Doesn't sound too hard. I know that those bed bolts can be a real pain.

I want to do this turbo swap bad... I'd rather have a holset or schwitzer instead of a garret.

 

Farm, I want those answers too. I have a Holset HX35 sitting on my shelf. I was wondering what it would take to put it on. I actually have a motor sitting on a stand with turbo and all. I could use that to mock it all up. But if I remember correctly, didn't Ryan Bean say they spin backwards of our Garret? I thought he said something like that.

 

Some many question.. so little answers.

I guess we have a good start to our long journey. Have an engine on the stand would definintely be easily to make up some type of bracket and help troubleshoot.

I'm not sure what way they spin, but I don't see how they can spin backwords. Maybe the whole "unit" it turned around? If that makes any sense. I'm sure it doesn't lol.

 

I think I'm gonna PM him and see if he'll get on here.

 

Sweet.

They way I look at it... I could start with the HX36. It surely can't take much work to modify that to move up to a hx50.

 

I can't find his name on here now..... I'll just email him.

 

yes our stocker is a reverse rotation (exhaust comes over the top) The Holset and nearly every other turbo out there is standard rotation (exhaust comes in from the bottom and around. Its really no problem. Just look at the pics I posted and you'll see what I mean on how the exhaust housing is situated.

As for lighting the HX50 I won't be running it until my stage 2's are installed and running. I have heard of few guys running a 17cm housing on chipped super duties but on a OBS truck you need at least 1's to light it and even then it might be pretty laggy.

As far a HX35 or 40 I really think they will be too small for the PSD. They also use different exhaust flanges so you could build up a kit for a HX35 then if you outgrow/don't like it drop in a 50. I am quite confident with stage 2's lighting the HX50 won't be a problem. Even if I went to a 19cm exhaust housing. I think it will be great combo but time will tell. I will do have a full OBS mock up motor now so I am gonna plot the aftermarket downpipe position for the stock turbo then building up the kit from there.

 

Good call TJ. Maybe you should move this up on your list??? lol

I looked at those pictures too. Anything is possible with a: Mig welder/plasma cutter/case of beer/lots of vacation time.

Seriously though, this would be a heck of a combination. I wonder what power this this thing could put out?

 

I think with 2's, turbo and programming I think 400 would be easy.

 

So here's kind of a list of things that would have to be done...

Figure out how to get a 4" DP in there (most likely a body lift would have to be done)
Fab up a custom Pedistal bracket
Fab up adapter for up-pipes
Remove wastegate because of clearance issues
Most likely re-do intercooler piping
Most likely have to figure something out with the intake pleums

I think all in all it would be cheaper than doing a D66, depending how valuable your time is. I see on Ebay you can't get a hx50 for $220. However, the seller is from China. Probably not the ideal place to find one.

 

What about using a HX35 as the smaller in a set of compound turbo's??? I know that gets alot more complicated, but sounds to me like it would work, seeing as how it came off of a six cylinder!

 

It was dicussed early that they have smaller exhaust housings compared to our stocker. It would probably work though. They are a dime a dozen nowa days.

 

Yes don't buy from the China seller. He looks fishy!

Also I don't think a 4 inch DP is needed. It would be nice but not worth the effort in my book. Also not all HX50's come with a wastegate. The one I bought did but that will be easy to build a block off plate if it doesn't fit in there. The intake plenums will be fine as is as well as the cold side pipe but the hot side pipe will need some rework to meet the turbo. Also a air filter tube will need to be built as the turbo has a 4" inlet and is sitting straight across the engine and not at an angle.

Twin turbo's are way more than the average or even above average joe wants to get into. Just slapping two turbo's together doesn't work that great and with room availible under hood many of the twins I have seen on PSD eliminate the HVAC box. Not all of them but many of them.

 

So does anyone know what engine or application the hx50 comes on?

Where would be a good place to start looking?

 

Its used on larger Cummins engine but I can't recall which ones. They will be big though. over 10 liters 6 cylinders.
