Holset Turbos, PART 4

[ihatedsms]

Turns out BEP dose not make a T4 housing.

My question is, what T4 holset housing would i want to run? What are my options. And will having an undivided T4 manifold with a holset divided housing be a problem? I do not want to run the holset internal, I want to go external on the manifold. So who has done this? Im sure there is someone.

Any help would be very much appreciated!
Thanks.

Which turbo you looking at man hx40? T4 divided holset housings are not that hard to find and will help A LOT with spool and power.

Yea HX40, and thats what im probably going to end up doing.

I have found a few, I almost won a bid on ebay the other day but it was an 8 blade.

Where do can you find the Holset HX40 T4 divided housing? I been looking a long time for those and what's the A/R size? I've seen a H1E housing but it's 22cm which is quite large.

Contact this guy he has a whole warehouse full of holsets. I picked up my t3 Hx35 from him for $35 (it was seized up).

Would i be able to have a T4 garret housing machined to except a hX40?

you shouldve never said that...his inbox is about to be FULL!

you just rebuilt that hx35 and you were all set?

 

[dsm-onster]

There are several volvo turbo bricks running around with holset hx35 and hx40 turbos with garrett .63 ar housings and .84 housings. It will definately work. You can even have an hx35 machined to fit an hx40 turbine wheel .

I saw the hx35 in the BEP housing make a smidge over 500 HP.

I'm kind of giving up hope on snagging a hx35...i may just do the WH1C...i just hope in the BEP housing it'll reach 450/500 hp.

The wh1c compressor has the same inducer and exducer diameters as the earlt 52lb/min hx35 wheels. It also has the same shape and angle blades and same number of blades. I dont' even know why there's a different part number between the wh1c and early hx35 is that according to many the hx wheel come from the factory balanced. . . So I think you should meet your goal with the wh1c just fine.

Yeah that's another option. If you go that route look for like a .84 t4 hotside or just under for good spool and power.

 

[ihatedsms]

Thats exactly what i want to run, T4 .84 ar. But i didnt know if i can do this (machine a garrect housing). Do you know this for a fact? Because if so im going to order the housing i need now.

I was gonna pick up one off a tuner on here and make it work and he measured and said it was a match and could be done but I have never retro fitted one myself so you might want to research more but as per him and maybe monster or someone has done it and can help I think it will work.

Nope I bought the HX35 for the smaller 16cm housing and machined it to fit my H1E turbine. The funny thing is there was a chunk of metal stuck in the turbine wheel of the HX35 and thats why it was seized.

I have been looking around, I belive one guy on these holset threads did it with a t3 housing. I will wait to see what other people say. Hopefully its doable. I have read that the hx35 and 40 wheels are to big for a garrett housing, so i know they can be machined bigger, the question is will it bolt up.

 

[dsm-onster]

I have a pic of the one of the volvo guy's hx40 in a .84 a/r t4 housing. . . If a larger q trim t4 turbine wheel can fit in a t4 housing then certainly an hx40 turbine wheel. The below pic is mis labeled as an hx40 commonly has a 19cm^2 housing not a 17cm^2 housing. . . I think there is a guy running a .84 a/r garrett housing on their hx40, too.

 

[dsm-onster]

I just can't find a place that will actually do this. Can a typical machine shop perform this cut? Can the wheel curvature from inducer to exducer be measured and duplicated on a metal cutting router? I know BEP, FP, and PTE can cut their turbine housings for all sorts of turbine wheels.

 

[420a-t]

I have a brand new divided h1e turbine housing if someone wants to try it on an hx-40 let me know. I'd be fine with shipping it to someone if they pay shipping and we figure out a price for it before I ship it

Can i use this kit for my holset hx35 with BEP housing? EXTREME PSI : Your #1 Source for In Stock Performance Parts - Oil Feedline Kit w/ 15 Micron Filter (Oil Filter Location): Mitsubishi Eclipse 90-99

if you scroll down on the "turbo fitting" drop down menu, there's an option to select Holset.

I hate to ask but what is the difference between the HX35 and a H1c? I screwed up and stated I had a HX35 when it is a H1C. Heres some pictures.

The thing I have noticed about the H1E vs HX30 turbine housings is, with the H1E the turbine wheel to housing tolerances are MUCH larger than with a Hx40.
The 26cm and 22cm H1e housings I have have a far larger gap than is found on the 19cm HX40 housing I have. The turbine wheel inducer and exducer's on the ones I've had measure the same between the 40 and 1E, but the depth is different. Wouldn't let the HX40 housing work on the H1e, the contoured part that transitions between the inducer and exducer curve is off and hits before the housing is fully on.

If all H1E's are like the 3 I've had, I would expect a slightly turned to fit HX40 housing would spool better on an H1E than the stock housing will.

The H1E would definitely be able to have more shaft play than the Hx40 before the turbine wheel hit though.

D@mn. You have a small h1c. You can tell because it does not have the MWE groove. And the compressor inducer measures 44mm. Which yours does. The big h1c has a 54mm inducer. The big h1c has a 2mm smaller inducer than the early 8blade hx35 and flows about 3-4lb/min than the early hx35. The early hx35 flows 52 lb/min. The 44mm small h1c likely flows between an evo3 16g and a small 16g.

It does have 7 blades so it MAY flow more than this. But we just don't have enough information to know. The 7blade hx35 flows 15% more than the same inducer 8blade hx35. It may flow closer to a big h1c than the diesel guys give them credit for. Maybe 46 lb/min which is about where an 18g is done. Good thing is that is should spool as fast or faster than a td05h 18g and definately faster than a td06sl 18g. We know the turbine out flows the td06sl 7cm^2 MHI turbine. So If the compressor can keep up with the 18g, this wiould be like a faster spooling 18g that is more pumpgas friendly. It would be good to know what this turbo can do. The turbine wheel is apparently the same as the big h1c.

Aero_salle, here the bullseye forum thread on the h1c/h1e fitment into the hx40/hx35 cut housings: Holset hx40/H1E. Apparently there are at least some that fit right in. These seam to be the WH1E turbos with the 19cm^2 turbine housing. Like the one I have. . . Apparently, more than one thought that the turbine wheel didn't fit because the wheel was "rubbing" before it was able to slide fully onto the chra, but when they used a hammer they found out that it does .

I know my big h1c fits right in to the hx35 cut housing, you need garrett clamps or modify some washers.

Sweet deal thats the info i was looking for. And hey on that link those housing are just for the hx35 right? It didnt say anything about the hx40, i can get one of those for a 35 housing and have that machined, or i can just go the Garrett route.

And im guessing they are all 4 inch vband and they dont say .ar's. or if there t3, t4.

I just can't find a place that will actually do this. Can a typical machine shop perform this cut? Can the wheel curvature from inducer to exducer be measured and duplicated on a metal cutting router? I know BEP, FP, and PTE can cut their turbine housings for all sorts of turbine wheels.

Im sure machine shops can do it, Its probably IF they would do it. They might not want to touch it. I know a guy that has a machine shop and builds v8 race motors so im sure he would help me out.

That doesn't suprise me at all. There are so many variants of these turbos with the same name. Next time I'm home I'll try and get a picture of the difference in turbine wheel tolerance on the H1E and Hx40 housings that I have.

 

[ihatedsms]

Well guys i bid on another holset, its a 6 blade hx35/40 hybrid less then 50 miles on it. If i dont win the bid im just going to get a T4 masterpower t-61.

Will see what happens!

 

[dsm-onster]

Well the 35/40 is a GREAT turbo. Look what Tim did with it in the stock housing, which I strongly recommend for such a turbo. But the t-61 is in another relm. So again what are your goals? The hx35 turbine is NOT big enough to flow what the hx40 6-blade can flow. Which is about what the t-61 can do. If you'r looking for 650ish whp then I definately understand why you chose the t-61 or the hx40, but don't get a hybrid. It will very difficult. I won't say 650whp isn't possible with the hx35 turbine, but highly unlikely. I think it's a great choice, but not for over 600whp.

Well right now im shooting for 500 whp. This is on a stock rebuilt 6-bolt, o-ringed head. (Keep in mind the car only weight 2500lbs) I have another block im going to be building for the car, but for right now the motor is going to be stock. Thats why i figuerd a hx35/hx40 hybrid would be nice for right now because on 30psi (the most im going to run on the stock motor) would get me where i want to be, Then i can keep the same turbo when i throw my built motor in and just run alot more boost and spray it!

So if i got with the hybrid im only looking for 500 to 550 on a stock bottom end which it should be capable of doing, then with the built motor im looking 600+ and spraying it.

Im looking for the same goals with the t-61. I have been back and forth for the last 4 months on deciding what turbo to go with, (hx40 or t61) I have been having a hard time finding the exact holset turbo i want, but the t-61 is a phone call away.

Tomarro will be judgement day. One of the turbos will be orderd, we will see which one it is.
