Understanding T3:T4 turbochargers 

Thank you Floyd!

P.S. That thrust bearing explanation was awesome as well!

Thanks mate - much appreciate your feedback.

Glad you enjoyed it :-)

Thanks for the compliment - much appreciated. Glad you enjoyed the video.

Thank you sir!

Thanks you sir - as always its our pleasure.

Glad you enjoyed the content

Thanks for the compliment Rob - improving a setup at a minimal cost is never a bad thing. Find the right upgrade and in the right direction, and youll be ontop every time.

I have all ways wanted to know the benefits of the trust bearing being held down with the screws as I seen both . Is it just more clamp compared to the spring that backing plate has some times . Many thanks

Thanks for the comment - much appreciated .

Pleasure sir

Pleasure sir - we will do this for you ASAP. The next video is about the TRIMS on both ends of the turbo - which will be uploaded shortly.

@@TurboDirectSA 👍

Pleasure- glad you learning from the content. Dont bother with T3 or T4 product - its ancient, poor performing, and everything about them are outdated, heavy and not efficient at all. Choose a performance/race spec product specific for your application, and try stick to Ball Bearing - it will last longer, have no thrust issues, spool faster etc.

Once again - the question is very simple - "in comparison to what?" There are MUCH better options that will spool faster, produce more power at less boost (more reliability), and less heat. The compressor stage is more efficient, and the power curve will be more linear. Lastly at similar money to the antiquated T-series models. Its a no brainer really.

Pleasure sir

Trims are essentially one part of a formula to calculate the size of the turbine and/or compressor wheel. Housings come in various sizes and shapes, some match OEM flanges, others don't - 99% of housings on performance turbos off the shelf (excluding custom made products) will not fit OEM flange faces and will almost always require fabrication to fit the desires application.

Air research was the original name before Garrett - very old designs, very well made and worked exceptionally well in the day.

Hi Alexander - what dimensions are you looking for?

@@TurboDirectSA i searching for the lenghts neck to neck and thread lenght to make sure it fits My china made bearing housing, Diameter seems to match with 10.15 and 6.3 but i dont found the rest, I want fit an mamba 9 Blade turbine wheel, ind and exd match up too

@@alexanderkringsberg2543 Shoot me an email on info@turbodirect.co.za - I dont like helping the cheap junk chinese rubbish products to be honest with you but ill see what i can do for you.

Wishing you all the luck with your project - keep us posted.

The most common "diagnosis" is that "your seals are gone" - this is most of the time a mis-diagnosis for an installation that has problems. Look for restricted oil drain, oil drain installation at the incorrect angle, breathers are blocked, oil level too high, blow by in the engine, sump pressure etc.

No - Stage3 in someones books means one thing, and stage3 in another persons books means another thing. We work on inducer and exducer sizes to be accurate - now having said this, as per the video - there are many blade derivatives with the same inducer and exducer dimensions, so what do we label these as??? The video covers the fact that T3/T4 units are in essence a fallacy due to the thousands of variants that exist .... each combination will yield a different result every time. We prefer to understand what it is that our customers want for their specific application and we build it accordingly. This way you get what you expecting in terms of response and power.

If you are looking into purchasing a Genuine Garrett GT3582R turbocharger, im afraid that you will need to decide on something very simple - a flange design. One is small and made in the T3 family, and is single scroll - The other is a larger square flange and twin scroll -called T4, choice is yours depending on what the application is. T3 will spool faster than the T4 - thats pretty much the jist of it.

@@TurboDirectSA t3 or is then. Thanks!!!

@@RaceMentally Glad i could help

Ofcourse we can - shoot an email off to info@turbodirect.co.za

The idea is more about what combination to use and what will be reliable together. There are so many other products that are better in every way than a T3/T4 - and reliable and serviceable aswell.

We should be able to yes - do you have the part# off the name plate?

For those with only budget available to them or at least a limited one - we have something for you - watch this space it should be released before the end of 2020.

@@TurboDirectSA This did come true! :D

No not at all -- the shops (specifically locally) are using cheap chinese knock off junk which come from china and are called T3/T4 Trim57 and and and -- the biggest load of rubbish.. Many clients would call us and request a T3/T4 which they heard about or saw advertised locally (in our country) and say that these turbos are great, and make power, and spool fast -- our natural response is "In comparison to what?" When we show the client the difference on dyno graphs and take them for rides in cars with the same family size unit assembled by us or off the shelf form BorgWarner or Garrett, they cannot believe the results.

@@TurboDirectSA i recently bought a garret ball bearing t04e 50trim. 48ar from a local shop in California. Now you have me doubting if its a real garrett ball bearing I know that hit side can be source out. But mainly is the internals. Is there any way to verify it without taking it apart? It costed me alot. Paid for antisurge housing and rear v band.

@@dangerousfandango5943 Firstly im not aware of a Genuine Garrett BALL BEARING T04E 50trim turbocharger. I have been the Garrett master distributor for almost 15years and never seen this turbo or heard of it. One thing i can tell you that was happening in our country was that we used to supply the "turbo guys" locally with parts to build up turbochargers including end housings and all the internal parts - and some unscrupulous companies in South Africa used to purchase these cheap chinese knock off turbos and replace the end housings with Genuine Garrett units, and when the turbos failed, the clients came to us claiming warranties -- you can imagine the mess. Im not saying that this is what happened with you, BUT in order to verify if the turbo is in fact genuine or not - you need to take a pic of the name plate on the turbo, which will relfect 100% identically to the sticker on the box and send this to me - i will get it across to Garrett for you and copy you in on the mail - Garrett will verify whether or not it is in fact genuine or not. Im doubting whether there will be a name plate on the turbo or the box - however if there is - you will have your answer directly from Garrett themselves.

@@TurboDirectSA thanks for the info. Give me your email. Ill send u pictures. Im kinda thinking the same too now.. cus the turbo was offer in journal bearing.. but optional for ball bearing also for like an additional $450. And i looled on alot of sites and they all offer just about the same thing. But can u actually built a t3/t4 50trim t04e in a garrett ball bearing? My understanding is that its all piece together.. my turbo only came with a name plate on the compressor housing.. but it seem like the numbers are etch off.. and to seriel number on the garret box. Since t04e is such an old design.. is it posible they do use garret internal amd just whatever housing they have .. ?

"Out blow my buddies little sister" what ? 😭🤣

LOL - glad you enjoyed it.

Sorry you never learnt anything - thanks for the comment.

T3/T4 technology is ancient and performance and reliability cannot come close to the newer bearing system technology of today. There is alot more that goes into a successful turbocharger than a compressor wheel.

@@TurboDirectSA of course this is dated technology and its performance is inferior to a modern design but i cannot agree about the reliability, the good old tried and trusted T3/T04 would had never managed to be so successful and universally copied if it was an un reliable design.

@@aftastosk6016 Outdated by more than a decade + >> Reliable?? Which one of the T3/T04 combinations are you referring to as being reliable? As the video shows, there are literally hundreds of options/combinations, and 99% of them are unreliable due to mismatch rotating assemblies. The point on T3/T4 models is simply this - they are old, unreliable and do not perform due to the mismatched combinations being used out there. The builders of these (predominantly the chinese) claim that they make power and spool fast, when in fact these have never been compared to anything (apples with apples) to justify these claims. T3/T4 is as dead as the DOS operating system is.

@@TurboDirectSA The NON chinese T3/T4 is far from dead on the market. Apart from the fact original Garrett T3/T4s are still available and can be easily purchased from the internet in many well established e-shops that I would never think that are cheating (ATP, turbokits, FullRace, just to name a few), NON chinese copies and derivarives of T3/T4s were the backbone of the products of well established companies (like Precision, Turbonetics, just to name a few again) and there are still on offer on the market. So dated yes, but far from finished as a commercial product. Also, T3/T4s of various versions had been used in the past on racing with great success. The fact that they exist horrible chinese knock offs that are totally unreliable does not make the basic design problematic. The fact that some of them are offering weirdo combinations of e.g stage III turbine wheel with 65/91mm wheel that Garrett didn't intended to is not a design fault. Every type of catridge, even a G series, can be the victum of a missmatch, and I don't think that if somebody is going to install a 770 compressor wheel into a G25 is going to be any different than the unreliable T3/T4 combinations. Finally, the issue with the small shops. You know very well that sometimes they do unfortunate things. The conversions of the T25s (or T28s/GT25s etc) with GTX wheels is well known, basically aiming at the Nissan aftermarket - 200SX/Silvia - S13,14,15, 300ZX and skylines - as well as other weirdo combinations of e.g. GT2876 converted with a GTX wheel...it's not the fault of the basic design of Garrett, neither the newer ones or the older ones like the T3s, that these combinations can potentially be proven disastrous. So in my final answer is THE COMBINATIONS THAT ARE INSIDE THE DESIGNED PARAMETERS THAT THE SERIOUS MANUFACTURERS AND WORKSHOPS SHOULD KNOW. And if someone has installed a genuine T3/T4 and uses it inside its limits (which are much lower than these of a G35) the turbocharger is RELIABLE.

@@TurboDirectSA I should point out that I have no connection with the websites or the companies above mentioned, so I don't have any commercial interest from the above written arguments.

Ofcourse - its a per-requisite.

I think this man is a genius! If you ever met Chris, you would want to plug into his head and download everything he knows. This video is brilliant in educating the naive people to stay away form the shops selling these T3T4 turbos - educational at its best.

nothing hypocrytical in this video - just pure facts, and physical video proof educating the everyone about the truth into what a tee free tee faw is about - and how old and poor performing it is. It's a pity that the public have been misled about this for long and spend hard earned money on this 'product' for so long.

@@tubellosefakho Nailed it!!

@@TurboDirectSA Thanks to Chris i saved money and never looked back but not on a T3 T4 turbo. His knowledge isnt equalled anywhere in our country thats for sure.
