That is why I bought it this early, to get a gauge of it's size and start playing with where to mount it. Currently it is between fog light mounting and finding a way to squeeze it in rotated. Fog light seems to be the more likely approach.

I don't really have an exact whp target, but enough to scare some of the serious cars at RSDs. RSDs stands for Real Street Drags, basically street racing, but at a drag strip so none of the legal issues. But you can give spots, go off a light or whatever instead of a tree, betting is encouraged... etc.

Rex,
Why no anti-surge housing?

Hi Walter,

It actually is an anti surge housing. Borg does it a bit differently than other people, this is a quick picture off google to illustrate.


You can see the slot at the top of the compressor blades and a large slot further up the inlet. The surge port is actually set up so when you look straight at the turbo it isn't apparent it has one, but the ports are integrated into the walls of the inlet so it indeed is an anti-surge housing.

Hi guys, my name's Manny and I'm relatively new to Borg Warners.

I was looking at the S256 I believe, but currently am running a single scroll setup. I hope to go twin scroll some time in the future, but for now, it seems unlikely. Can I run the divided Borg Warner turbo without any damage / only the loss of the benefit of being twin scroll without issue for the moment? My ideal turbo would be a Air Werks line that is T4 single scroll, with a 3in Vband down pipe making about 500whp.

http://www.agpturbo.com/borg-warner-...-580-hp-turbo/

This is the turbo I was looking into. To give you an idea of the setup I am currently running:



I ended up getting this turbo for a steal, and was mislead to what it truly was. It is laggy as all hell. Turns out it's an old Precision turbo that was originally for diesel performance. Needless to say that I am unhappy with it. I would also prefer something from the Airwerks line too. If anyone could help lead me in the right direction, it would be greatly appreciated.

Motor specs:

Engine / Drivetrain:
Beatrush Alternator Cover
Beatrush Air / Oil Seperator / Catch Can
Borla Unequal Length Headers
Pfitzner Performance Gearbox (PPG) Helical cut 1-5/R Dogbox (Built by Andrewtech Automotive)
Beatrush Forged Motor Mounts
Beatrush Transmission mount
Beatrush Forged Pitchstop
Deatschwerk Topfeed 850CC Injectors
Cusco Tarmac Center Differential
ARC Radiator Cap
HKS Carbon Ti Catback Exhaust
Precision GT-Q 70 trim T-4 w/ anti-surge housing
Tune by Michael Adkins
HKS Camp-2 (w/ supporting sensors)
Tial 44mm External Wastegate
Aeromotive 300lph fuel pump
TurboXS FMIC
ACT 6 Puck Sprung Clutch
Optima Yellow Top Battery (Relocated to Trunk)
Performance Race Solutions Rotated Mount Turbo kit & FMIC piping
Perrin Top Feed Fuel Rail kit
Cosworth Main Bearings
Cosworth 11mm Headstuds
Cosworth Rod Bearings
Cosworth High Volume Intake Manifold
Cosworth High Volume/High pressure Blueprinted Oil Pump
CP Pistons / Rings 100mm 9:1 Compression
ARP Case Studs
Power Enterprises Timing Belt
Mishimoto Radiator
Mishimoto Radiator Hose kit
Brian Crower Stage 2 - 272 spec Camshafts
Brian Crower Titanium spring / retainer kit
Brian Crower Intake Valves 37mm
Brian Crower Exhaust Valves 33mm
Ported & Polished head

...and if anyone could recommend a non-laggy Airwerks line, that would be amazing.

Thank you guys in advance,
Manny

The S200SX turbos are now available with T3 external WG housings - that should work well for you and you could easily swap to the twinscroll housing at a later date when you are ready to change the exhaust manifold and up pipe

At least you won't have pressure (much) to keep the oil in the return line.



That would be the real option. If it were me, I'd add three stages and get both heads into that system
How would you go about doing that?

So I'm excited to say I saw the full race kit pricing has come down a LOT. And my dream of getting one is a lot closer. Ordering it ewgless and I'm going to have custom side exit ewg's made.


Anyway



I'm looking at a s200 7670 but in t4 twin scroll, don't need more than 400whp @20psi on pump gas 93 octane. Want good spool and power to redline.

Might get a bullseye batmowheel billet compressor wheel if they make one for the s200 turbos.


I don't get how/why these journal bearing turbos spool so fast compared to a Bb turbo of the same size. How's transient response compared to a bb turbo of the same size?


To say the least I'm going to be excited when it happens.

It was made by homemade wrx I think

that is an excellent turbo, one of the best values in the industry and with twinscroll configuration it works GREAT and can definitely meet your targets.

It comes down to borg warner's unique turbine wheels, which have excellent turbine efficiency .. everyone seems to get caught up starting at shiny billet compressor wheels, but the turbine wheel and housing is IMHO the most critical and overlooked element in any turbo

i do not recommend that... the testing ive seen indicates the batmowheel is a gimmick that does not perform

Done, 7670 it is. and ill tell you guys about my side exit idea when I call to order. Hopefully over summer. Basically I want 2 38mm ewg's welded on the manifold or up pipe near the mani to up pipe connection and they will go out the bottom passenger side of the front bumper by the wheel well.

Wat hot side do you recommend? Stock 2.5 block and heads.


Eventually will have a de stroked 2.3 sleeved and bored back to 2.5. But I will probably will have a bigger turbo then anyway.

Interesting! Can the S200SX 7670 come with a divided T3 housing (w/ V-band outlet)?

Aslo the S200SX 7670, does it use the same turbine and compressor wheels as the EFR 7670 turbo?

Thanks, Geoff!

Nope.

It's not a billet compressor wheel.



Also how durable are they to abuse, high temps and rally style antilag?

I have the s200sx 8070 its a great turbo. On a mustang dyno it made 400 whp @ 20 psi on 92 pump gas. Feels good on the street. Running full-race el headers and downpipe.

I switched eventually to that turbo (S200SX 7670) and also had a DOM3 (3076R) before on the exact same engine. My DOM3 had the 8cm² A/R turbine housing. So, same size compressor wheel, only different hot sides.

The 7670 I ordered had a sort of hybrid T3 twin scroll with T4 bolt pattern and flange and ported to fit a T4 tiwn-scroll flange.

The 7670 spooled only 200-300 rpm later BUT made the same torque (and this hp) down low!
Conclusion: the larger, but also better flowing twin-scroll turbine housing caused a better VE of the engine, thus using the available boost better through less back-pressure.
Up top the 7670 made 50 hp more (maybe also because 4" intake BW vs 2,4" intake DOM3)

YMMV

How much bigger was the hot side on the 7670?


That's still pretty damn good if u ask me. I will be getting it in ts aswell.


I want the hot side to be big enough to hold power just to redline without falling off, but not be laggy as piss.

the 8070 is another excellent turbo in the lineup, here is a dyno comparison on a stock internal 2.5L STI of the S200SX 80-70 (green) VS the S300sx 8375 (red) with our FR twinscroll kit:

that is consistent with what we've seen, thanks for posting. One thing to note is that the 70mm turbine wheel is a *really* good wheel... extremely efficient and i believe is mostly responsible for the gains compared to your old garrett - not just the twinscroll turbine housing

-the S200SX 7670 has the same turbine wheel blade shape as the EFR, but it does not share the superback on the turbine wheel nor does it have the same compressor
-S200SX are not available with any sort of T3 housing, T4 only, however there are T3 sized openings on the T4 bolt pattern... so you could definitely make it work with a T3 if you wanted.

would you mind posting your dyno chart? Interested to see if possible
