So im thinking about a BNR stage two turbo. Someone also just recomended I look into the the Gt3071 from garrett. I was considering the the gt28rs but i was told that the torbo wont match the turbo manifold on the s5ts. Im trying to get to about 300 to 350 (if that) maxhp with fast spool. Ill be on a large street port too. Has anyone settled into these numbers? I know its not a huge number like 400+. what turbo did you use?

For the money, BNR Stage 2 would be recommended, along with 4 x 750cc injectors, RTek 1.8 or 2.0 (For ability to tune), 255 LPH fuel pump, TID mod, 3" turbo-back exhaust system. You should have enough fuel for 312rwhp at max 85% duty cycle.
I have a BNR Stage 4 and the above modifications, but chose it for future target level of 375 - 400 rwhp once I add Megasquirt ECU, 2 x 1600cc secondary injectors, and alcohol injection.

what are you doing for fuel manage? Sorry whats a TID mod? As far as turbo backs go I think i would go with racing beat. they are athe only ones i have found that are 3" all the way to y pipe inlet. I want to keep the dual look. I have a supra tt pump already.

There are many options for a 3 inch turbo back. Corksport makes one for really cheap, although it is a MUCH different style than Racing Beat's.
ya the 2.0 is the one you can mess with. the 1.xs are preset maps i believe. I was thinking about the 1.7 with a piggy system. afc or fcon. not sure yet. Im doing all kinds of homework right now on when to put the bigger injectors in and put more fuel in. i dont want to run lean and blow up during break-in on a large street port. that would suck major nads.

The stage 2 seems to be exactly what youre looking for, I have similar power goals, but will probably go w/ a 3 or 4 as long as it will spool quick.
The gt 30 would be great, they spool quick on an fd (never seen one on an fc). But the question is, how much is a little farr spool worth to you? By the time u buy the turbo , manifold and watergate, you could easily spend double what the bnr would cost , and u still need an ecu and tune .
As for the exhaust, the RB rev t2 is the second nicest dual setup out there, but its the best currently in production. I found the rb catback and downpipe for cheap and had an exhaust shop make me a mid pipe w/ a borla xr-1, came out to about half of what the system costs new.

Racing Beat Rev TII system is hard to beat in quality, and comfort.
Dual canister style exhaust is just plain too loud for me. RB Rev TII is just the right amount of noise where it is nice and deep, yet wont make your ears bleed on the highway from the drone.
Only bad thing about it is that it is more heavy then other duals. The materials its made out of is thicker then other exhaust systems, a plus to thicker materials is more sound damping.
Though they are pretty pricey, but for me its pretty much worth it just for the sound quality, they also flow as much as a canister exhaust from what Ive heard

the 3071 and the BNR stage 2 is basically same size compressor wise on the exducer, but the 3071 inducer is smaller then a H3 wheel which BNR uses in their stage 2. From looking at the compressor maps of both wheel, the 3071 needs more PSI to be efficient where the H3 wheel is suitable at a lower PSI and has just about the same efficiency as the 3071. Basically, the BNR stage 2 will make the same amount of power as the 3071 at a lower boost because of its bigger wheel.
You might as well get the Stage 3 BNR. The 60-1 wheel is bigger and is more suited for a rotary engine money wise. Plus, all BNR turbos are practically bolt ons, whereas with the 3071R you will need to get an aftermarket exhaust manifold.
Somebody can correct me if I am wrong
