People will tell you that you don't need it and to block it off, I say run it, it will only help cooling both oil and turbo.

I plan on using the water cooled part. But what I was wondering if anybody has ever seen a water cooled hx-40. As far as I knew they were only oil cooled. And this one looks even diferent with 2 ports on each side for the water cooling.

I have a holset hx-35 on my dodge ram diesel and a hx-40 on my dsm, niether is water cooled. I have never seen a water cooled one. The one on my truck has over 200k miles and is perfect. Just make sure you take the oil from the head and not the oil filter housing.

It is an option, just not one that seems too common. I've seen the ones that have a water cooled turbine housing on eBay too.

is it ball bearing?

Holset doesn't offer any ball bearing turbos, AFAIK.

Please explain.

I already have a HX-35 and I get my oil from the oil filter housing. I have had is like this for a couple of years with no problems

Thank you, you answered my question.

That looks like a hy35 since it has a clamp for the turbine housing. All the hx35/40's I've seen have the bolt on one.

I would say that you run it with the water and oil cooling. I would do this because the water passages in the center cartridge take up space that the oil would be in, so by not running water you are just running less oil you know. So the cooling will not be nearly as good i would think.

With a turbo only setup for oil lubrication, there will be enough space for oil. But for a turbo setup for oil and water cooling you should definetly run both. Just my two cents.

Its a bolt on housing. Thats just how it looks removed.

I work for Cummins.

We have a WHOLE SHELF of nothing but Water Cooled Holset HX40's....No lie

There are so many variations of the HX40 its not even funny.

Here is photographic proof....each of these Green Engines has a Watercooled HX40 on it:

They are 8.3L I6's.

That Twin Turbo 28L you see in the background, runs Twin Holset H2D's.

That is freakin' awesome

That is a pretty sweet picture.

Please explain.

marine turbos, they have water going through the turbine housing
