Questions for Justin...

[JusMX141]

You can put whatever HX40 turbine housing on that you want, but lots of guys with divided T4 manifolds prefer the 17cm T4 housing. Not sure exactly what housing you have there, but it may be worth marketing separately if you're not using it.

Hey I have quick question about this oil feed line from RRE. My roommate had a hole in his feed line so ordered a SS replacement. My question is the hole on the banjo bolt seems really small is this really adequate enough to lubricate the turbo? Its a stock T-25. F

the stock line has a restrictor just as small built into it in the area where it bolts up to the engine, i forget where but there was apick of it somewhere in one of these popular turbo oiling threads i think (it's one of the more poplular theads anyway) but if you look right where the T25's OEM line bolts in there's a restrictor plug looking thing in that hole.

So the short answer is Yes! You can use that and be just fine

 

[JusMX141]

The T25 has a .070" restrictor built into the fitting at the filter housing.

If you replace it with a line that doesn't have restriction, you'll likely kill the turbo. Likewise, if you replace it with a fitting that has a restrictor that is too small, you'll do the same.

Run a 5/64" drill bit through the hole and verify that it's large enough....then run it.

Justin,

I have a 5031e with a precision .63 housing and internal wastegate set-up. I also have a 3076r with a precision .63 housing. Would I be able to remove the internal wastegate set-up ie, flapper, arm, and gate from my 5031e and use it on my 3076r? I do realize an external gate would suit the 3076r better but I'm just wondering if this can be done.
Thanks!

I Just looked inside the oil feed hole on an ebay turbo, and two MHI ones.



ebay. I guess that's just a job security mod.

The housings are not interchangeable, and normally when a housing is modded to accept an external gate in some way, it cannot be easily changed back to an internal gate setup. I don't know exactly what you're working with, but I'm going to say it's 95% not possible.

Thanks Justin guess I will probably invest in an external setup prior to running the 30r.

Hey Jus I have a quick one for ya... I have a MHI small 16g 05200.. it was in ok shape I rebuilt my motor so I fig i do the same for the turbo so I got a Kamak Dynamics kit.. did it put it all back togther
ran my motor for a little had to pull turbo then I spun the wheel by hand make sure everything was ok and it spins ok and then its like i feel a little ruff spot what would cause this.. its as if the turbine wheel has Resistance but I dont see nothing rubbing ??/ thanks

 

[JusMX141]

Wider thrust collar from the Kamak kit is dragging on the center housing. I've run into this before which is why I'm not a super-huge fan of recommending this kit for use in all TD05H turbos as it may require some "massaging" of the center housing a bit.

 

[91whiteGSX]

Oh ok I c ... so should I put it back togther or should I order a MHI rebuild kit.. ??? thanks for ## time !!!

 

[rr06rs]

Do you have any specs on the hx50?

[H@xtGSX]

Justin, I bought a 20g through Craigslist, against my better judgement, but the price was right at the time and it sounded good. What I received was a GSP Super 20g, supposedly rebuilt with Mitsu internals, and wheels that look sandblasted. I believe this was a blown turbo and the guy I got it from rebuilt it, as he stated, but I ran into something on a Honda forum when I looked up the guys name that threw some serious doubt into the integrity of the seller. Is there any way to be sure it was rebuilt with Mitsu internals? And are those sandblasted GSP wheels a serious concern? They aren't damaged at all, just rougher from the sand. Thanks.

The problem lies only in the thrust collar's diameter. You'll either need to carefully dremel away some of the step on the center housing just above the bore where the thrust collar goes, or you can just run the old thrust collar if it's still good (not worn or split).

None, sorry. I can't think of a single person who has ever used one. It's older tech, so beware that it may be no more potent than the newest-tech HX40's.

If you paid with Paypal and the turbo doesn't fit the description whatsoever (i.e.- it didn't state that the turbo was a rebuilt knockoff), I'd file a claim and send it back.

You can't rebuild a knockoff with all Mitsu internals unless you have access to oversized seals and bearings. That being said, it either doesn't have Mitsu internals or they just rebuilt the knockoff as-is with more knockoff parts (shitty).

Unknown parts, unknown rebuilder (who knows if it was done properly)....that's a recipe for disaster.

Actually, the reason I was asking was bacause I came across one for very cheap and was considering having a 52 pro wheel oil in it. Any thoughts or concerns? I'm currently running a custom h1c/hx40 super in a machined .69ar FP housing and it kicks ass. Just looking to try something different for the 800-1000whp range that'd be somewhat responsive.

 

[H@xtGSX]

I have a few more days to file a dispute, but I want to make sure it wouldn't be rejected on semantics. Does Mitsu make oversized internals that large? I have a micrometer I could verify dimensions with. I am kicking myself for buying this thing already... And I knew I shouldn't have.

I have seen oversized bearings, but it is the difference between a real Mitsu TD05H shaft (which I have a 14b for reference), and the larger sized shafts the Chinese companies are using to compensate for lower quality steel, right?

No clue, mainly because I don't know how much turbine flow is needed to make a HX52 wheel perform on a 2.0. It could either work perfectly or be a laggy dud.

I'd have to measure both and post back, but it's a significant difference. The knockoff shaft's dimensions are identical to a T3 Garrett because those made at the smaller TD05H shaft diameters all broke due to the shitty grade of metal used.

A simple way to tell is if you pull this turbo down and the shaft is much bigger than a 14B shaft, the seller is full of shit because you can't install Mitsu parts where they won't fit.

 

[H@xtGSX]

Ok. That's what I needed to know. The 14b is sitting right next to it now, and I have a T3 to reference also. It is already popped open so I just need to go measure it. I was looking at it earlier though, and I made a mistake in my initial judgement of it. It couldn't have been a blown turbo. Everything in it is new. It wasn't sandblasted. It is a cast compressor wheel. It has also been balanced. The reference marks are still on the wheels and there is some slight grinding marks on the base of each of the wheel nuts. All the housing clearances are actually just as tight as my MHI, and the journal and thrust play are actually tighter by quite a bit, but still very smooth moving. I also checked the wastegate (actual 34mm, and smooth), plus the turbine housing casting is very professional and flange face milled flat. I would use the turbine housing without hesitation. If I didn't know anything about metallurgy, I would say it looks every bit as good as a real MHI unit and would probably already be running it...

 

[JusMX141]

Definitely snap some pics if you would. They often tell quite a story to an experienced builder.

 

[H@xtGSX]

Pics of wheels and housings. Measurements are approximate, as holding the mic in one hand and taking a pic with the other makes for crap accuracy. The nicks on the turbine flange were my fault. I knocked it around a little seeing if it would fit without major hassles when I got it.

I didn't disassemble it because if it is balanced, I don't want to mess that up. I used a endoscopic bore scope up the oil drain hole to look inside. All the surfaces looked unvarnished and clean, and all of the observable surfaces were free of any sign of rotational wear. I can't take pictures with that though.

I guess the real questions now are if I were to keep this and it failed, can it be rebuilt to be as reliable as a MHI or Garrett? And would it cost a fortune to do so? Or is this always going to be a major liability, and I should cut my losses, get a refund or file the dispute, and just eat the cost of shipping it back?

In all respects though, it is a nice *looking* turbo. The Chinese quality is definently improving since I last saw one.

It just looks like a new Godspeed turbo- it appears new and doesn't seem to have ever been rebuilt. That's not a MHI TD05H turbine wheel. The turbine inlet flange appears to have been drilled off-center which seems to be the norm for junk sold by Godspeed Project.

Disassembly doesn't matter as long as you line the marks back up when it goes back together. The lack of any wear marks or heat discoloration anywhere further prove my point of it being a new turbo, not a rebuild.

It's clearly not as described, so the outcome of the transaction is up to you. I don't know what you spent on it, but they sell around $350-$400 new.

If it were possible to turn this into a MHI 20G, you'd spend almost $400 on parts, labor, and balancing. So $400 additional spent on a new $400 knockoff to maybe have a turbo that will be as reliable as a MHI unit doesn't seem like a major bargain.

In all respects though, it is a nice *looking* turbo. The Chinese quality is definently improving since I last saw one.

Not long ago I saw a nice "looking" TD06 20G that appeared to the just like a MHI unit in every way until the owner made boost the first time and the shaft snapped. The compressor wheel hit the housing with such force that it literally broke the housing.

...and that was the very first time it made boost.

 

[H@xtGSX]

Yup. That about covers it... I can't risk a catastrophic failure. My wife would murder me because of the down time... Mainly because I have just spent an excessive amount of time rebuilding my crankwalked 7 bolt, which I will probably also have to replace again in a while also. I bought it for $300 because the seller mis-quoted me at first and I held him to it. $50 saved isn't worth the potential damage. I always feel like an idiot when I make impulse buys, and this one is no different.

Looks like I will be shipping it back tomorrow and bolting on my good old 14b again until I can find a real upgrade.

Thanks Justin. I appreciate the help.

 

[JusMX141]

If it helps, Godspeed offers a warranty....but probably only to the original owner.


Do you want a turbo with a compressor outlet facing the passenger's side like that? If so, PM me and we'll talk.

 

[H@xtGSX]

...and I doubt they warranty the motor it is attached to if it grenades or shaved the bearing metal off into it.

I am doing the dispute right now and packing it up. I want a 20g, and I am inclined to get one of the ones I saw from you that was a TD05h with the 16g size compressor housing for ease of installation. I will PM you when I am done with this other BS.

 

[eclipsemf]

What turbo rebuilt kit is needed to rebuild a PTE 3431E with a 3" inlet ans 2" exit.

Thanks!
