Hey everyone been awhile since I posted here but I'm looking for some advice.
My rear turbo started smoking profusely from exhaust and has a wild whistling noise,
I have came to the conclusion that the oil seals must have left the chat, (running MHD stage 2+ for a year now). So I'm in search for new turbos. I know RB is great, but I do want the chance to make more power in the future so I am considering Ebay 17t or 19t. I also found a really nice set of custom made GTX2860r ceramic bearing upgraded MMP turbos that have a claimed 600 miles on them, I offered the guy 1k and he said he'd take it, is that a good deal? I can't seem to find any reviews on the brand. I also have seen a few Pure turbos around for not to bad of a price. Please let me know what you guys think! I need to get them on my car!
Also one more question I couldn't necessarily find a straight answer on, is it okay to drive my car even though the turbo is going out? Thanks.

You can't go with RB's because you want to make more power in the future? What? They make the Game Finishers....pretty sure they make big power. The RB TWO's will hit 575+HP, TWO plus are good for another 50+HP.

If you want something that will last...go with RB, maybe Pure if you want to spend the added money. All the ebay, amazon, VIV type cheap china turbos are total junk.

Spend some time searching the forums here....lots of great info on all the turbo options out there.

As far as used turbos go....I wouldn't touch them, not worth the risk. Most people aren't going to remove perfectly good working after only 600 miles and sell them for less than half of what they paid for them.

MMP is out of business isn't it???

Why bother with anything but RB? Proven track record, do it once and done. Boost the shit out of them and have fun.

We still have these threads???




Single turbo
RB
Pure

In that specific order.

The cost to go RB or Pure + FBOs is the same cost of a single turbo kit basically. You will not regret the single. Buy once cry once.

MPP is shit
VTT is dog shit
DAW is shit
ChinaCast no names who fucking knows. At least get them balanced in the states. They all come from the same shitty location in China. You buy a pallet/MOQ you can have whatever name you want cast on them. Some people get 10k miles some 20k, some 500 miles. It is hit or miss and seems like pure luck. A crap shoot. Given the labor involved even doing the job yourself it is hard to even suggest the China cast because of the labor and down time you will have when, not if, 1 fails. You don't want these on your DD unless you can handle your car down for extended periods of time when one inevitably fails.

At the end of the day N54 twins boils down to this, 10T wheels are stock, you are buying 19T wheels which were never designed to fit in the housings. You then ring the shit out of them to get decent numbers and you need E85 etc. because they are just blowing hot ass fucking air out of their efficiency windows which is why they all last so shortly. Unless you keep em around 500-600whp.

BINGO!!

Check out hydra performance hp series. Otherwise it’s rb or pure if you want the best

Thanks for the input guys. I was really looking to spend around a grand and wasn't planning on pushing past 550hp to the crank because I am running a 335is clutch. The only new ones I could find in that budget were the RB Td03, or ebay turbos. Other then that I found the set of used MMP turbos, the manifold doesn't even have surface rust and they are built with the upgraded housing. I also found a set of Used Pure 600 that he claims to only have 1500 miles on. Is buying used turbos actually that bad of an idea. I understand that I don't know what I'm going get and that's the risk but the prices seem reasonable. I guess I'm kind of at a loss on which way I should go, I just need to get new ones on the car before it causes any damage

[int_c0m8U$tion]

Will you be doing the work yourself? If so then grab a set for 1k with 1 year warranty from a repeatable seller on eBay and send it.

If you are paying for the labor then that changed the calculus. If it was me, I wouldn’t skimp out on turbos as the cost of labor to redo would be tragic.

I love this guys channel on YouTube so you can check out what he used (1500 I think).

Also 0-60 on youtube ran some 19t’s that seem to have held up for them that you can check out.

TD03 based RB 1 or 2 would be more than enough for upto 550hp at the crank.

Email Rob and he should be able to point you to the ideal turbo for your setup.

The problem with second hand/Chinese is your rolling a dice. You can't guarantee quality.

I'm running RB 2's with a 25psi custom E40 tune. My car weights around 3,800lbs....and with easy 2nd gear launches, I can knock out 10.90's in the 1/4 mile with 128mph trap speeds (probably be in the 10.70's with better tires and hard launches). By everything I've found online, and comparing other similar weight cars...I'm making close to 600-ish HP. RB 2's are awesome turbos

For $2K (less if you pay cash).....they have got to be some of the best dollar/quality/reliability value in N54 twins out there.

Mileage claims on turbos are sketchy and wouldn’t trust them however surface rust on the manifold can happen on some with a few hundred miles. I bought a parts car at auction that the owner only had for 2 months and drove it for 300 miles until the cabin caught fire. Sank well over 10k that included pure 600s. The manifolds on them had surface rust and everything else was spotless. I had a paper trail on the mileage and history which people don’t have the luxury of when buying 2nd hand online.

Agree with you totally, just waiting for these stockers to die lol. Then I'll hopefully be getting the OEM Billets, 400whp is enough for a daily, not looking to set 1/4 mile runs or track my car. Just replaced the starter motor which packed it in as well the steering rack.

Honestly, for daily driving the stock turbos and an MHD tune put out awesome torque numbers. I think my custom tune and RB TWO's aren't much better than stockers under 4k rpms or so.....it's when you really wind them up past that you start to realize that they pull much harder than the stockers. But honestly, unless you are out street racing all the time or making 1/4 passes....the stock turbos are awesome for what they are! I'm sure those RB billets will work great!! And if/when you decide you want more boost and power our of them, I'm sure they will handle that much better than the stockers.👍

how much psi do you squeeze out of the stockers?

Stock turbos can do ~ 20psi but they taper off up top to about 16psi
