Bump this thread!

Anyone running an hx35g? I recently aquired one. Anyone with insight on how to hook up the cooling lines to the water cooled center section?

You mean HX35W? http://www.myholsetturbo.com/modelinfo.html

I have an HY35W and a HX35W both are oil only. Never seen a water cooled CHRA on a Holset, not to say its not out there.....

What are you using for the VGT controller? Did you set it up as a pneumatic actuator or did you use a PIC and make your own controller?

I thought that was an error. Thought it had to be a CW. Your an animal thats a big ass turbo man, 45lbs, hope your supporting that thing to death. I got one on the shelf and have been thinking about it once I find the top end of my CW. Still cant find a good controller and thats been holding me back as well. Ill use a stand alone WG controller if/when I get around to it if no one has come up with a good controller when the time comes.

I think this is a first for this turbo on a EJ, as far as I know anyways.... Great job, hope you can get the VGT working right.

vgt is not currently hooked up, just locked out, ill need to refab my up pipe now, because ive changed my mine on how ill control it. i want to reuse the factory VGT controller, but with where the turbo currently sits i cant fit it in there, i need to move the turbo back a few inches. but i just want it on the road and running for now. its being tuned this fri for the time being. ill get a hydra and 1000cc injectors soon and get the vgt working and then retune.

i have a so-so build thread goin on mainelysubarus.com

http://www.mainelysubarus.com/forums...e351ve-bugeye/

for those that want to check it out. she'll be running 15lbs of boost for now, as more money fills my account over time ill start building a 2.71l motor or if i can a 2.9 and then swap that in at some point. ill also be upping the boost to 20lbs at some point and maybe more

from what I've seen from the compressor maps of those turbos, they're meant for pretty high pressure ratios (3 to 4) which is more around 40 psi

which if you think about it, it makes sense since the turbos are designed for diesel engines

or I'm incompetent and need to re-learn how to read a compressor map, which is just as probable

^ Your right, but at 20-22psi Im still on par with similar spec turbo's, relative to power. Just because the effeciency stays within a reasonable margin wayyy up high, doesnt mean at lower boost it wont make good power, it will, it just has a hell of a lot more head room than most. Up high is where they shine but this is not an experiment for a stock motor. Im lifting heads at 22-23psi with mine already. Got a motor coming together that should take care of things and let me see what these bitches can really do at 30+.

Ah, makes sense. I didn't realize you were on a stock block.

No,he's probably right. Probably off an isl"g" (g is for gas, as in natural gas, yes, a cummins with spark plugs) and any cummins turbo technology (formerly holset) vg turbocharger will have a water cooled chra. There are also some holset/ctt turbos with water cooled turbine housings used in marine apps.

This has been done and documented many times on dsm forums. i suggetst you check it out. Also been done on home mad turbo and there's alot of info on there. Basically just use an internal wastegate actuator hooked up to the sector shaft. Still needs an external wastegate to vent exhaust pressure though.

One thing most people don't realize about these vg turbos from holset/ctt is that, THEY AREN'T DESIGNED TO REDUCE BOOST THRESHOLD. They are designed to create backpressure, and it just so happens that they reduce boost threshold. I have seen only one instance of a cummins engine running a vg turbo WITHOUT egr. It was actually 2 days ago believe it or not, on an early ISL in a refuse truck.
VVT/VGT turbos are really not all that they are cracked up to be in a gasoline application. A VNT turbo (think 6.0 powerjoke and later duramax) on the other hand may be worth looking into, as you may actually be able to get the vanes to open up enough to control boost completely without a seperate wastegate.

I've had probably a hundred of the holset/cct turbos apart in ALL various sizes and states of wear. If any one of them would be close to being able to control boost and reduce threshold and do all of the things we would want it to do, and be easy to do it with, it would be the air actuated he431vg off of an early isc/isl. The compressor is slightly larger than the 351 (i believe, never taken measurements) and the hotside is a helluva lot larger than the 351's, making me believe you may be able to open the vanes wide enough to control boost. I honestly think that for the weight, the money and the fanagling required to get one of these vg turbos to work, you're probably time and money ahead using an even a brand new EFR turbo (remember, no ewg or bov required for most EFR's), and you'll get a turbo that will beat the snot out of it in the power department and be damn close in the spool department. plus, it'll weigh less than half of the vg turbo.

If you want to use a holset, imho, stick to the standard hx/hy35/40/52/55's and just skip right over the vg's. The normal ones are cheap as dirt (especially if you "know a guy"), spool and flow well already, and if you do some little tricks to them (think batmowheel) they will flow and spool like nobody's business. Plus, they aren't real picky about being balanced after they're modified. We r&r compressor wheels every now and then on some of the bigger stuff, and Cummins doesn't even MENTION balancing them. Not too many turbos out there you can rebuild for less than 80 bucks. They're 30+ year old technology, and priced accordingly.

Sorry for the rant, but i've been making cake pops for my sons 1st birthday for the last 4 hours, and i just needed alittle bit of car guy talk

No need for apologies. I have read through some of the DSM threads and seen them talk about using a wg actuator or a spring for VGT control, however no input from the Suby community so want an apples to apples comparison. Reason I asked was I found someone selling 2 351's at a decent price. I have also been eying some H1C's and HX35's for my winter project. Being that there are a small handful of Suby owners that are running Holsets just trying to get as much info as possible before choosing what platform to build from.

Thanks for the info and Happy Bday to ur son as well!

Do you mean he431ve? A google search for he431vg only shows this thread
If you do mean the ve, google searchs appear to say that the compressor wheel is the same as the 351, but has the VNT turbine instead. Now I know a lot of people worry about jamming on the vanes in the Garrett VNT turbos, which is why the Holset VGT is thought to be better since it's less likely to jam. Since you seem to have experience with these turbos, do you have any comments on this?
Also if the compressor wheel is the same as the 351, does that mean a batmowheel can be put on the he431ve as well?

No, no hx35 batmowheel yet, there was talk of one, but it's unlikely to happen soon I would guess. If the 431and 351 wheels are the same, then the batmowheel would be AWESOME. And I did mean 431vg not be. Ve means electrically controlled whereas the vg is controlled by an pneumatic actuator. The reason the vent turbos have problems is due to soot loading of egr'd diesels. Ctt vgt turbos suffer from the exact same issues and are no better as far as I'm concerned in the durability department.

Oh, and of anybody is wondering why there are nearly no electronic controls for the 351ve is due to cummins 1939can-bus control of the actuator (true of all of the ve turbos released since 2007). I believe fleece performance offers a controller, but they are $$$$ and all that does is further the cost and complexity of one of these projects. Furthermore, not sure if it will control the big turbos or not.

Side note, the 2010 and up 551's flow enough air for 600hp on a 15 liter diesel and have a smaller billet compressor wheel and housing (housing not billet, just so there is no confusion!!!!)compared to previous 551 variants. Problem is, they can, will and do self destruct right around 132k rpm sustained, so using the integrated shaft speed sensor would be a decent idea if u could figure a way to swing it.

Rotated the turbo. got rid of some piping. re-mockup. got another fuel pump and finally an AFPR...so attempting e85 soon. We shall see though.

How was it running before you changed things up?

BTW, you gotta get a different power steering line

Haha I do. It ran good before I changed it. I was running a smaller maf that was closer to the compressor so scaling at idle was a pita. Now I'm running a slightly bigger maf further away and the car wants to run a lot better. It peaks 20psi right around 4600rpm. Give or take a few 10ths. But I like it for what it is. I just wish they made a batmowheel for the hx35 :/

And you're on a 2.0/bc 280 motor, correct?
