Hey jus.. is it possible for me to modify my hx52 with an available bigger wheel say maybe the 52pro or even something bigger? I wanna avoid going back to my BW475.

I'm honestly not sure....I don't know what the shaft specs are between the 50, 52, and 55 so I can't tell you if the wheels are interchangeable. Obviously you can't use a wheel with too large of a shaft bore- that's what holds us back from building a HX40 with a super-huge monster-airflow compressor like the FP HTA3794 and making the HX40 into a 900hp-capable T3-frame turbo.

Going back? How far did you get with either turbo ? Don't kick my a$$. I really want to know why you would change turbos with the potential of either? I recall you bellyaching about guying saying they are trying various holset turbos, then bailing. You where very upset they were doing that

My situation was different. I actually had the s400 series to begin with. When everyone basically belly flopped on the HX52s I picked up a turbo that was sold to me as a 52Pro and it turned out to simply be a HX52 billet.

So all in all the plans were to switch over and run the 52Pro which wouldn't be as much of a sacrifice but now its all up in the air hence me wondering what other possible options I might have. A Hybrid 52 or the ability to upgrade to the pro52 wheel would be such an opportunity...

I wanna definitely see what the big Holsets can do but not at the sacrifice of my end goals for my build. If they can't perform on the setup I put together then they simply cant perform .

Even so is it a possibility to source a 52pro center section and simply put it in the regular HX52 housings?

well this winter i been thinking about the potental of this hy35 sitting here at my shop and currently a have the hx35 bolted on.... it runs great and has amazing top end but the bottom end sucks due to the factort 14cm/2 housing.... so instead of getting the bulls eye housing i wanted to test this hy35 out because not a lot of ppl are useing them..... chim in on thoughts and ideas...

THIS IS A ROUGH MOCK UP..... if i go through with it ill most like have a few extra parts to get... im still makin the list now...

You have a HE351, not a HY35.

So I got my dynojet run file from my 14b setup(blue) and laid it over my hx35 run file(red) I found it very interesting.



Same exact setup except for going from a 14b w/ 7cm^2 turbine housing to a twin scroll hx35 and larger injectors. Notice how the power and torque curves almost mirror each other. The hx35 is already producing more torque than the 14b before 3500rpm

EDIT: Correction, the 14b was still on a SMIC and SAFC at that time. Still shouldn't really affect spool.

I found my dyno and logs from both my bolt-on HX35 and E316G car and your setup which is pretty close to my old car with the HX35 would outspool me by 400-500rpm, I wouldn't see full boost until 42-4300rpms.
The 16G on the dyno looks to be about 100-200rpms slower.

Could one make a shaft sleeve to adapt the larger bore to the smaller shaft?

How much slower of spool could you expect with the .70 t3 housing on an hx-35 with 272/272 cams and 8.3 CR compared to the same engine but the .55 bolton housing on the hx-35? I saw the deal at S&R and it kind of sparked some thoughts.

It's possible, sure- but I'm sure it would be costly; not to mention you'd still be stuck with the issue of not having a compressor cover. You can't machine a HX40 cover too much larger without cutting into the MWE webbing....the same reason you can't machine a 54mm 7-blade HX35 compressor cover to fit a 60mm HX40 wheel.

Ohh, the comp cover is a much better reason than a mismatched shaft. I can make the adapter, but not the comp housing.

Would this work as a restrictor on an hx35?

Most Holset oil inlets are not threaded for such a flange, so I'm going to say no.

TURBO OIL RESTRICTOR AN-4 BILLET ALUMINUM - eBay (item 260591740295 end time Jan-19-11 13:22:36 PST)

What about this one? I saw another member use it right off of the ofh. Is that good?

You can use it as long as you're using a -4AN feed line, but .075" is a bit small depending on your incoming oil pressure. I wouldn't recommend a .075" restrictor unless your oil pressure at the turbo is well over 100psi and you're only using a -10AN drain.

here is my buddy return. its a modded stock return from a cummins, which is 7/8id to a 1 inch barb.

Whats the mod? The bend?
Can we get this from the dealer?

Just make sure it clears the front engine mount might have to trim that engine mount depending on turbo placement and manifold.

30psi by 3800rpm on a stock Evo with a 1.15 A/R TS T4 housing ~59lbs/min And another great thing is, if I ever decide to float the scratch for a larger EFR turbo in the future, it would bolt right in.

i havent posted on this site in years, but seeing that youre running this turbo got me excited. That really is an excellent turbo, and was the precursor to the EFR 7670 - in fact the two turbine wheels share identical geometry.. Im not sure if my EFR will be ready by the time my car needs it, so if not thats the turbo i'll be running

I bought that exact turbo, had the 3" v-band mod done to it and even had the shop gasket match the T4 inlet.
It was sitting on my pool table for a weekend staring at me.
The following Monday I emailed the shop I bought it from and asked if I could send it back.
I thought it was a long shot, but they offered to take it back.
So I did, and only lost $20 from original shipping and $28 to have it shipped back.
Pfffttt, that's one tank of 87 octane for my commuter...

I'll soon be the proud owner of an EFR7670 in the 1.05 A/R TS T4 housing.

Hey, you're Geoff, the owner of Full-Race.
I bought that set-up from Raffi.
You guys took care of me.
I did have to buy a T4 blanket, but now I can use it on my new EFR7670.
Any word as to when EFR's will be shipping out?

The EFR 8374 will be my next turbo!! titanium-aluminide turbine wheels!!! Im so in.. Their suppose to be comming out with more than the 3 optional turbine housings they offer now later in the year so Im going to wait for that. I will be doing a t4 topmount is the plan. But for now my Holset works just fine. I will be selling my HX40/35, tial bov, tial wastgate, and T3 manifold to help fund this project when Im ready. For those of you who havent read or know what we are talking about here you go...

Anyone have pics of a -12AN drain line installed with a HX35 or HX40, I'm thinking clearance may be an issue but i like this idea from above:

I had a new member from central america, Omikron, conact me with regards to some smaller variations. I think he's looking for a compareable OEM size turbo. Specific, he's got a HX27 and was looking at a HE221. Has anyone here come across any details regarding those?

Id like to find a HE221w. The only one ive seen was on ebay about a year ago. I ran the bid way up on it before giving up though. Whoever won it really wanted it. It is used on the ISBe 4.5L 4 cylinder Cummins. I used to have more info on it, but ive switched computers since then. IIRC, i use to have a link to a 2.0L gas engine making 400+whp in europe that was using one, but i cant find it anymore. I have a few opinions about it, but no personal experience with it.

Here was the tag info.
Model # HE221W
Assy # 4044884
Serial # D0805153052
Cust # 4044887


Here is the email i got back from Cummins about it.

Cummins said:

The inducer/exducer diameters of the comp stage are 44.2 and 60 respectively.
For the turb stage, they are 52 and 46.6 respectively.
The turbine housing critical area is 6 sq.cm.

I'm afraid I can't provide the flow details you require, my apologies.

The impeller is MFS.

I hope that helps.
Regards,
John.

Im not sure exactly what you were looking for, but hopefully that helps a little.

here u go, two of my holsets
should go into the cars very soon

For building the turbo for me

Haha, without Dsmonster and jusmx , i wouldnt be owning any one of these, good info n support all the way dudes

Hey guys, this is a pic of my 7 blade HX-35 with its stock 12cm^2 housing versus my twin scroll t3 mani from redjack racing. Obviously you can tell the difference between the outlet/inlet of the turbo and mani. The turbo's inlet is very rounded on the edge versus the much squarer outlet of the mani. I am assuming I'll need to port the inlet of the turbo to match the flange on the mani? That is my plan, just wanted to run that by you guys. I haven't read anything on having to port the t3 inlet on the turbo so I thought I would share that.
