    I might consider a turbo timer or even this brand of coolant which David Hayes uses in his newly built Single turbo 20B rx7 and notice a significant temp drop of 11-13f

    All 9s ngk plugs
    Spark plugs were installed in January. I've done 4-5 autocross events, Deals Gap, mainly run on 93 non ethanol, use 20/50 idemitsu oil, and 1/2 oz per gallon of Idemistu premix on every fill up of 16 gallons.

    Well, the car was towed to Kilo Racing and the motor is going to be rebuilt. I won't know exactly what the cause was until he finishes up a couple jobs. So when he's cracking open the motor, I'll make sure to take pics so we all can Oooo and awe.

    So guess what?!




    It was the primary turubo oil seal that blew! Not the motor. So the motor is still pulled out of the car. Kilo says that I have a slight e shaft crank pulley wobble. Says the motor is fine for another 3-5 years. I'm sure I'll be back on this thread in 2 years saying the motor blew. We'll see.


    So I just bought stage 3 BNRs for my replacement turbos. Stock setup. Flows even better then the 99 twins and 2x as much as the oem. Runs cooler and pushes out more power.

    Not a complex setup at all

    Jokes aside, I love the engineering reasoning behind this.

    The turbos length are longer then oem. If you noticed the y-pipe is extended for this reason.

    copied:



    The new BNR Stage 3's have many improvents over the factory HT12 turbochargers. The factory HT12's are not rebuildable in most cases. The stage 3's however are not remanufactured turbochargers. They have new CHRA's (Center Housing Rotating Assemblies) and the factory end housings are machined to fit the new CHRA's. The Stage 3's are not rebuilt or remanufatured.




    The turbine wheels have larger inducer and exducer measurements over stock giving the turbine wheels more leverage to push the larger, more efficient compressor wheels while decreasing backpressure in the turbine housings. The turbine wheels have more blades giving it even more leverage than before and also the wheel casting is much thicker than stock. In an event of a blown apex seal, the turbine wheel (more than likely) will survive, unlike the stock turbine wheels in the stock twins or the 99 spec twins which are a very thin cast that will be heavily damaged. Apex seal damage will cause slow spool, inadequate boost, and lack of power. The shafts in the stage 3's are 1/4" in diameter compared to 5mm in diameter like the stock/99 spec twins. Also the shaft has left hand thread shaft nuts which eliminates the issues of shaft nuts shooting off like the stock turbos have a tendancy to do under high boost. It can lead to engine failure if cases are bad enough.

    The thrust bearings are upgraded to a 360 degrees for proper lubrication of the rotating assemblies up to 180K rpm! This means you can run a tremendous amount of boost without killing thrust bearings. The stock thrust bearings are 270 degree bearings which aren't reliable to run over 15 psi of boost. 360 bearings are standard on BNR Stage 3's.

    The stage 3 comes with an adjustable wastegate actuator. This allows you to turn up or down the boost mechanically w/o a electronic or manual boost controller. The adjustable actuator can also make the boost controllers more effective because you are working them less to turn up the boost.

    sequential or non? either way, great choice!

    Don't think I saw this in your thread, but since cooling is a big concern with these, are you still on the stock downpipe?

    Still sequential. I believe that it's pointless to go non sequential on twins like some owners do. If that's the case, just install a single turbo and be done with it. I couldn't tell you how many people give me crap about why I should've gone single but they all also know why I chose to stick with the twins. It's a love hate.
    I integrated a product for my cooling system called Engine Ice. David Hayes has real world results of 7-8 degrees cooler temps in his single turbo 20 B that Kilo Racing witness as he performed the engine install of his car. This is after the fact that kilo did the V-mount install for his 20B!

    Mid-summer!


    I also have a Hks downpipe wrapped in PTP lava wrap.

    Still need an intercooler, tune, and maybe a mid-pipe. I'm pumped with the numbers...

    Ok. With that I had a 'moment'. What are these #s you speak of. I saw no numbers. We want to know.
