Hopefully the added displacement and the better rod ratio will allow me to spool this monster faster and rev higher to give me a nice powerband.

The next item I plan on purchasing is a manifold, but I am not sure what would work best. I am thinking about the shearer top mount, but I am worried about fit and clearance with my 2g. Do any of you hx52 guys have any info on that?

Thanks,
Justin

You too!! I order the same except i went with 9:5:1. Going to send the pistons out for some coating.

I want to see some pump gas numbers on these HX40 setups. Especially with SMIM's and cams. ( JMF DRAG SMIM Anyone )

Also and perhaps someone with some pics of how much they ported on their PR o2 housings?

Also does any of you Holset guys run a CAI? That could also help make that spool faster, it did for me on a e316g, along with doubling up springs in my external gate for as much spring pressure as possible. ( Minimum boost became 20psi though.)

[ezz-e]

Hey dsm-monster Is there a possibility that the hx40 pro wheel can be put into the H1E turbo housing?

Also if there is any one out there that has a 18mm housing around for a hx40 please PM me im looking for one desperately.

[dsm-onster]

I don't know for sure. See here. If you can swap to a 60mm compressor with the h1c/wh1c, then it's likely you can do the same with the h1e. The saft diameter of my h1c and wh1e are the same.

Who has a 50trim size turbo and doesn't have a cold air intake?

I did a direct swap from my small 16g to my bolton h1c (hx35 turbine wheel, 2mm smaller compressor inducer, same diameter exducer) in the holset results thread. Same spool speed, but logging 2lb/min more flow at 2psi lower peak boost and about 15* warmer intake temps. Same stretch of road. Same gear. Same cold air intake. Only difference was a 3" to 4" adapter instead of a 3" to 2 1/4" adapter.

My external gate spring is weaker than the stock 16g actuator. 5psi running off wastegate vs. 10psi with the small 16g. I didn't change the spring. I just used a boost controller. With the MBC turned *all the way* in, it would hold about 20psi. So no stronger spring trick to get faster spool.

[need2boostpsi]

so if your wanting to use the holset Hx35's 12^cm housing, is that a T3?

[dsm-onster]

Yes.

[need2boostpsi]

so the stock 12^cm housing and a T3 manifold would provide better top end power over the mitsu flange header and the small BEP housing? what about the large BEP housing?

[TSi_with_psi]

I'm about to put a 6 blade HX-40 on my car with the .55 bep housing. I have 3 questions.
1. Will the stock exhaust manifold work with the bep housing or will i need a spacer?
2. How do you recommend connecting to the compressor housing outlet? If you know the correct V-band size that would be great.
3. What is the thread count and size of the adapter i will need to attach my oil feed line to the turbo?

thanks guys.

Well, I got the hx35 8 blade on, was really cake. But I am very sad to say my spool sucks. 18-20 psi by 5k and nothing until then. It really sucks. I think the welder didn't make the arm long enough to keep pressure on the internal flapper but i fixed it. I will throw a log up via dsmlink and see what I can come up with. There are no boost leaks and the 4 layer exhaust gasket is on good. and all my turbo bolts are nice and tight with the stainless steel gasket.

[ezz-e]

Does any one no a good place to send the holset turbos to get rebuilt for some reason mines began to leak oil threw the exhaust housing last night while i was tuning it. not really sure why but it mostly happen when i was past 4k rpm.

DSMmonster it seems they use the 6 blade pro wheel im going to give them i call and see what they say on monday. if so i most likely will be going this rout with my H1E setup on my 2g. I once saw a H1e on ebay which was listed as a H1E compressor housing with a H1C turbine wheel in a 18cm housing. was supposedly rated to spool under 4k rpm and make 700+ Hp.

[Spidey]

95burgandyesi - something definitely isn't right, *especially* if you're using a bolt-on turbine housing.

ezz-e - any diesel performance shops should be able to rebuild for you, htturbo.com, citydiesel.net, I'm lucky to have a local Holset specialist shop I guess, tepturbos.com - you may give them a call as well, their prices are good. Where are you pulling oil from for the turbo? Running a restrictor? I know at least 2 locals who pulled oil from the filter housing and had smoking problems, too much pressure I think. I pulled mine from the head with no restrictor(no balance shafts on my 6-bolt either) and didn't have any smoking til the turbo blew from a giant boost leak.

Send him a PM. He rebuilds them for a living.

That's sad to hear. What turbine housing are you using?

Not really for a living; at least not yet, anyway.

It does fund my car build(s), however.

[danyz250f]

So i bought a hx35. Everybody is out of bep housings. So I have a few questions. If i make a manifold thats divided for the stock 12cm^2 housing would it spool as fast as the bep one. Also I have a mitsu flanged housing that i could just put a t3 flange on. Slower spool but the mani is made and would be super easy to retro fit.

Pretty much just wondering if anyone has put a divided manifold on the stock t3 housing and what kind of spool they would see.

The bep housing is $250+ so if i made a manifold it would be super cheap and make more peak hp. Just wondering if all the time fabricating would be worth it. Not that this turbo would be that hard. I just put a holset vgt on my other car and that was WAY harder than this would be.

This is going on a fwd auto 91 laser BTW.

[dsm-onster]

TimG went 132mph with the hx35 turbine wheel with the stock t3 housing and a t-netics manifold. Your setup with an adapter will flow close to the same, maybe a little less. Still plenty of turbine flow in my opinion. Full song at about 4100rpms is not bad for a turbo that flows 52ishlb min. If you have the 7blade compressor, your turbine setup will be plenty for the 57lb/min that compressor can flow.

1. My HX40 went on no problems and no spacer
2. 2.5 v-band I would think a 2 1/4 would work better but not sure if you can get them in
that size?

Way too much oil pressure?

I built a t3 divided manifold for my H1E (I think its on page 3) i've had a few problems with my install not to mention my hood flying up on me. But anyway it spooled quick somewhere around 3.5k. I didn't log it because it was just a test drive around the block. I will hopefully have something by this weekend, my buddy wants to race me at thwe drageway next weekend so I need to get thrashing. I will post something soon.

[dsm-onster]

That was with an h1e or with the h1c? The h1e has an hx40 turbine wheel. I've never seen a t3 flanged h1e.

EDIT: I see in thread 3 that you have the 16cm^2 t3 turbine housing 3500rpms spool speed with an hx40 turbine wheel and a 16cm^2 turbine housing! Gotta love twinscroll tech. Each volute of your turbine housing is as large as a bolton volute

[gixrman]

I took a H1C 16cm T3 housing and had it machined to fit the H1E turbine wheel. The H1E came with a T4 21cm housing.

[AHALLA05]

Dsm-onster: Thanks for all the suggestions and the super fast reply! Unfortunately I dont have a top mount manifold. Its a bottom mount(?) undivided t3 shearer manifold. Im gonna have to stay away from any adapter flanges due to the super low turbo position. I already had to grind the mount for my 30r's return fitting...

What is the spool and top characteristics of a standard HX35 vs. 35/40 hybrid vs. HX40. Most likely I would opt for the bep .70 housing.

[airmail96]

Ok so I have a line on an H1C the assy number (assy3531456) came back as the big H1C when I read the holset part number thread. The only thing is it mentioned having the webbing but no groove. as far as i can tell this one has the webbing and a groove or am I just thinking to hard on this.

I am running off the head with a inline filter. Unfortunately my aftermarket sender doesnt work right now but the stock gauge sits dead middle are wot and cruise if that helps. At idel it sits between the bottom and 1/3 mark. I run valvoline vr1 20-50

Its pulling oil from the oil filter housing. I have no balance shafts. Im using a 2g oil filter housing restrictor. Im going to try to port the oil filter housing and getting a feed from the head and placing a n2o jet as a restrictor. i notice most of the oil poors out when i rev it up. Should i order a rebuild kit for the turbo i hear it is easy to rebuild a holset?

jusmx141 I have pm you before but have never gotten a reply from you, please pm me im looking to get this turbo rebuilt.

Spring is almost here and i want to start contributing some info to the holset community on how this H1C 21cm housing will spool on a stock 2.0 with a divided manifold.

[ezz-e]

Hey Dsmonster what do you think about this turbo on ebay?

I apologize- it could've easily been overlooked. I try not to let that happen, but I get anywhere from 6 to 15 new PM's per day....I try to respond to every one, but I'm only one man working basically two full-time jobs. Answering a constant barrage of tech questions and rebuild inquiries on here is full-time job #3, but in order for me to have full-time job #2, I must answer every question possible!

Jus PM when you have the chance i wana see what i can do with this h1c and the h1e i have

[dsm-onster]

Airmail, you can't see the actual groove cut through the webbing in that pic. Just the webbing. If it has a 54mm inducer diameter, it is the big h1c.

Ezz-e, that compressor inlet looks different from other hx40 inlets I'm used to seeing. Looks better, bellmouthed. If it's real, it's the 58mm piece. With a 16cm^2 or 14cm^2 t3 turbine housing. Good upgrade for your current setup as this turbo with the bolton housing has just trapped a 580whp speed with more left in the tune and setup.

[airmail96]

Ah ok thanks DSM they pulled the auction on ebay for it :-(.

[talonDSMerr]

Since the outlet flange on the BEP housing is so big in diameter, has anyone had problems finding a gasket to use? Or is modifying the gasket necessary.
