Questions for Justin...

[turboglenn]

Just..would apreciate it if you could use your vast turbo part number knowledge to gimme the specs on the one i just bought

it's a PTE6776RS T3 .63a/r hot housing/ts04 cold housing, BB center cartreidge..all i know is the first part "67" is the mm diameter of inducer side of compressor wheel and the last 76 was uxhaust trim (nimor divided by major OD's)

but i don't know what that all equates to as far as compared to the old P-trim t3 Q-trim t4 turbines etc..
and what is the major diameter of the cold wheel or is THAT the first "67" part?

Part Number: PT6776R
the "S" at the end of mine means the tS04 cover (this spec is to4E cover)
Max Rated HP: 750 (i was told 1125 CFM by a PTE rep on the phone a few days ago)
Inlet/Outlet Size: 3"/2" 4"/2.5" or 4"/3"mine is the 4" inlet 2.5 outlet
Bearing System: Ball Bearing (not sure if this is their replaceable cartidge or not)
Garrett Compressor Wheel Trim: 63
Garrett Turbine Wheel Trim: 76

Garrett Compressor Wheel Specs:
Wheel Trim: 64
Wheel Inducer: 2.620" (67mm)
Wheel Exducer: 3.310" (84mm) (wow dats big!!)


Garrett Turbine Wheel Specs:
Wheel Trim: 76
Wheel Inducer: 2.920" (74mm)
Wheel Exducer: 2.542" (64.5mm)

Hey man i was told to refer to you on this one... Im thinking about buying this evo 3 16g. Problem is im not sure if its legit.

Evo 3 16g - DSM Classifieds

The guy claimed the previous owner shaved the serial numbers off when he coated it. He did say he would be willing to take it apart and measure the wheel but i was wondering what is the size of a mhi evo 3 wheel? If this is in the wrong place or a stupid question i apologize, i was referred to you.

Don't bother...it's a knockoff. Knockoff markings on compressor wheel, knockoff 12-point hex compressor locknut, knockoff turbine housing, etc. I'm sure the cover was "conveniently" shaved.

hey justin was just wondering i just picked up a s256 ett for a really good price and was wondering if it is possible to upgrade to the batmo wheel or not.

Sure- get in touch with Bill Devine and Bullseye Power.

The "76" in the turbo's model number tells us it's a P-Trim turbine, meaning there's no way it uses a true GT ball-bearing center housing because a P-trim turbine would never fit.

So, this turbo has a T3 center housing that has been adapted to use ball bearings by PTE. Only PTE can service this turbo, so be prepared to take it in the ass if something happens.

67= compressor inducer in mm.
76= turbine wheel trim.
R= ball bearing cartridge
S= compressor cover type.

I rebuilt this identical turbo in journal bearing form last summer for a local customer, only his used the T4-flanged .68 turbine housing.

hey i just wanted to have you confirm this is a real s256 ett since for some reason there is no bullseye power tags on it.

Looks like it. Again, turbo I.D. questions belong here.

 

[jakelandry]

Thanks a ton man.

Justin,
When I met you at the shootout while dave was in the staging lanes and you showed my his drain set up and I mentioned to you quick what I was doing with mine. (30psi stock bottom end 8blade 35) You kinda just had a weird grin on your face. Was that a grin of " I know how much fun your having" Or a grin of " been there done that, your crazy and will be putting a motor in it shortly" ?
I'm just curious. Sorry if this doesn't quite belong here. Its tuesday and the excitement and antilag going off 3 ft from away all day long hasn't left my system yet. I wish I could have talked to you more but I knew you were busy

 

[JusMX141]

I honestly don't remember the exact emotion, but I'd sure I was just excited because Dave was next to head down the track after I closed the hood during our conversation. Giving the $1800+ turbo users a run for their money with one of my $435 junkyard specials tends to do that to you.

I wish I stuck around longer to see the 10.02 run. I wound up running up the staircase to the tippy top of the bleachers to watch that run right after our conversation. I was bummed when he was still having issues. I saw you earlier in the day walking around and didn't realize it was you but I just had this gut feeling it was you. Big smile on your face and the bright red shirt with Holset on it. Theres something about that 6 letter word that make big money turbo guys look at there wallets and wonder what they did wrong.

haha always nice to see the big money chased down and passed with something picked from a boneyard.. to be hoenst now that the thrill of my new hair dryer has worn off i'm back to looking for a boneyard and rebuiilt 7 blade hx-35 (just can't go without that strong mid-range hit i gave up whe upgrading)

I rebuilt this identical turbo in journal bearing form last summer for a local customer, only his used the T4-flanged .68 turbine housing.

Reffering to what i've "bolded" above, let me ask you this.. since it's a normal T3 section modded by PTE,. does that mean that the shaft diameter on the turbine would most likely be the same as the shaft of all other T3 turbines?

Also have you pulled one of these apart? I'm wondering if you can remove the turbine and wheels to have them rebalanced and re-install them easily?????

What i really MIGHT do if i can't sell this turbo for the HX-35 i want is to take and mate the 67 comp wheel to an old school t31 stage III turbine and have it balanced so i can get the thing spooling a little sooner (but hopefully retain the BB CHRA)

I've already prety much figured out i could put this comp wheel, backing plate and comp cover onto a regular T3 CHRA with a regular T31 turbine/wheel and make it a journal bearing 67 - T31/Stage III, but i'd like to make that same combo in the ball bearing housing.. i know it's a horrible mismatch but with the .55 BEP housings for hx-35/40 series turbos it can't be too far off from what people are already doing... So instead of any reasons why it doesn't make sense, i just would like to know if this is feasible?

please any input on this CHRA is apreciated.. I really wanna sell it and then hit you up for a nice new HX-35 and then put the leftover cash towards some 1450 injectors, but who knows if it will sell (unless i join a supra board or buick GN board anyway ) \


thanks

So Justin, I keep finding oil like this in the turbo inlet. What's the prognosis looking like? And I have nothing vented back into the intake.

 

[JusMX141]

Doesn't appear to be centered around the compressor wheel....any chance you soak the air filter pretty heavy with oil?

Now that you say that, it really does look weird. I just threw that filter on from my Rx-7 but maybe it did have a decent amount of oil on it.

Hi Justin,
I have Mitsubishi 20g turbo installed, probably around 7k miles on it, but my rod bearings gave out. I want to clean out this turbo of chips ect.. Is there a rebuild kit or something I should pick up for this?

 

[JusMX141]

Definitely need a parts kit consisting of at least new journal bearings and seals.

 

[mattasi]

Thanks man. Is there a kit that you like or think I should get? I am not sure on good brands

 

[Zefal151]

Couple questions for Justin...

the turbo on a Hyundai sonata is a Mitsu tdo5h Twin scroll... im assuming similar if not same to the evo turbo... am i mistaken?

Im looking to go more for a DD road race setup and not a drag setup after converting to AWD, would a HX35 be a good choice for that build setup or is there a better turbo that would get me around 425hp?

No clue- I don't work on Hyundais.

68HTA would be the best choice. You'll have to pick whether you want to trade spool for horsepower once you go beyond the 400whp mark, and right at that level the 68HTA is the best combination of all three- spool, torque, and horsepower.

 

[Zefal151]

Thanks justin... that helps a lot... ive also been looking into twin scrolls for the quick spooling times as well

This is the Sonata turbo: twin-scroll Mitsubishi TD04-19T turbo... prob too small for what im looking for

EDIT: just answered my own question about the TD04-19T. "The TD04-19T compressor wheel is the most aggressive compressor available for the TD04-Class. This compressor upgrade is capable of producing 500CFM of efficient airflow at 2bar exhaust outlet pressure with a shaft speed of 150k RPM." "...successful extracting a solid 300HP and in some case up to 320HP depending on the application and turbine wheel."

 

[JusMX141]

The 19T compressor is the largest available in the TD04 platform- it's normally used on Volvo turbos. I can't honestly imagine a car that would require the spool that a twin-scroll TD04 could deliver, unless they're using some ridiculously large turbine housing spec to offset the small turbine wheel's poor flow characteristic, then making up for the added lag of the large housing by making it a twin-scroll.

 

[arturorz]

This thread is awesome !!!!

Justin...., thanks for taking the time to answer all the questions.

 

[Zefal151]

ooh i got a difficult one now...

whats the differences between a hta68 and a 20g?

how major are the differences in spool times, cfm, and maximums

 

[JusMX141]

There is no set number- the 68HTA targets the 20G's high-boost airflow numbers while spooling quicker and remaining more efficient at lower boost levels as well due to increased surface area of the blade. In terms of measurement, the 68HTA actually has a slightly smaller inducer than the 20G, while the exducer remains the same 68mm spec.

Comparison pics here.

 

[Zefal151]

man, you are too good justin, too good

 

[mattasi]

Hi Justin, I am looking for a rebuild kit for my Mitsubishi 20g turbo. The only kits I have found are on ebay and they say they fit 14b/16g/20g turbos is this right? I know my turbo is bigger than a 14b so it seams like I would need a different kit? Sorry, I just want to make sure I get the proper kit.
If it helps my 20g has a 3" air inlet.

Thank you Justin in advance.

 

[JusMX141]

You shouldn't really be shopping around eBay for turbo parts- that's mistake #1. Too many kits out there that are made strictly for the Chinese turbos and will not fit MHI turbos. I'd buy only from a trusted source- some guys have luck with TraderGreg on eCrater, but I'd recommend something with a wider thrust collar and additional oiling hole in the thrust plate for a 20G- like the kits sold by Kamak Dynamics.

If the kit is strictly for a 14B, only the journal bearings, seals, and thrust plate will fit your turbo....the compressor seal collar and seal plate are different on 14B turbos; so if it says it fits all TD05H turbos, either it doesn't include the seal collar and plate, they're giving you both sets of parts, or it doesn't fit what it says it should.
