Everyone knows this. But the price is too high for the minimal gains. To re-iterate, BNR is taking a k04, gutting it, and then replace the full internals(intake and exhaust wheels, bearing and shaft) whith those of a GT28. Essentially its a GT28 in the form of a a k04.
We all know that testing is required and all that jazz but this guy has a great track record doing this for years on other vehicles, successfully. The mazda guys love him and their k04 is almost the same as ours.
Cant wait!

, the gains will make the btf wheel upgrade look like a joke 
3 stages. 2860 stock compressor housing, 2860 upgraded compressor housing/actuator, and the 2871 with upgraded compressor housing and actuator. I haven't gotten to the point of prices just yet. Just making sure all machine work is done properly before I get too far involved.
400 BHP shouldn't be a problem. I am not using the K04 turbine wheel so that won't be a restriction.
Word through the grape vine is around 1250 for it ... not too bad for another hundred horses or so.
We gotta see numbers before we buy.. Already recommended it.

Please don't white wash all forums this way.
I am admin on a forum that is nothing like this - then again we also clearly state that we're user supported, and no one is profiting of the site either... we don't even have advertisements(!)
If you don't like the forum you're on (which ever one that might be), by all meants find another one ... lnf performance maybe?
FYI: I just tried, and it looks like the BNR site has server issues at the moment.
I know that I would be interested in something like this... especially since it's technically not an aftermarket part
(it helps that I too have a spare turbo here)
I'm glad to read that Brian has replied, and that HHRsouth is on the 'to be notified' list...

So far every single K04 upgrade or hybrid for the factory K04 has started with posts in the Kappa platform forums, the K04+, TD05 hybrid along with a few others variations, including BNR Racing's idea.
I'm also the one that posted about the new Mitsubishi LNF Regal Turbocharger as I'm the one that actually physically has one in hand. It is a LNF turbo made by Mitsubishi, its uses the LNF flange. By the way my original thread on it ended up in the resulting of other members having the insight to find a bolt on Forge bov for the BW K04 (great job to those guys).
BTF (Bald Turbo Freak) has gotten back in touch with me and told me it was the new 2011 Regal LNF turbo also, now if you know more about Turbo chargers for the LNF platform then him, please let the rest of us know.
Some people just want everything handed to them without doing anything and then bitch when they get it. You should just be lucky other members of this forum are doing the leg work for you so you can enjoy upgrades.

i sure hope this works out. Has anyone else ever noticed that anyone that has put a different turbo on the stock manifold has had lag issues? I honestly don't think this stock exhaust manifold can flow enough to make good numbers down low. im hoping since this is kind of a stock turbo it will be better.

its just some food for thought. I have a precision 50 trim and it takes FOREVER to spool. I have done research and Badbaltguy, FF ACE, PT5457, and Boostking were all on stock manifold but slightly bigger turbo and they just wont spool up. But when switched to an aftermarket manifold they suddendly spool up like they're supposed to. I have done everything to get this turbo to spool faster from tuning to shortening the wastegate rod as short as it will go.

so don't be suprised if you guys buy this and it wont spool up until about 3000 RPMs and get full boost at about 4500 RPMs. My setup is easily at 400whp but anything less than 4000 RPMs and a Prius could probably walk me lol

I guess it all depends what you are trying to achieve. Im not sure if I want the slightly slower spool and more top end of the 2871, while also needing a BOV, or the faster spool and slightly less top end of the 2860, keeping the stock BPV and not having to mess with a BOV.
Decisions decisions....

I think the 2860 and 2871 both with upgraded compressor housings would need aftermarket BOV but the 2860 in stock housing keeps stock BPV from what I understand, eliminating the need for a BOV.

I loose so much efficiency up top and that is where I tend to be falling off .. I want it to be efficient till almost 7k at least ..

You would spool about 700-800 RPMs sooner.

No, they really aren't efficient or long lasting. You obviously have no experience servicing turbocharged engines. Mitsubishi has tons of problems with their turbos, most common being bad turbo seals which cause oil burning. Evos go through oil faster than they go through fuel.
GM chose Borg Warner for the SS LNF for a reason, they are one of the top quality turbo suppliers in the world. Borg Warner is a German company, and quality is number 1. Mitsubishi has quality listed somewhere around job 1000, which comes somewhere after make lots of money selling junk products to gullible idiots.
Turbo failures of the K04 are rare, you will see a huge spike in turbo failures when these new Mitsu turbos come out though, unless they have improved the quality of them somehow.

So in a sense I kind of want it to fail but it wont .. Damn German turbo and your superior build quality

exactly. so we'll find out if the problem is that the stock manifold just doesnt flow OR if it being setup for a twin scroll turbo makes it now work very well with a single scroll turbo

I'm guessing that even with a twin scroll setup, this will probably be hitting full boost at 3200-37. Also, you guys are going to be losing some torque too. That is my guess. 400whp is a possibility before running into the DI fueling problem, even if Vince from Trifecta has found a work around. Someone needs to unlock that **** already. Guys i think I would be happy with 400whp if I still had my SS/TC. What is the point of more in a FWD car. Think I should ditch the GLi and get a Sky Redline with this upgrade????
