This will show the progress in installing the he351ve into my 2nd gen cummins.  I will update as I go along.   This thread is not dealing with the controller needed for the he351ve.  The thread that covers the controller can be found here

You will need some way of attaching the hotside intercooler tubes/boots to the turbo since the output from the Turbo faces forward rather than down like the 2nd gen turbos.  

 

I went with the charge tube from Stainlessdiesel.com HERE

 

You will need a  2.75" to 3" reducer and clamps for this to work.   

 

There are also reports that a 45* reducing elbow will work also.  unsure on that but you can try.

First Specs on the Turbos

 

HX35 56/60/12 60ish lb/min left vs HE351ve 60/68/3-25 right 69ish lb/min

 

 

 

Start pulling the old turbo off

 

Use PB blaster or similar on the flange bolts for a few days prior to removal.

 

Double nut the two bottom studs and remove them so you can bolt the adapter flange to the manifold.  The short bots go in the bottom and the long bolts with the nuts attach the holes of the flange.

 

 

Next if your truck is like mine (auto) there is a hard coolant line just behind the exhaust manifold that will block the rear most bolt on the adapter flange from being used.  you can see the bolt hole in question.  

 

Use the 5/8"coolant hose and a 5/8" T fitting to remove the hardline and replace it with the coolant hose.  You will need to run this to just in front of the oil filter and also to the output of the coolant line from the HE351ve.

 

 

 

 

Next you need to remove the old downpipe if you don't already have an HX40 style installed.    this is a PITA to say the least.  I had to cut mine out.  The hx40 style downpipe flange will attach to the back of the he351ve without the elbow.

 

In order to allow for a more vertical position of the center section I cut off the top of the strut nut.

 

  

 

Center Section installed and coolant hose run to the turbo.  I still need to run the return to the hot line, but I need some more hose.

 

I used a sawzall to cut the flange off the Oil return tube.  I will use some oil rated hose to connect the turbo to the return line.  You can see in this picture that I just reused the OEM banjo bolts for the coolant connections.  I used a hack saw to cut the braided section off so it was just a solid metal banjo bolt.  I then just pushed the 5/8" coolant line over and used a hose clamp.  I will do an fittings at some point, but for now this will work.

 

 

Once the center section is installed,ensure you have removed the alignment dowels from the compressor housing so you can clock the compressor like so

 

 

Use the preferred method of connecting the charge pipe, I choose the stainless diesel pipe and a 2.75" to " reducer then reused the oem 3" to 3.5" elbow at the intercooler.   Alighn all boots and tighten down the clamps.  

 

Note the position of the passenger side neg battery cable to the engine block.  I might have to redo this with a new longer cable, I have been meaning to anyways, but I haven't gotten to it.

 

I used a pfe 5/8" hose to replace the hard metal oil drain.  There is a larger diameter coupler near that block that you can insert the pfe hose into and clamp down to retain the drain connection to the block.  

 

 

Hard to see in the picture but run the other coolant line into the bottom of the turbo and T into the other heater core line.  Ensure you leave some space between the exhaust manifold and the coolant hose.   You might use zip ties or something similar to hold the hoses together.

NEAT! I think the VGT is the way to go...at some point i want to address the restricted exh. housing on my 04.5 ram & this would be a sweet turbo [or simular], the brains to run the vanes is what is the bugger.

 

 great article!! 

 

can you remove the silencer ring?

Nope gonna leave it in as it is part of the compressor housing.  

 

I did hit a snag, I cannot find a machine shop that is willing to machine out the compressor housing so I am going to post the he300vg housing on ebay (correctly unlike the guy I bought it from) and try to get my money back, shouldn't be hard as I didn't pay much for it.

well I just bought a new intercooler pipe $100 shipped

That will allow me to run the turbo the intercooler.  

[organicfarmer]

What!! leave the silencer ring in?!      You must have lost to much sleep!  

My theory has been; TURBOS ARE MEANT TO BE HEARD, BRO!

I have a hearing aid to the tune of 3K out of pocket expense and hearing loss that say otherwise resulting from listening to loud engines over the course of my life running them and both working on and around them.

[Me78569]

yea I don't care to hear the turbo much anymore.  

 

That and you have to machine the ring out means I am not going to do it haha.

I'm actually looking for a silencer ring for my HX35... I'm looking for quiet performance. Loud is easy...

[Me78569]

an hx35 without a silencer ring is enough to drive a person crazy while towing.

Exactly. I growing tired of the whistling whine from the turbo.

[organicfarmer]

I AGREE the hx35 is TO loud [i never had a ring in mine]     NOW i have a quiet cr cummins & i just HAD to take the ring out so i could hear the turbo! just about right!   

While i like diesel/turbo sounds, i always wear ear plugs when i'm in the field on my open station tractor, not as wearing on me 

 

IN REPLY TO ME---i see;, yes, if ring is part of housing.... yup! leave it in... no worries, just me    ....having fun 

 

IN REPLY TO WILL BILL---3000 $         wow! do your stuff , my wonderful earplugs!!!!!

 

Ok ok ,...i confess...when i put a turbo on my tractor the muf. didnt fit anymore... strait pipe!...but not for long!       to much of a good thing!

Really? I have 2, one from my hy35 and one from my wh1c. I believe they're both 56mm, if that even matters.

At 10psi my 98.5's turbo got on my nerves!   [no silencer ring]

First post updated.

[hex0rz]

This will be nice to reference once I start my swap...

[Me78569]

First post updated.  Only waiting on injectors now.

[Me78569]

Sweet injectors should be here on Thursday.  I can't wait to get the truck back on the road.

[Me78569]

Injectors got here a day early to they are in.  Now I am only waiting on the new grid heater gaskets before I can get it all back together.    Getting excited to fire her up.

[Me78569]

Truck is back together. Runs good. Gotta do a little more code work.

[hex0rz]

Oh exciting! Can you make a YouTube video? Id like to see it in action. If I don't have a controller, couldn't I utilize the turbo by fixing it full open until I did? At least I could run it until then... You know. Btw, where's the pictures?
