So is this kit going to work on the new EFR 5951?

Yes and no. The 5951 isn't a B1-frame turbo, but it will have a T25 turbine housing. As soon as I get one, I'll start work on a 5951-specific downpipe for it.

Keep in mind that the 5951 is at least a year away from production, according to the rep I spoke with at SEMA. Think 2018.

Damn, the 5951 is going to be the perfect turbo for this.

Sounds like 2018 is going to be a good time to buy a cheap turbo setup!

Spoiler
When everyone offloads what they have now for the 5951 setups that is....

When the 5951s are actually available (i.e. in 12-18 months) we can discuss them more. For now, let's keep this thread on topic (6258/6758/7163 kits).

Big batch of turbos shipping today from my distributor. The 6258s have been a little hard to come by, so it may be 6-8 weeks before I see any more. If you want a turbo this spring, I would suggest ordering ASAP

I feel like there is some guy out there in the world who randomly decides to make turbo's hard to come by. With what your hearing, currently that makes Garrett 2554, T3 ChinaChargers, and the 6258 all hard to get at the same time. It is a little weird how all that works.

Its almost as if there's a common supplier somewhere in the supply chain.

Isnt the pipe supposed to be etched, or prepped in some manner so the coating can adhere properly? Looks mighty shiny underneath.

ROFL!
I had a BW engineer design some stuff for me.....Got to meet some higher ups there....Was cool...In a very stuffy corporate culture kind of way.
That pretty much says it all about BW from my experience.
The up tight engineering culture at BW would have an absolute jammer if any tie to a china charger company was mentioned never mind existed! lol
You will never see the two together.
Those cubical kings are afraid to drive certain vehicles because of the turbo inside ...not kidding!

At one point the corporate line was that Garrett was unreliable garbage, because of the ball bearing thing...A few years later the EFRs came out and that talk has since died down.
Pretty funny if you ask me!

Yes, the EFR has a better bearing system...I just thing the whole thing is funny

FYI, Borg Warner has a lot of mfg in China. They were a substantial customer for me in a previous company.

Meh. There is nothing wrong with production in China IF you have your own people on the floor doing QC from start to finish. And thats a big IF.

I've spoken to some guys who work for companies that do this, where their own people do QC on the floor, on site, for every step of the process. I'm talking everything from the raw materials, production, finishing, assembly, etc rather than trusting the overseas manufacturer to do it correctly with no supervision. To a T every person I've discussed this with has said that China knows how to get **** done, but as soon as you look the other way, they will cut so many corners that your square product will come out looking round. A lot of companies can't afford to do this, and their products and reputations suffer as a result.

So if I start showing people my hideous turbine housing as proof of BorgWarners terrible Chinese production and QC process, and maybe they will send me a nice pretty investment cast one to shut me up?

IIRC they purchased a foundry to solve that issue (poor casting quality). All the recent housings are their new shell-mold housing which has exceptionally good finish, better than the investment housings IMO. Such is their commitment to QC.

I know of several Aussie companies who've had the same QC issues with components made in China.
It seems to be part of the Chinese mindset, to cut costs/corners wherever possible and the only way to stop is is to have their own QC guys watching every step of the process.
Until they change this mindset, China will never be a major car exporter because nobody will trust them not to fall apart or fail (Great Wall 4WDs in Australia have a reputation of stopping dead when driving across creeks, not enough waterproofing of electrical components).
Interestingly, despite QC issues in China, most prefer manufacturing in China than India (apparently the Chinese are more trustworthy - read into that what you will).
FYI: India would seem a more natural choice for Australian manufacturers since manufacturing in India is approximately the same cost-wise as Chine, we have close ties to India, we're part of the British Commonwealth, both speak English and are both Cricket "powerhouses" (Cricket is the one unifying "religion" in India).

I've got one of the original EFR6258s too EO2K and it's pretty rough, there's no way that Stage8 fasteners will fit unless the exhaust housing casting is filed down to provide flat surfaces for the Stage8 fasteners.
Since my exhaust housing was ceramic coated, I didn't want to do that and used Nissan fasteners instead (if I wanted to fit the Stage 8 fasteners without filing the manifold, I would've had to file down one edge of each fastener down to less than 1mm width to the stud hole - not sure how strong they'd be be after that, probably bending at the weakened points).
Now that I have the TSE manifold+downpipe, I've ordered a new EFR6258 exhaust housing (ie. better casting) so that I can use the Stage8 fasteners on it.
The Nissan fasteners may have been OK but the Stage8 fasteners are proven to work.

BW has serious corporate horsepower!
Once they put their collective minds into doing something there isn't much BW can't do.... and do well.

How long that takes?.....
I heard about a turbo that was "light years" ahead of Garrett in 2006-2007....Not sure when the EFR came out, but they don't move quickly!

That's a seriously good move on their part. I've seen and handled the newer housings and while not as nice as the first gen ones, they are still much nicer than mine. I know I've got one of the housings that they pushed out to "fill the gap" during the shortage after initial launch, but its just SOOOOO disappointing to see all the glorious investment cast stuff in the literature and on everyone else's cars, and then I end up with something that looks like I made it as a sand casting project in a highschool shop class. I'm so glad they stepped up and made an effort to fix the casting process.

Mine isn't the clamping surface for the fastener, its the area of the housing above where the nut and stud need clearance to actually install. I had so little room it was actually unusable without modification. That area is where two halves of the casting come together and there was a huge seam that protruded into the space that was supposed to be occupied by the stud and nut. There was no way to fit anything in that space other than maybe a hardware store cheese grade thin jamb nut. It took me several evenings of grinding with, of all things, a dremel and some surprisingly expensive tungsten cutters. Pretty pictures and reading here: https://www.miataturbo.net/build-thr...8/#post1170740 My favorite part is the void I uncovered in the casting
