Holset Turbos

[IPT]

I'm thinking more on the lines of puting a garret turbine wheel on a holset CHRA...

What size garret CHRA are you compairing? As big as I am going it may be closer...

If the garret TS turbine housing needs some TLC to get the holset CHRA to bolt up it will get it.

If you were to try and put a Garrett turbine wheel in a holset center section you will have to check the diameters of each shaft. Which as long as they are close you can get over or undersized bearing to make it fit. Then the other problem will be the length of the shaft itself. If it is not long enough the their will be nothing to tighten the compressor nut on and if it is too long then the piston ring and on other parts may not line up right. I think that the heat sheilds are rather simular. (need to look at one side by side) so that should not be too big of a problem.

Why do you want to use a Garrett turbine housing. If you need one that has a T3 or T4 inlet Bullseye has one that will do that.

Also why do you want to use a Garrett turbine wheel?? The holset wheels are a VERY good design. The only thing that I can think of would be to use one of garretts new GT line, but those things are not cheap wheels compared to the holsets.

I hope this helps.

For a bigger turbine housing A/R an wheel...

I suppose I could just use a holset turbine wheel but I'll have to check compatability and any neccessary machining with the housing.

I have talked to a guy in Alabama that has put down over 600 whp on the bullseyepower turbine housing, but if you want a bigger a/r then you should be able to get a holset CHRA to bolt up to the garrett turbine housing. You will just have to have the wheel profile cut into the it.

1029TSG, any news on the HY-35?

Has anyone gotten anywhere on determining which parts numbers are for which H1E? and if a particular one will work with the HX-40 kit?

 

[1029TSG]

The HY is s a work in progress, we have quite a few projects on the table. I think we decided after measuring that the H1E wont fit either housing.

 

[defrag010]

^ I think what dynatos was asking is if anyone has measured any of the different H1E numbers besides maglin's. Since the H1E has Alot of different part numbers and different turbine shafts, someone needs to find the H1E part number that will work in either of your housings...

I knew maglin's turbo wouldn't fit an HX40 housing because the guy at thompson diesel told me that number wouldn't bolt into a regular HX40 turbine housing. I've been trying to call around with a list of H1E part numbers to see if they will "fit" in the regular HX40 housing, but no one answers my calls.

I see some of you guys have to modify your water pipes. Do you have a spacer between the head and Manifold?

I have a 1" spacer on mine so I can use a tdo6 17c with out clearance probs. Does this mean I can use a Holset without a waterpipe clearance problem?
The only thing I can see is I might have a Rad clearance problem.

I have a hx35w and a hx40w (old dodge scrap turbos) apart if anyone needs a measurement (have a nice digital dial indicator in/mm).The only thing I cant mic. up is the cold side wheel off of the 35 (it's fubar).
I am in need of a donor 35 turbine wheel/shaft for a hybird project if anyone has an extra to sell.
I can tell you the shaft from the 40 and the 35 are identical.

Impossible....

 

[j.d.roost]

Impossible....
Have you had one of these apart ???
Bear with me while I take the pictures/upload them ect...
By shaft I am mean "shaft". Obviously the turbine wheel is bigger.......

hx35 on the right hx40 on the left.
I have pictures with the mic. on them if you need more proof.

 

[pinknuggit]

Ahh ok.... misunderstanding... I thought you meant shaft as a whole shaft assembly (which includes the turbine wheel).

yea, the shafts will be the same, only different wheel diameters...

actually,since you mentioned it... I'm interested to see what your measurements of the exducer and inducer of the HX40 turbine wheel are... especially how they compare with maglin's measurement of the H1E turbine.

I have been trying to do some research into the holset exhaust housings, i have a HX35W and was just trying to work out the A/R size of the exh' housing? i have E-mailed David@bullseye to see whether they have a conversion for the 12cm^2 to A/r.
I have a garret .70a/r , .84 and a 1.3 just to do some comparisons with to me it looks around the .84.
Any better guesses out there??

 

[pianoman]

IF you looking for what the A/R of daves housings are, that is propritary(sp?) information. All he says is inbetween .48 and .63.

 

[1029TSG]

That is correct.

 

[damnslowtsi]

Can you shed more light on the size of your exhaust housings by comparing them to PTE stuff? I 've got one not too long ago with supposedly .63 but the thing is quite small A buddy of mine has a full garrett in .63 and he says its day and night. Which one is bigger yours or pte (in case if you saw them side by side). Thanks.

 

[1029TSG]

I've only seen pictures of a PTE housing, so it would be hard to tell. We've had customers make 549 whp with our housing using a Holset cartridge and 651 whp on a T-66 with NOS. Our housing should be big enough to accomodate any street/strip application.

Hey guys, in case you wanted to know what one of these bad boys looked like installed, I mocked up an HX35. The HX40 will keep the same footprint as it uses the same diameter compressor cover. I will be using the hybrid Holset, and she will be ready to run very soon. Stay tuned for track numbers.

 

[PSI TSI]

Wow that looks awsome. What kind of Header is that?

Can someone anwser my questions I think they could be usefull for people to know.

I see some of you guys have to modify your water pipes. Do you have a spacer between the head and Manifold?

I have a 1" spacer on mine so I can use a tdo6 17c with out clearance probs. Does this mean I can use a Holset without a waterpipe clearance problem?
The only thing I can see is I might have a Rad clearance problem.

 

[joeracer321]

I have no spacer on my car at all. It took minor clearancing to get it to fit. Maybe two taps of the hammer. I would say less than 1/8" to get it to fit. If you have a 1" space you should have no problems getting it to fit.

 

[pianoman]

Look close at the first pic, you can see that its farily close to the water pipe, but like joeracer said, you can see its only a few taps and its cleared.

 

[pianoman]

Joeracer,

Can you list your mods on fuel system, fuel control, what type of gas, intercooler setup, motor setup, and spool times? Is that a ceramic coated DNP header?

 

[joeracer321]

I have one of everything. Check out my profile just about everything should be in there.

 

[joeracer321]

The data will be available as soon as I have it. I am still breaking in my motor, so it will be a little while.

 

[defrag010]

so how does it run so far? when do you start to see spool on the street?

 

[TimG]

The turbo almost clears the water pipe. Great. But you are using a custom header. Will it fit with the stock manifold? Thats is what I want to see.
