RB and Pure unreliable turbos according to you eh?

This is stupid. You honestly trying to make this point? Do RB and Pure fun constantly on 20psi+ ? Yes, they are UNRELIABLE compared to OEM TDO3.

lol, ok according to Freur our resident know it all. Lmao

Wastegates were completely shot on my stock untuned turbos at 117k, and rattle fixes didn't work, lmao

Obviously the wear and tear on turbos is affected by how you drive, how long your on boost and what psi you pushing the turbos etc, if you push them well past 20psi constantly then obviously going to wear oit quicker. Yes you keep telling us boost has no effect on turbo wear, lol

Throwing red herrings like accusing others of being a know it all, doesn't prove anything.

RB and Pure turbos are quite reliable, of course Feuer will tell us Stock twins at 20psi+ is more reliable, lmao.

Not to be inflammatory at all, but it appears you don't have experience with the assertions you're making, whereas feuer has a good bit of personal data to back up his position. I tend to think RB is the best you can do for a reliable, higher psi setup, but how many miles have people gotten out of them? I just don't know. The stockers seem to be good for tens of thousands of miles, even when being pushed to 20psi. We know this from all the data we have on them. They are fairly proven in this regard. What isn't proven to me is the long-term reliability of RB's. Maybe feuer has more data on that. That's what I'd be asking him. He doesn't strike me as the type of guy to just make stuff up, so I'd like to learn a thing or two from him. And about the psi design of the stock turbos, we both know BMW doesn't make them, so it's pretty irrelevant what psi BMW chooses to run then at. BMW had many reasons for choosing 8psi and I wouldn't be surprised if the psi design of the turbos wasn't one of them. But if feuer can back that claim up, we all learn something together.

I guess my bottom line here is that feuer knows his stuff with these engines, and he didn't just learn it from a book. He fixes stuff and breaks it again. I place a lot of value on that kind of experience, so when he takes an opinion on something, I like to listen and try to learn.

[stewbets]

Looks like feuer already offered up some data in the time it took me to type that. This is the kind of stuff I like because I want to learn.

At least I know basic math and can figure out the difference from 8psi and 16.5psi for TD03 turbo mounted on same 1.5L engine displacement. Can you please go again now? Please reply how TD03 was made for 8psi. I would like to have a good laugh again.

Yes, I did. They are many reasons why TDO3 reaches its peak at 20psi on n54. On other platforms, like on Honda I used for reference, they peak out at 28-30psi when tuned. BMW set them to run at 8psi deliver, smooth, liner power that won’t outperform the m3. Not because TDO3 is only good for 8psi. Is beyond stupid to think that.

Well done, lol.

That wasn't the point though,

Claiming you can rinse stock oem turbo's at the 20+psi and they won't fail or reduce life expectancy of turbos is.

It was set at 8psi for longevity,

Stop writing and embarrassing yourself further. We all know your level of knowledge on the subject.

[TheMidnightNarwhal]

So, from reading this, then might as well get OE turbos from FCP that way I have lifetime and can run 20PSI sometimes when I want and be good? (sorry for thread jack, wasn't sure if I go OE or upgraded but reading this info from from Feuer makes me see OE turbo as a interesting option even if I want to do more power sometimes)

Lmao, bmw set them at 8psi, even if I agree they are good for 16.5psi, it doesn't mean you can ass rape the turbos at well over 20+psi like you said and then claim the life expectancy of the the stock turbos isn't reduced.

What is wrong with you? Where have I wrote that? Stop making things up! I could care less of what you agree or not. Fact remain the same: you are clueless on the matter.

Read your own posts, you backtrack, throw red herrings about, typical of Freur antics. likewise I don't care what you think either.

It appears to me that you suffer from hallucinations. Why are you back paddling from post #118 ? It will go down in history as the ultimate false info. Design for 8psi. I’m still laughing about....

Does anyone know if you can complete the front actuator repair using Rhinoramps/vehicle ramps instead of jackstands with wheel removed?

[R3dLeader]

Whatup rattling fam. Checking in late 2022 with killer wastegate rattle at 55900 mi. Bought the car with 49k miles, noticed slight rattle. Put catless downpipes on and the rattle got worse. Tuned stage 2 and the rattle got worse to the point where I started researching eBay 17Ts and RB Turbos and watching DIY subframe removal videos.

Finally went after this quick fix last night. Needless to say, I no longer need to shop for new turbos (for now).

For some odd reason, I started with the front turbo. Put 1 washer behind each bolt. These are thicker than your average washer, so roughly equivalent to 2 standard washers. It got dark and I didn't have time to attack the rear turbo. Started the car and the rattle seemed better, however upon a test drive it was pretty much exactly the same as before. Was my one thick washer not enough?

Fast forward to tonight, I adjusted the rear turbo arm two full turns tighter. Didn't touch the front. Went for a test drive and voila, silence. It was so beautiful, especially in an e93 vert. So how long will this last? Let's see....55900 miles, day 0.

I almost want to remove the washers from the front turbo so as not to cause any additional strain on the wastegate bushings. Although I do think I noticed a slight improvement in the rattle after doing it. Darn placebo effect!

Anyhow, the job is not difficult at all once you poke around a bit. To the guy above asking about ramps (like a year and a half ago), sure you can do it on ramps. No need to remove the wheels.

Hi fellas, I just found this fix, I was wondering was anyone able to revive turbos with this trick? My car is not making boost at all and has the obvious wastegate rattle. I was able to test vaccum and the rear turbo wastegate fully closes at 7 but I was unable to see the front turbo. Thinking of trying this trick with hopes that I might get a bit of boost back.

FWIW on my 148k turbos that rattled like mad spacing out the actuators improved my spool by approx 1k RPM (in 4th at WOT) and brought the boost from 15-16 to the full targeted 18psi.

They have since started rattling a bit again so it is only a short term fix.

Guess it might be worth trying it. Thanks!
