Guys, there is a low boost dyno sheet, which yielded pretty good #s under less than ideal conditions. The race against the mustang in the kills section also gives a pretty good indication of abilities----hanging within 1 car length of a car trapping ~120 mph, this at 13 psi. For right now, that is it unfortunately. More to come soon
I know a thing or two about the stock ht12s. I ran them on my car for 95k miles. my dad has a fairly fresh set on his R1, which i still drive occasionally. I have driven many customer's and friends cars with them, prolly around 20 or so. They're not bad turbos, but most of them out there are old, tired and leaky. Try and rebuild them, and you are looking at another turbo r&r soon b/c of a multitude of reasons--absence of new parts chief among them. they aren't reliably rebuildable. So you can either go efini twins if you are happy with stock twin like power, or go single if you want race gas monster power levels. If you want a 93 octane street car that pushes the envelope as far as boost or rwhp, you may want to look to these BNRs.

Fact is rich that there are going to be skeptics until we get some evidence that they perform. Especially since the last sets failed.

I am waiting for a high boost run before i sent my cash. Rich you said u are gonna get a tune very soon. Is this a road tune or dyno tune.

The last sets didnt fail like your making out. The reason they smoked was because people dont know how to properly run thier crank case vent with upgraded turbos. The same problem has been happening to the new Garrett single turbos. The problem is crank case vent, the stock twins dont require very much crank case vent due to the seal design. They are the ONLY turbos made that use that design seal. Every other turbo requires more crank case vent. I as well as others I know didnt have any problems and a few people I talked to fixed thier by changing the crank case vent.

Plus, as someone who's always kept his eye on the BNR threads, I gotta say I haven't read a single thread where someone said their BNRs simply went kaput. They may have smoked a lot, but I believe ppl said they pulled pretty hard and were happy overall.

Now it has race plugs leading, and 10w30 idemitsu. It's like a different car.
Maybe we should meet up somewhere between CT and NJ and make a few runs.......It would be worth it just to make you a believer

Need real proof..
All I'm seeing is 10 to 15 HPs(if anything) from this hyped up BNRs over stock sequential, and, at wot which takes the wear and tear on the engine. Which means no streetable fun, nor the low rpm passing through traffic. If I'm gonna tax the engine that harshly, I'll most likely throw another grand and get me a decent single.
Computer is a must, because in order to effectively make the most out of the BNRs requires one anyway.
It'll take more than just tuning to gain that one car length. Most likely you will need another 80-100 horses to have any success. It is that much significant, and critical sometimes..

The real question, is there anyone that ONLY added the new BNR's? Not a total engine build up including them. It's hard to tell what's making the difference if more than one component has changed on a car.

Intelligent posts in this thread only guys, keep the rest of the stuff in the lounge. Thanks

I really like it. It's formulated specifically for the rotary---they claim better sealing, minimized exhaust port clogging, and superior shear stability (stationary gears) among other things. The 787B used the predecessor to the current formula.
I got mine from my homie Ari over at www.RX7.com . For a non-daily driver, low mileage machine I feel like I can justify the cost.

I think i am gonna try running 17-18psi on the stockers. i am gonna see if KD will tune me in for that...i have ignition and fuel...so why not? if they die i will buy something new...bnrs or gt 35 40. i bet i could get the stockers to make 375 rwhp with stock engine...maybe that will satisfy me. Right now i cant see removing perfectly good turbos that i currently have for these bnrs. Maybe thats whta i am missing....maybe u only buy these when your turbos are shot!
what u think of that?

JD was already running some high boost on his stockers way back when so its definitely doable.

Hello all.
The Stage 3's have zero problems smoking. Not one complaint yet. 17 psi, the stock turbos may last for a little while, but shaft nuts will come flying off after a little while. Might be a split second, it might be 1K miles later. The new set is bulletproof in design. High boost will not kill them. The thrust bearings are made for 180K RPM. These same turbos have seen 23-25 psi of boost on other cars. The turbine housings will max out at around 420 RWHP, but the power band is extremely impressive. The stock turbos are not reliable at higher boost levels.

Hey Matty.
JD did make power with stock twins. It took him countless hours of street tuning, dynoing, and running down the track to do it. Not to mention replacing the turbos after they went out several times in doing what he did. He tried several differnt turbos. He has spun off shaft nuts, and I think he bent a shaft one time. JD also tried an external wastegate set up which he had some luck with using with the stock twins. I give JD props. He is a person that knows what his is doing with an rx7. I talk to him via IM all the time. Good guy to know.
