Questions for Justin...

[okm12346]

I just got this s16g with fresh rebuild on it. It spins freely and it has no shaft play. The problem is that when I start the car it spins free a second and then it completely freezes. I can barely turn the fins. I turn off the engine and I can spin it again. Another this is that theres no oil coming out of the oil drain.

Whats wrong here?

My 6152r has started to smoke and has quite a bit of shaft play(wheels aren't rubbing yet). So looking at my options. My first question is I have the T3 housing with a 4 bolt 2.5 outlet. If I find a gt35r will my housing bolt up so I don't have to change o2 setups? It looks the same and number of bolts are the same but not sure. Also had thought about having my turbine housing machined for an HX35 or 40. Just looking for similar power levels without having to change my entire setup.
Thanks

just picked up a used PTE 50 trim (unsure of exact model) but im trying to figure out what i need to feed this bad boy oil

is this the correct part i need to feed it

You don't necessarily need that adapter if your inlet flange is threaded...just buy a 4AN adapter for whatever size your inlet threads are (1/8" or 1/4" NPT).

i can either run from the head or OFH whichever you think is better just trying to order all my parts at once

or should i use these?

Definitely feed from the filter housing, use a restrictor if necessary to bring pressure down to 70psi or so at peak.

Hey Justin. I'm putting together another compound setup. Goal is a small 16g or 14b with an hx40. Would you recommend a six blade hx40 or maybe a batmowheel setup? I'm having a hard time finding anything but 8 blade 40s. Even goldfarb hasn't been much help.

May as well use the largest and best-flowing HX40 available if you're going to have a smaller turbo feeding it. It's difficult finding them, I know this.

Doesn't sound like it was rebuilt too well if it's locking up and not passing oil. About impossible for me to pinpoint what's wrong without having the turbo in front of me. I'd be looking into returning the turbo to the seller if it's not working and it was described to be in rebuilt, working condition.

Not sure if there are any 2.5" outlet 35R's out there or not....but you can definitely get your housing machined to fit a HX40- it won't work on a HX35 as the 6152's turbine is already larger than a HX35 turbine.

How does the toyota ct26 off a 92 all trac compair to a t-25 or 14b?

I got a buddy with a cellica and i think specs are a 45.5mm compressor. But the compressor housing looks like a much larger AR. Almost like a down firing 20g comp cover size.. Just curious .

 

[phunny]

I have 2-ct26's in the garage if you need any info off of them, a 20g is an upgrade compared to a ct26 though.

 

[JusMX141]

CT26's are horrible in stock form- they could definitely benefit from a compressor upgrade.

 

[Archer Fabrications]

Yeah my buddy at welding school has a cellica with the turbo motor and stock turbo. Swapped into a non turbo body. Kinda funny. What should i recommend for a compressor upgrade to him?

I thought the compressor looked huge for a stock turbo. Apparently 14psi is almost maxing it out and stops pulling at 5k

 

[JusMX141]

Depends what boost level he wants to run and how much power he'd like to make in doing so.

 

[Archer Fabrications]

Yeah i guess, no clue what he wants, i told him the next step up was an 18g

Justin, I was in the finishing stages of my Big T28 Turbo rebuild. I wasnt able to fully seat the turbine shaft into the CHRA because of the new metal seal on the turbine shaft from the rebuild kit FP sent me. I tried using the old seal but I realized that the seal was no good.

Have you ever come across this issue? What did you do?

My head is against the wall on this issue. I do not have any photos unfortunatly because my phone was broken last night before I could post this with the references I am describing. I have found an ebay seller with T25/T28 Shaft/Turbine's but well you know that is.

I beleive I am left with few options.
Purchase a new turbine shaft
Find a seal that fits
Run the turbo with the turbine shaft seated improperly
Purchase a new/different T28 or go for a 20G (Openport is being delivered to me and I have evoscan)

Your input and help is appreciated

Whats the nut size for the exahaust manifold..3 bolts and one nut,im missing the nut.

Your turbine sealing ring groove is pinched shut from excessive play allowing the turbine to rub the center housing. The center housing may be wiped out, too.

Sometimes you can open the sealing ring groove back up with a thin file if it's not too bad, but you really should replace the turbine.

Have you ever come across this issue?

All the time.

What did you do?

Either replace the shaft if the center housing is good, or replace the CHRA/scrap the turbo.

I have found an ebay seller with T25/T28 Shaft/Turbine's but well you know that is.

Won't work- your turbo is neither a T25 or T28....it's a Garrett TB2578. Parts are quite scarce.

Whats the nut size for the exahaust manifold..3 bolts and one nut,im missing the nut.

10mm x 1.25.

 

[Bud92gsx]

Not that one,,one of the 4 that hold manifold to turbine housing..My bad.

 

[Leonthefaded]

Thank you justin! Your expertise is always apprreciated

 

[JusMX141]

I should add....the TB2578 combines the good 'ol T28 compressor we all know and love with a GT2560R-spec turbine only in journal bearing form. If you can find a turbine from a journal bearing GT2560 used on some Isuzu trucks, it will fit your turbo...but that's not going to be easy. Plus the GT2560 uses a different compressor than the TB2578, so don't think you can drop a ball bearing GT2560R CHRA into your housings and be good to go- it will only be half right.

This is all shit I've learned the hard way after being in a similar predicament with an identical turbo years ago- so consider it factual.

 

[Leonthefaded]

So here is what I did. I used my dremel and a grinder attachment to make the seal smaller and also the hole bigger for the shaft, and the result was good. I'm going to put the turbo back together and see what happens. If it fails the worst that can happen is I blow a lot of smoke during the test and I have to uninstall it and reinstall the stock turbo again. But I have confidence in the seal holding good.

Down the road though, if I should so happen to rebuild this T28 again (assuming its successful) I will have to make sure the seal is the same tight fit.

 

[JusMX141]

Use a short piece of hose, blow a light amount of pressure into the drain hole in the cartridge after you get the entire turbo assembled like you're blowing up a balloon. There should be a decent amount of resistance and the majority of air should exit through the inlet hole- if it exits out the turbine sealing ring immediately with little resistance, you're screwed....oil will dump right out.

Quick question Jus - SCM6152E DSM bolt on hotside - is it worth machining, or even possible to machine, to fit a 7 blade HX35?

I briefly remember this coming up in the past, I think it was the PTE's that use an offset volute similar to Mitsu hotsides and it's nowhere near as efficient as the BEP center volute?

 

[JusMX141]

PTE's turbine housing design sucks, and the T350 turbine is already larger than a HX35 turbine (62mm vs. 60mm on the exducer) so it's already cut too large.

Somewhere I remember you posting that PTE's housing's were garbage, looks like my memory worked this time.

So you're saying to machine that PTE turbine housing to fit the HX40?

T350 - 62mm exducer / 71mm inducer
HX40 - 64mm exducer / 76mm inducer​

Like it was meant to be... KIDDING.

If you didn't deduce where I was getting at with this, a local DSMer sent you their SCM6152E and he got bad news from you so I told him to ditch it and pick up a Holset with a BEP. He just wanted to know if he could put the hotside of the PTE to good use but, from the way it sounds, putting it in the garbage is putting it to good use.

Thanks Jus

It's been done (http://www.dsmtuners.com/forums/turbo-system-tech/439983-dsm-bolton-63-r-hx40.html), but the money spent on machining would be better-spent finding a good used BEP HX40 housing as you're still left with a poor-flowing PTE housing when it's all said and done.

 

[Archer Fabrications]

Justin, that hx52 I'm rebuilding, my stepdad wants to throw it on his peterbuilt semi, (currently running hx40w) would he need anything like we need to upgrade to run an hx52? Fuel mods or ecu flashing? Cause if he can upgrade then i just got me a 1000mile hx40 in trade for the hx52. I know nothing about diesel motors.

 

[JusMX141]

If it's a mechanical engine it can screw up a lot. The factory injection pump is set up anticipating boost at a certain RPM...if you make it laggier without correcting the fuel settings you can potentially make less power.

 

[blackrosenova40]

Well what engine does he have in his Pete?
