Questions for Justin...

Question for the master. What is the difference between the gtx35R and the GT35R

Justin,
Would I have to machine or get a different compressor housing if I were to switch out my 56mm 8 blade HX35 comp wheel with a 56mm 7 blade comp wheel? Thanks in advance!

One has a cast compressor, one has a billet compressor.

There are no 56mm 7-blade HX35 compressor wheels.

Thanks for your help!

Justin I am currently looking for oiling and draining lines for my newly acquired hx35. I have balance shafts in my car and I read in the holset thread that my oil pressure should be within holsets specs. Would you recommend me to just run a -4an line from the ofh to the turbo, run a -3an line or drill out my .030 Fp filter with a 1/16th or 5/64 drill bit?

I have a ton more questions regarding hx35 setup but im sure the are answered in the 12595290637 holset threads on this site (and my question has probably been answered also but everything related to tje holset is hard to find/know what the most updated info is)

 

[JusMX141]

Use whatever restrictor combination you need to get your oil pressure within spec at the turbo. I can't tell you what restrictor to use because I don't know what your oil pressure is.

Justin have you ever rebuilt a borg warner variable geometry turbo? I have one starring at me right now and I'm wanting to send it off to you.

This may have been covered, but I'm dead tired after working 11-7am last night and searching. Justin, can you rebuild a 14b that needs a turbine and compressor wheel? (or would it be possible to have the 14b turned into a td05h 16g hydrid?). I bought a blown up 14b for $20 locally and am just wondering what my options are. As you know, 16g's are upwards of a $1,000 now a days. I saw in your free lancer ad that you rebuild turbo's if the compressor and turbine wheels are fine, mine I don't think fit.

Nope, I tend to stay away from the VGT turbos for liability reasons as they're generally electronically-actuated, and that's something that is out of my control. If someone installs one of my rebuilds and the VGT doesn't work properly due to an electronic issue, they'll want me to cover it- and I'll have nothing to do with that bullshit.

For cost-effectiveness, you should have left the $20 pile of junk alone and bought a $50 14B core with no wheel damage from someone on here....then have that one rebuilt.

I've been looking for a good 14b rebuildable core, but the only things I find are $100 + shipping. Add a rebuild, and shipping to and from, and I end up with a $300 14b

 

[JusMX141]

Take a $20 14B with damage to both wheels, possibly damage to the sealing surface on the center housing as well....then throw that in the scrap pile because it can't be rebuilt, and you're right back at square one. See what I'm saying here.

Even if your center housing is still good- a rebuild plus a new turbine, compressor, and rebalance is going to exceed $300 by a good bit.

 

[e85_4g63]

Darn.. well it that case, you have a PM.

 

[HaveBlue83]

ok, thx for answering my turbo storage position question.

this thread is AWESOME .

heres another...should a journal bearing turbo sitting on a shelf be filled up with some fresh oil and spun a lil bit to keep everything fresh before capping off the feed/drain holes? I don't want this thing getting hurt when its ready to go and currently dry that I can see.

 

[JusMX141]

I don't see the necessity to keep the cartridge full. As long as the journals have some oil in them you should be fine.

Besides, a full cartridge will eventually drain itself anyway because the seals don't actually seal 100% by design.

 

[jmelocik]

Ok so with the minor inspection I did and found that the VGT guide vanes are already trashed, I have another turbo here. Borg Warner RE508973, I know what it came off of but would like to know it's potential application. It's a t-3 twin scroll so who knows, it may have some decent potential.

Hello, I have a blown PTE DBB 5031rle and i wanted to use the turbine wheel for another application as it's in excellent condition. But as I measured the that where the bearings go, where the turbine side bearing rides, it fits fine. Now where the compressor side bearing would ride, the diameter of the shaft is smaller. So in other words the turbine shaft itself has 2 different OD areas where both bearings ride in. Could it be converted/milled to fit another type of bearing?

 

[JusMX141]

Probably not- they've already taken a standard T3 shaft and machined it to work with ball bearings....I can't think of any bearings with the same O.D. as the T3 bearings but a smaller I.D. to work with a smaller-machined shaft. Not only that you're taking away from the structural integrity of the shaft- it's only a matter of time before the shaft bends or twists under load.

Trust me, there's a lot of R&D that goes into these shafts when they're designed by Garrett, Mitsubishi, and Holset- any modification would surely have an effect on reliability.

Thanks for the insight. So I guess this turbine is useless and Ill shop around for a new wheel for my 50trim. Damn rubber oil return line kink...

 

[JusMX141]

Did you price getting it serviced through PTE? May want to check before you scrap it.

Yes, if I could only explain the importance of having all turbos drain effectively....it would sure save people a bunch of money. Sometimes I wish they never made rubber drains.

 

[Leonthefaded]

Justin.

Would you consider a "knockoff" T28, acceptable after a proper rebuild? Would much modification be needed?

 

[JusMX141]

Rebuild it all you want, it's still a knockoff. You can attempt to make the reliability better by using Genuine Garrett bearings (assuming they actually fit) and having the rotating assembly rebalanced, but that doesn't mean the turbine won't snap the first time it's boosted.

Your right back to the drawing board.

 

[jmelocik]

Justin, any thoughts or information available on the turbo I mentioned in my last post? Is it worth trying to use in an automotive application on a DSM? thanks for your insight.

Josh

 

[JusMX141]

No insight- I'm completely unfamiliar; sorry.

 

[jmelocik]

ok thanks. The research continues!
