Nowhere. 9 times out of 10 they won't last as long as your original set, and oftentimes will leak and/or smoke.
Your best bet is to get new, either 99 specs, BNR twins, or a complete single system.
If you want to make big power, shoot me a PM. My BNRs only have 9k miles on them and they'll be for sale soon......

The key to rebuilds is the have the turbos balanced. If they aren't balanced (which most places don't but TurboCity does), then they will have a short life.

I have had several rebuilt so far. All have failed within 1000 miles. The componies have been real good about it but still the process of putting them on and off is hell. I want to stay stock like. I like the responce. However 4600 for a set of new ones is kinda stiff

www.rx7.com sells the efini turbos for around $2500. They're brand new, they bolt on, and you can run them sequentially.

Hey all.
The stock turbos are pretty much throw away units. I had rebuilt them for years and they were very picky to rebuild. After so many miles the factory bearing housings deform b/c of heat generated by the exhaust. The "seal bore", where the turbine side piston ring is, is very thin metal which becomes out of round b/c of the heat from the exhaust. When they start smoking and you put a new piston ring in that groove (rebuilding), the round ring will not seal in an out of round seal bore, so there isn't a reliable seal. That is why they are not buildable.
I replace the CHRA's with new upgraded units that are balanced 6 times better than OEM specs.

You have a cosmo 2 rotor twins? It can be done but the turbine housings are too small for the CHRA's I use. it would choke at 350 WHP.
Rich wants to blow motors again . You can keep an RX7 alive with 425 whp. After that you will be blowing motors on a consistant basis w/o high octane.

I've known people who have had turbos (FD stock ones as well) rebuilt by them without problems. While the FD rebuilds never lasted as long as they did when new, they lasted a heck of a lot longer than anyone else I've seen rebuild the stock turbos so far. Heck, they about about the only place to get a rebuilt kit for the FD turbos.

2350 with a core, I dont know the price without one....also it says to run non synthetic because of the carbon seals http://www.bnrturbos.com/3rdGen.htm we just got ours back from them and they look real good. right now were in the process of rebuilding my brother 93 so I have no actual feedback on them yet but I've heard nothing but good things about BNR.

Juuust kidding . Basically, I've been rocking different iterations of BNRs since early 2002, and after nearly five years I want to switch it up a bit. Plus, I found a local source of race gas, and I want to run 25 psi
I still think BNR turbos are a great cost effective option for those running pump gas, as well as for those who want something that looks stock. Bryan, don't be mad, we're still buds in my book

I called up Bryan of BNR and spent quite sometime on the phone with him. It appears that there is quite some advantage with going with his approach. The best being, from my point of veiw, is that, with his setup, the turbo creep can be controlled. I have issue with that because of the free exhaust I put on. Given that and the fact they are a true rebuild I am thing that BNR maybe the approach to use. Anyone else run these? and got the turbo boost creep issue resolved?
