hmmm interesting stuff here. this is probably off topic, but i was going to send in my 20b turbos to have the stage 3 done.... this was a few months ago, but i was assured that the smoking problem was fixed w/ the 3's..... im surprized to hear they couldnt work out the problems w/ the 3's.... maybe ill have to find someone else out there that can give my 20b twins a little more attitude

Apparently the difference in the Stage 2's vs 3's will be spool up time.
Unless you are planning on going over 15 PSI, the stock tiwns are fine. Many people have run the stockers at 15 PSI for years without problems.

Just to clarify, "stock replacement" which is just what its being called at this time and is prob subject to change when they hit the market is NOT stock twins. They will replace the stock twins with MUCH more reliable internals. It is a totally different turbo that is entirely all new parts and they are adapted into the stock housings. Then the "upgraded replacement" is internally the same turbo as the stock replacement turbo but it has an even larger compressor and turbine wheel.

actually I was the last person to have the stage 123 from rx7 store . net.. One of the guys told me personally. He sed that the guys from bnr do good work but they take so long to do the work and people were complaining. It took me a month when i was told a week for everything. BNR screwed up alot of things with the order so they sed that i was to be the last customer with rx7 store to have bnr done. Thats just what i was told though
if you think you're going to get something on time through RX7store.net, you've got another thing coming. It is not always the builder.

Here is the deal they are no longer called stage 2 and stage 3.
The new setup is "stock replacement" and 'upgraded replacement".
"stock replacement" is basically going to be all totally new parts from the ground up adapted into the stock compressor and turbine housings (which are non wear items anyway). This will also include larger shafts.
"upgraded replacements" are going to be the same internally as the stock replacements EXCEPT they have a larger turbine wheel and compressor wheel.
They are now in the process of being tested. And a couple sets should be hitting a dyno (and pushed to thier limits) in about a month. I'd imagine if everything goes well they should hit the shelves in around 2 months. In addition, at this time there are NO old style BNR turbos being sold
Hope that helps clear things up some.

can you divulge what the expected performance increase will be for the "stock replacement" or the "upgraded replacement"?
I'm ancious to get my dying stockers rebuilt.

I dont build the turbos, I ship them out and they are sent directly back to the customer from the builder. If I was building these turbos then it would be my problem.
99% of the stuff we ship shows up on time to the customer. **** happens but you make it sound like every order we take, which is hundreds a month never show on time. I have a problem with that statment.

jason,
it was not my intention to make it seem like every order ya'll ship out is late, and i apologize if what i said was construed as such. I have no idea how many people you deal with on a monthly or even daily basis. However, I do know that there have been issues with products arriving on time.
fwiw, my order was late, but I was very impressed with the customer service that you presented me. That's why I added that I will purchase parts from you again. Customer Service counts a lot for me, no matter what you're selling.
So what i should have said is that "**** happens", just like you did.

what i was told for my 20b turbos... should be similar for the 13b:
Stage 1: The stage 1 consists of a secondary compressor wheel upgrade. The compressor cover is machined to fit the upgraded compressor wheel. The primary remains factory. Both assemblies are inspected very carefully and they are each balanced/blueprinted to spec. The wastegate is ported to 30-35mm. All bearings, collars, and piston rings are replaced. All housings are very carefully inspected before used. All tolerances are checked before assembly assuring you quality in the work performed by BNR. RECOMMENDED FOR SEQUENTIAL OPERATION ONLY!
Price: $1250 with a rebuildable core
Stage 2: The stage 2 consists of both compressor wheel upgrades. Both compressor covers are machined to fit the upgraded compressor wheels. Both rotating assemblies are inspected very carefully and they are each balanced/blueprinted to spec. The wastegate is ported to 30-35mm. All bearings, collars, and piston rings are replaced. All housings are very carefully inspected before used. All tolerances are checked before assembly assuring you quality in the work performed by BNR. RECOMMENDED FOR SEQUENTIAL OPERATION ONLY!
Stage 2 price: $1600 with rebuildable core
Stage 3: The new stage 3 consists of the replacement of the factory CHRA (Center Housing Rotating Assemblies) or otherwise known as a “cartridge†for the secondary turbocharger. The secondary cartridge is modified and adapted to fit the factory turbine and compressor housings which is a very difficult task! The shaft is ¼†in diameter while the stock shaft is 5mm in diameter. The upgraded compressor wheel flows a calculated 500 CFM. The primary turbocharger is upgraded with a t04B compressor wheel and is machined to fit the factory compressor cover, while the turbine side of the primary turbocharger is clipped to spec. Both rotating assemblies are inspected very carefully and they are each balanced/blueprinted to spec. All bearings, collars, carbon seal, and piston ring are replaced in the primary turbocharger while the secondary turbocharger comes with a new CHRA.
Stage 3 price: $2100 with rebuildable core

Lives on the Forum
So how much larger ar the T04B wheels compared with the stock compressor/turbine wheels?

Bryan came by the house to show me the completed set of upgrade twins. I took a few pics to show you guys since there were some threads about them. I started this thread for the pics......

I thought they looked awsome. Have you seen it? He'll be in B'ham first weekend of March to dyno his car with Steve. In addition I'm going to dyno my car, we're going to dyno a wicked 1st gen that Bryan just built and a few other cars. You should try to make it down
