The set you have is the Costel version, there are several major problems, which I made a few videos on. I suggest watching all 3 of the videos on them because I found more problems as I was doing the rebuild. The VIV set of turbos use tdo4 journal bearings, the Costel set has an odd made up size journal bearing which uses a matching size shaft. The thrust bearing you need to use on that turbo is a tdo4 not tdo3, you are saying it needs a tdo3 because of the dowel pin location hole in the bearing. You need a tdo4 thrust bearing but the hole needs to be on the opposite side. I have been drilling the tdo4 bearings to make it work and have several on hand. The tdo3 and tdo4 thrust bearing diameter where the collar goes is a different size. The Costel turbos need a lot of things fixed on them you are better off just getting a viv set. Also those thrust bearings should never wear out at all if they are designed properly, from what I can see it look like the pattern on the bearing is for a reverse tdo4 that were in the turbo which makes sense why it would wear out because the pattern on the thrust bearing is directional, instead of the pattern on the bearing helping lubrication it’s scraping off the oil as the spacer and collar are spinning on it. I’m not sure if that tdo3 bearing will work on on that turbo or not, I think the inside of the bearing is too small for the spacer to fit.

You know what, I think I made a decision. I am going 17T. Reason being I already got 3 cars. The 335i is my daily right now but I'm probably just gonna sell one or two of my others (both are also gas guzzlers) for a reliable daily like a Camry or something then go full send on the 335i. Thank you for the video. Btw: Secret is maintenance as well on the N54. At 156k and still runs beast!

Good video. My 17t 11 blade turbos were sold to me and advertised as td04L center section. Hopefully i won’t have to rebuild them but this info is great. Subscribed and liked

Your video on this are really quality imo. You have a good understanding, can see it and can show it. N54 platform was already given a shit for quality turbo from the factory. I sold my 335i about 3 years ago so I've been out of the game for that long. Getting the car back now and over the last two days I've been playing catch up on turbo game. When I had the car the Chinese turbos for sale were all bullshit remanufactured stocks with cheap internals and billet wheels that boasted more fins for bullshit claims of power and psi. It seems that some Chinese companies have realized instead of scamming people, to actually throw a little R&D into hybrid builds. They are already the people making all these parts for name brands in the US. If they had skipped out on the cheap shit and built a true TD04 internal with the upsized housings they'd own the aftermarket turbo game. People bitch about Chinese hybrid builds but throw 25psi+ at them. They were never built for this nor will hybrid updates make them reliable for this. People expect a product to last forever even though they are moon boosting them well beyond engineering intention. For this reason I'll be buying 19T turbos (hopefully v4) tearing them down, check build and tolerance, replacing the weak parts, sending off for balance check, installing and giving them hell and reporting regularly. 15k miles out of a set of turbos you're pushing well beyond limits is a good fucking run. I'm on board with these! Thanks for the review!

good video man thanks for posting

I might be wrong but I think Vargas sells the the wheel that you bent. GLW your build.

Do you need to rebalance the turbos after installing the Turbo Labs hardware?

Can you link me to where you got your rebuild kit from please?
