Holset Turbos, PART 8

[prostreetdsmx1]

hey guys, just a quick heads up. I finally have the Holset Bolt on DSM housings available again.

http://www.dsmtuners.com/forums/ven...holset-holset-back-popular.html#post152309219

I get PM's about them ALL of the time from people in this thread so i figured I'd update it.

Thanks

another huge disappointment, i do not wish to reveal the sellers name because i do tink he is a niceguy
but just to share how much damage it had

i did notice some oil on the turbine wheel , but just tought to myself, must be some lube or maybe cos it was claimed 0mile , bt maybe it was started on the motor before

opened the compressor cover n measured it, damn its a 56mm billet wheel instead of 60mm, with a broken heart i accepted it and shot a pm to the seller, jst to inform him

today.
disaster struct when i opened up the turbine housing , i spinned the wheel , i noticed the center nut is not staying in at center, my buddy from the turbo shop just said "u got screwed" , got frustrated , i opened it up and put it onto the machine, this is what it shows , just watch the gauge , the shaft is actually bent

so guys, whts the best solution ? is it easy to get a hx40 turbine wheel ?

dsmonster , jusmx , h1e and hx40 wheel is the same ? if not mistaken the bent one on my hands is the 64mm/76mm wheel , i do have a hx35 58mm/70mm should i shove tht in or its the better to go for a bigger wheel ? , my dream is to maximize this turbo n paste it up on the dyno thread, dammmmm

 

[JusMX141]

h1e and hx40 wheel is the same ?

H1E turbine is the same, correct.

I agree, I wouldn't recommend running that turbo with such a turbine on it. A runout of less than .001" is acceptable; .005" will give far too much vibration and cause damage- the turbo may never be able to reach full spool.

If I'm not mistaken, your HX40 appears to have the 56mm compressor. If that's the case, I'd just put the HX35 turbine wheel and housing on it and you'd have a setup that nobody else has ever tried that I know of.

justin, do u happen to have a hx40 turbine n shaft laying around
or do u know where i could get one, i did contact goldfarb , jst waiting for their price on it. I probably will machine a t3 .82 garrett turbine housing onto this , so i guess it would still build top end. The seller found this link for me n he is willing to split the cost

bt it doesnt look like a genuine wheel , is it ok to go for it ?

[nfernotalon]

I just got my hx40 in the mail from goldfarb I was excited til I saw it came with a t4 housing! This thing is huge. Is there such a thing? I thought they all came in t3?

I do not have either for you, unfortunately. I don't stock many individual parts for Holsets because the turbos themselves can be had reasonably cheap, and the last time I priced a new Genuine turbine assembly for a HX40 it was either near or just over $300. For not much more you could buy a good used HX40.

i did contact goldfarb , jst waiting for their price on it. I probably will machine a t3 .82 garrett turbine housing onto this , so i guess it would still build top end.

If you're doing that, go for the HX35 turbine...as long as it's bigger than whatever turbine was used in the .82 Garrett housing. The added flow of the larger Garrett housing will more than make up for the difference of the smaller turbine. I've already seen the tiny T31 (Stage 3) Garrett turbines flow near 60 lb//min in a .82 T3 housing, so it should flow every bit of air the HX40 compressor can throw at it.

I'd take that turbo (56mm HX40) and install a HX35 turbine which I believe is 70mm inducer, 60mm exducer, and machine the .82 T3 Garrett housing to fit it. You'll end up with a damn quick-spooling HX40 that can flow every bit of the 62 lb/min the compressor is rated for.

Do not buy SHIT from that company.

Recently I was in need of a kit for a S366; I was quoted $150 for a Genuine BW kit from my supplier. Well I wanted to save as much money as possible since the thrust hardware in this particular turbo was fine...I really only needed journal bearings and seals.

I picked up a BAE kit for a shade under $100. When I got the kit, the journal bearings were WAY too big. I contacted BAE and they claimed that kit was only for S300's and would not fit a S366, which is bullshit because all of the S3xx turbos use the same turbine....the S366 is just a S300 with a 66mm compressor inducer, it has nothing to do with the journal bearings.

I send them the specs of the bearings I need, my message is ignored. Time is passing, I NEED MY PARTS, so I get them from Bullseye Power where I should have went in the first place. It was cheaper, and they were at my door in 2 days.

I tell BAE that I want to return the kit for a refund, and they reply to do so. I shipped the kit back, two weeks went past without a word or a refund from them. I have confirmation that my kit was delivered and signed for by Helen in the office, but no refund.

Took a Paypal claim to get my money back from those assholes.

 

[-red97rum-]

I rebuilt my HX35 with one of BAE's kits, it all fit right and has been holding up good so far. It's only been a few weeks but the turbo has seen 30psi pretty much the whole time. Checked shaft play the other day and it still feels the same as the day I put it on the car.

I ended up getting a new turbine wheel/shaft from a local shop so I can't speak for BAE's turbine shaft. Seems like their customer service is pretty shitty so I'm definitely going to look somewhere else next time I need turbo parts.

BAE is somewhat local to me Justin, so let me know if I need to drop their window with a friendly brick.

Just kidding! Of course I would never really do something like that

 

[thilaksharma]

Justin , thanks for the reply, i will source for a genuine used hx40 shaft or h1e , if i am unable to get one, then i will shove the h1c/hx35 wheel in.

Thanks a million.

 

[thilaksharma]

justin , have u had experience with Melett turbo parts ?

almost done with the twinscroll setup. hx40 6blade in a 16cm^2 housing. Custom manifold, dump tubes, and downpipe.

I will measure and adjust oil pressure at inlet on first startup. I will drill the restricter to .075 to start and go up from there if need be. My oil drain is identical to Calan's 3/4 ID hose, that I made a custom flange for.

I know I have 2 different gates, I already had the tial and had to go el'cheepo on the 2cnd one, but the tial spring works with it, so we will see how it goes.

I will have to post some logs on spool/etc. This is on a 2.0 running e85 etc.

I really don't want to get to far ahead of myself as far as results, but I will wait and see.

 

[Strm Trpr]

^^^ Nice work on the manifold, and on a 2g even?
What did you do about the upper radiator hose being so close to the #4 runner?
Are the 16cm^2 HX40 hotsides T3 or T4 inlet flange?

 

[abaum565]

sorry, divided T3 housing

 

[Strm Trpr]

Who made your manifold?

 

[abaum565]

Who made your manifold?

I did, along with the dump tubes, downpipe and intake extension.

For now I will put some wrap on the upper rad hose and then some heat sleave. But I will be switching to a 1g rad. I will just keep a close eye on it.

 

[Strm Trpr]

excellent work!

I need a divided T3 exhaust manifold with provisions for twin gates for my twin scroll HX35.

What materials did you use?
Did you back purge your welds?

PM me if you'd be willing to replicate one for my 2g T.S. HX35 set-up.
If not, I understand...

 

[black_gst]

what do you guys think? its in a .48A/R housing now, but if it turns out to choke the turbo ill switch it out for a .63A/R

Yikes- the .48 is going to yeild less flow than a .55 BEP housing....probably spool like crazy, but I'd imagine you're going to see peak airflow around 46-48lb/min.

 

[black_gst]

yeah he had that housing in stock so he went with it... i havent paid a dime for it yet so im not worried, how do you think a .63 will do? will i be able to ge the full potential of the hx35?

 

[LD25Delta9]

I'm going to try not to sound like a complete newb. I've read through most of the other parts of the holset threads, so I think I "kind-of" know what I'm talking about, but bare with me; I'm just getting into the technical aspects of turbos and Holset seems to be the big bad mammy jammy.

I'm looking into a genuine B-type H1e at a steal. Right around $200 with zero in and out, minimal up and down. I'm wondering if I should stay with the divided t4 or go to a BEP t3 Housing. I looked at the compressor maps of the h1e and it looked great. I'm just not sure what the HP/spool/TQ trade off would be for the BEP T3 housing. Any kind of help on these numbers would be great. Thanks.

Awesome job!! I like how nicely everything is routed.

Looking forward to seeing results

Yeah he did an awesome job on his set-up.
Any results from your set-up?

 

[Mr Peepers]

Posted a while back on this thread. 11.2@129 street tire shakedown pass at the shootout at 25 psi. ~3050 with me in it. Hits 25 psi before 3500 in 3rd and just after 3k in 5th Need to throw a new 3-4 hub and slider in before I can do anything else at this psi, and new injectors before I can turn up the wick.

Yep, I saw that, Congrats.
Are you still running the HK$ 264/272's?

Any better pictures of the exhaust? That's not a 90 degree bend on the DP is it?

 

[abaum565]

Here is a pic of the downpipe before I coated it. Right off the turbo it's a 180* bend that is cut at an angle, then delicately molded to fit the vband. I then added some support with a plate I moulded aroudn the dp under the vband. It's all 3" mild steel. I don't have a bender (obviously) so everything was pie cut and welded. All materials are from Columbia River Mandrel Bending
