Holset Turbos, PART 5

[aero_sallee]

I rigged-up a stock 14b actuator on the bolt-on housing and it worked fine for me until I was trying to boost past 22+psi. I don't think it was meant for 22+psi from an H1E compared to 22psi on a 14b . If you'd like, I can find some pictures and post them up.

I did the exact same thing. Never got to try raising the boost though.

Here are some pics. I think they were posted way back in one of the first threads.

Nice setup with the wastegate! I coudn't figure out how to get mine that way, so I mounted mine towards the power steering pump. It came off of the p/s pump and It worked alright, not ideal though.

 

[dsm-onster]

MHI actuators have weak springs. A used Garrett actuator would have held on for a little more boost before blowing open the huge internal gate flapper on the BEP bolton housing. There are a few of ways to cure the blowing open of the flapper. One is a stronger spring in the actuator. Another is more spring preload: shim the actuator either inside or shim the whole assembly out from the mounting bracket. Another is to extend the flapper arm length. This gives the actuator more leverage against the flapper, but you will loose a little flapper throw. I never had a problem with the loss of the flapper throw, but it did really help men with the internally gated 60-1 I had with the bolton housing.

Has anyone pieced together there own oil line kit? I mean come on $120+ thats one hell of a mark up.

 

[dsm-onster]

I bought a stock cummins truck braided steel oil feed line from ebay. I took it to lowes and hunted through the small fittings/adapters/pipe section until I found what worked. I cannot remember what I used. I saved the packages but my wife threw them away "purging" my desk.

I'd run the the local plumbers store and see what you can do. The stock oil feed line froma cummins pickup is too short to feed off the OFH by itself. I used some copper line. I recommend some braided line you can pick up many places, use an adapter or series of adapters to feed from the additional braided line into the stock cummins truck line and another adapter or series of adapters to feed out of the ofh into the additional braided line.

All I'm saying is that it is definately possible. Is it worth saving about $50-60? I don't know.

 

[b00stedtalon2]

My HX52 setup is running pretty good, took it for its first spin today. I am on stock injectors and on a stock base map until spring. I saw about 5psi at around 4.3k until I let off. It felt like a fast 14b car

Biglady's friend saw full boost by 6.5K. . . with the non-divided manifold. Good stuff. D@mn good spool speed for a twinscroll turbo the size of a gt42.

I still can't believe you're going to use the stock intake manifold . It will be interesting to see your results. Keep us updated!

Thanks bro. Yeah it spools up pretty quick. I'll be getting a jmf manifold sometime in the future but for now stock it is! Should be pretty interesting. BTW, the car sounds f*cking awesome with the 4" side exit.

 

[Slippi84]

Where's the video man . Looks good. Where are you corner lights? Man you are all about weight reduction first it was one wastegate now it's no corner lights o j/k

I too look forward to how the 4" side exit exhaust will sound. 5psi by 4.3k isn't bad. It's hard to get an idea of what that means because your just kinda running a base setup for now but def looking forward to seeing what you do once you get everything working right.

DAYUM!!! i never realized how much an HX82 turbo can flow!

A moderator on This Diesel Forum Turbo Flow Rates - Page 3 - Competition Diesel.Com - Bringing The BEST Together

from what i read the HX50 has a larger wheel than the HX52, it shares the same size compressor wheel as the HX55.

 

[dsm-onster]

The hx52 flows 90ish lb/min.

 

[turbotalon1g]

I am too running into the cost factor of running a holset.

I want to keep internal housing as my dsm is about to become my year round car.
I want HX35 in bolt on housing internal gate, but everytime like the other guy the price is almost $500 from turbo trader, any help anyone? Am i looking at something wrong?
Because then you add the price of the holset and I am at $700+

 

[420a-t]

you could to external for pretty cheap. People have used ebay wastegates and used the stock manifold to mount it on. That's less than $100 right there to have an external wastegate setup. Then you factor in turbo cost, new housing cost (if you want) and oil lines. IMO, I'm glad I went external now. On this big of a turbo, it's a wise choice. Do it once, do it right (which I didn't do and went internal for a little bit. Now i"m done playing around and went external, ).

WTF I'm lost here your adding up two turbo's it sounds like. The housing from turbo trader isn't 500 the WHOLE turbo is 500 then your adding I guess another 200 for a turbo which doesn't make sense. Anyway what makes you think you can't run a external year round. External wastegates are more effective and in a bolt on housing cheaper than going internal too. Pick up a bolt on housing for like 200-250max a hx35 wherever you can get it the cheapest shouldn't be over 300 so that's 550 max then pick up a o2 housing that has a built in external 38mm flange like punishment racing or even they have them on ebay for cheap and then of course a 38mm external and you can bolt it up to your exsisting exhaust and be set. You should not spend 700 just for a turbo your hole turbo setup should be about 700. You find another brand of turbo other than a 16g internal gated that will cost you less than this which by the way the hx35 will outperform a 16g in every way possible in bolt on form.

Yeah even though I think that 1000whp is possible if you max out a hx52 I don't think it's rated over 101lbs/min where did you get those numbers from?

 

[gixrman]

I just got done ceramic coating my jhr manifold and the hotside of my hx52 last night came out real good. I did 2 coats on friday waited a couple days then did the last coat as per the can. I used VHT flamable cermaic coating which is rated to like 1300-2000* in flat black.

I used the same stuff, its held up good.

Thanks for helping me out.
$329 for bolt-on housing kit from turbotrader, +150 for internal +80 for actuator ($560)
Turbo - $250
I would like to stay internal to keep room and engine bay temps down and simplicity. I run the car on E85 So I don't care for low boost, looking to hit 30psi and stay there.
I pretty much maxed the 16G out and I want something with more lag with about the same or higher power, I don't really care about the power part as long as its not slower.
Also I found a SBR G50 for $350 or best offer local to me, would that be a better deal?
Although I kinda want the holset because it sounds amazing and I would always wonder about it, also if i did get a holset, should I do 7-blade or 8-blade? would be in mitsu housing.

 

[dsm-onster]

You will have a hard time achieving HIGH boost with the internal gate. Not the other way around.

I am too running into the cost factor of running a holset.

To add, Hx35 $350, Bolton housing $220. Total $570 You can't get another 500whp turbo used for that price. Nore one that would spool as fast as the 16g for that price.

Everything else you're mentioning are what you have to buy for all other 500whp turbos. Now, we have developed a cheaper route that works. Ebay external gate $80 shipped, Ebay tubular o2 housing (now I wish I had gone for the o2 housing with the WG dump) $80 shipped. Weld on the flanges sold with the ebay external gate onto the o2 housing and down pipe $0-$100. Oil lines $100. $260-$360

You can run an internally gated hx35 for $600 plus the actuator. How cheap can you get for a bolton turbo? What were you expecting? To get a turbo with a gt30r-like compressor map that bolts on and spools faster, for the price of a used 16g?

You can't get a good bolton turbo that flows as much as the hx35 for the price of a new evo3 16g, even used. Maybe a used 50-trim or used 20g. So you can decide between a lower flowing slower spooling used 50-trim or used 20g or an hx35. Where can you get an fp3052 used for the price of an used hx35 with a bolton housing? Who would run such a turbo internally gated? Oil lines and water lines and a means to gate the exhaust flow still has to be addressed. Best thing about the the hx35 is that for under $200 you can have your old hx35 rebuilt to new. A used bb FP3052 will need an $800 core replacement to rebuild it to new.

Guys, if you have a 16g budget, then you can't expect to put down over 450whp. It takes alot of money to build a car worthy of a 500whp turbo. The holset is still by far the most affordable turbo for the goal, whether or not you can build your entire setup for the price of a 16g. . . Now, you can always keep your eyes open for the right h1c or h1e turbos. They have older compressor tech and usually go for less money.

The difference between that used g50 and a used holset with an internally gated bolton housing is about $150. Nevermind the reputation for a moment. You will be paying $150 for 500rpms faster spool speed and about 4lb/min more flow. Many guys pay $1500 plus assembly/machining to build a stroker setup that will shave off 500rpms spool speed and increase flow about 50hp for the same setup.

If the g50 comes with all the lines and the actuator, then someone is giving it away. Why?

 

[turbotalon1g]

^Thanks for the enlightening words.
My main concern for not going external is Room in the engine bay I hated it with the 61 i had. I will spend the money and get the car done right.
Its something I have believed in but I try to keep the car budget too, its basically $4200 one of the cleanest dsms in the state and runs 11.7s and is above 400hp and 450tq.
But plan is Ebay o2 housing, WG, HX35 7-blade and bolton cause i already have FP mani. and I would rather have a cast manifold for longevity purposes.
You should post your post from that other thread about the turbos and spool up, i think the thread made by Iroc G

 

[need2boostpsi]

Yeah even though I think that 1000whp is possible if you max out a hx52 I don't think it's rated over 101lbs/min where did you get those numbers from?

sorry forgot the link, its up there now!

 

[Slippi84]

Hmm I didn't realise that the hx50 was bigger that is news to me. I don't think I will have problems reaching my gaols with a hx52 but I did pass up a hx50 with billet wheel to get my hx52.

 

[Slippi84]

take this with a grain of salt, but i found it to be intresting

Model Compressor Turbine
Holset HX50 2.48 2.835
Holset HX50 2.638 3.031
Holset HX55 2.638 3.031
Holset HX55 2.835 3.031


There are two different hx50's it looks like. Probably same as the hx40 there is a super hx50 which has the hx55 wheel which is why the other numbers show the hx50 flowing more than the hx52.

 

[GST95]

I would like to stay internal to keep room and engine bay temps down and simplicity. I run the car on E85 So I don't care for low boost, looking to hit 30psi and stay there.

Here is another budget option. Holset gated housing Free(comes with turbo), Mitsu to t3 adapter plate >$50, make your own v-band o2 eliminator $70, Port the wastegate hole to 25mm free, turbo $250. Total $370. A little extra if you cant do it yourself, but you should be able to find somebody to do it at a reasonable price and still be cheap.

Why is 30psi your limit? Is there something that is your limiting factor, or is that just a number you picked? If you have big enough injectors, you will be able to run more boost then that without knock.

 

[dsm-onster]

That is an option. The hx35 with the stock 12cm^2 housing spools to +20psi by about 4K and 272s, based on TimG's results. This is a good option if you're ok with an adapterplate. I usually don't mention that because many get spooked by having 2 gaskets. And worry about the transition. But, really a 2g manifold outlet holeis not that much different from a t3 flange hole. The adapter plate plus the housing plus the manifold would be plenty of 'transition length' to blend in the differences to a smooth transition.

 

[dsmdizzle]

So I picked up my holset hx40 today. I bought it from a guy who works at a cummins repair shop and he said this thing was sitting in the shop collecting dust so he decided to sell it. It is brand new from cummins and has a build date on it of 08/14/08.

It has a 18cm2 turbine side on it but I going to go with the bep bolt on housing. I have a 2g piston 1g rod combo in the bottom end, 780's, 255, dsmlink, fmic, 3 inch, ss equal length mani, ect. I am currently running an evo3 at 20psi on pump. It runs really well but I am wanting more.

I will be buying and installing with the turbo, a jmf smim, 272's, cometic, arp's, meth, tial 38, 3 inch 02 housing.

Here are some numbers from the tag, maybe you guys may be able to tell me something.
Assy. 3597576
Serial. 3514352
