Yes, with pump E85.
No on pump 91 octane.
Both are pump fuel, not race gas.
95 Supra TT (Hybrid GT28R's), Alpine Silver, ProEfi, ATF built A340 Auto
93 Supra NA, Baltic Blue
Hey Brian, how do you like the hybrids with the auto? Sequential or TTC?
93 Alpine Silver TT Auto BPU: HKS Super Dragger, Random Tech hi flow cat, IK22 .032", K&N filter, Synapse DV diverter valve, MVP bcc, ebv spring mod x2 @ 13 psi, wg spring mod x3, innovate SCG-1 ~17 psi, emanage blue
Cooling: AIS W/M injection 12GPH, SM auto trans cooler external filter, CSF rad
Suspension and Handling: TRD front strut bar, bilstein shock/oem spring combo
I am running sequential. I like that I can cruise around with plenty of low end response from the first turbo, but when the second turbo comes on it hits like a bat outa hell. Haven't tried TTC mode but personally, if I were gonna go TTC, might as well just go single.
Regarding the hybrids with the auto, I love it. With the new torque converters out now, you can dial it in however you like, for drag or street. I switched to the 4k stall for drag and love the speed and launch, and can always go back to a lower stall if you are going to be doing more roll racing or just street driving.

Thanks for the feedback, looks like you are at a different level here with the e85 extra volume for spoiling up the turbos, 4K stall and all. What's the lowest stall you have driven in with the set up and used non ethanol pump? Just wondering how they would perform given the worst case scenario of stock stall, 91 octane, piggyback on stock Ecu.
I would occasionally smoke a Camaro or WRX with these turbos and the stock stall! As you know people always wanna race when you are in a Supra! 😉
I remember one Camaro that got a good jump on me, and he was rowing gears as I proceeded to reel him in and pass by him! That is the benefit of the auto tranny being quicker. He looked pretty pissed ha ha! But I remember thinking how I could not have done that with the stock turbos. So if the GT28R turbo upgrade with the auto tranny on 91 octane, is good enough to smoke a 430+ hp V8... then I would say it performs pretty damn good imo. Try doing that with the stock turbos...

Looking good Eric. What wheel did you go for in the end?
Did Albert any potential problems with using GTX wheels in a non-ported shroud?
Can you confirm that the stock Artec pipe uses the same sized inlets as the OEM pipe and that the only difference is the outlet at 80mm.

Everything is bigger on the Artec, I don't think it's 80mm through 76mm maybe i think that's 3" GTX wheels in non ported shroud? Not sure what you are talking about.
@STU btw, i measured both JDM twins are the same size, I think where ever that info was given was wrong. I have 3 sets and Albert M agrees as he has rebuilt countless and they all have the same sized compressor.
Screen Shot 2019-04-12 at 15.09.59.png I believe it is for anti surge. As the OEM housings aren't like this I wondered if there would be any negative effects on performance or if Albert mentioned anything to you?
When I looking into this I spoke with a Garrett rep regarding shoe horning any of their GTX wheels into the OEM housing and they advised me against doing it as they said their wheels were designed to run in ported housing.

You only need anti surge if you were surging in the first place. I doubts turbos this small will make a 3.0 surge no matter what you do. So I’d say you could ignore garret on that. Besides GTX wheels have been done already.
I wanted GTX, but Albert didn't have them. So i ended up with GT. I don't expect record-breaking numbers. I have 47.1 / 60.1 which would be the same as GT28 or GTX28 only difference is GTX has 11 blade GT has 6+6. BNR upgrdes use 16G wheels which allow for high boost pressures which is good since there is so much back pressure in the system due to the small piping. So if you think of talons doing 30-40 PSI of boost it makes sense why BNR chose these wheels. GTX wheels have higher PR ratios according to the maps as well. I suspect I will run out of steam around the 580-620 HP mark on E85. Which is fine with me for now since the mk3 will need some love to hold more torque with the R154 and the fact that I am using a stock fuel line with 1300CC injectors and 1 walbro 485.
Artec is 80mm and 57.6 on both collectors
I'm going to go for the GT28 turbine wheels on mine also.
Do I need to tell my engineering shop to increase the compressor wheel size, or is it simply a case of having them out of steel in the original size?
Anything else I need to specify out of the norm for them to do also?
1993 TT6 - stock...for now...
Stu should be able to answer your technical question regarding the compressor wheel size.
If you order from BNR or from Stu Hagen there are instructions and a full installation kit that they can send you for the installation.

Stu, any updates on the manifolds?
