Is a bw s366 good choice for only looking to make 400-450 rwhp?

YOU can get the s300SXE or "s362" as the fanboys renamed them.. for $640+150 for the turbine housing. the old s300 turbos go for about that or a 100 less.
they're all called s300 sxe. the 62mm is the smallest. I call it the 8374... because i read it uses the same wheel as the EFR 8374, it just loses the *****, the IWG, and the built in diverter valve..and the TI gamme turbine material. correct me if im wrong.
what i am getting is is the S300SXE series is the NEW s300 series of cheap but awesome turbos and you should defiantly be replacing old blown out s300sx3 and older turbos with these new units.

but as far as I know both the "BW S300SX 8875 Turbo S362" that I have; and the "BW S300SXE 8374 turbo S362" with the EFR wheel have the same flower rate of 75lb/min. or does that not matter??

your talking about the FMW right?? could you please provide the link as to where you found these amazing prices; because if that's the case, then i might as well just get the super core when the time comes, I already have BW .91 A/R with the 3" V band welded nicely thanks to John at GLEASEMAN.

thmotorsports,$580 refuned my money twice with no email or phone call why.. maybe you'll have better luck... this was me trying to get the 7670 s200SXE..
https://thmotorsports.com/borgwarner...i-2283236.aspx
jegs..$710
called them july said it would be aug, called them aug told me it would be sep, i told them cancel....
13009097056 | JEGS High Performance
then i put my part number in ebay search about every 2 or 3 days waiting for one to pop up, and it did.. sooner then if i had waited for jegs... i then had to turn around and do the same for my turbine housing.. which took another week for one to pop up...
the number you want is 13009097056.
and there are 4 on ebay right now, one at $710.. Real Borg Warner S300SX E 61mm Turbo 13009097056 Fastest Shipping on eBay | eBay
may the odds be ever in yalls favor.

Bump for old thread but still want to make this clear for what I'm seeing here. So the BW s366 divided T4 .91A/R will go 450+ whp on pump fuel only? No need water meth or e85? Or a must to go whichever? Someone explain . Are we talking about a certain type of dyno or what's up

It can depending on setup and tune. Personally I don't recommend it for a sub 500hp goal because it isn't exactly the quickest spooling turbo. I'd rather trade a few peak ponies and have better midrange and response. The turbo is also quite dated. If you want something newer without breaking the bank go with one of the SXE offerings.

while there is some good info in this thread there sure is a lot of confusion too so let me set the record straight....
Borg Warner has offered the S300 series for many years...
inexpensive and with a 23% larger rotary friendly turbine wheel V the GT35.
technology marched ahead and the S300 was joined by the clean sheet of paper EFR series
after the inevitable speed bumps were ironed out (about a year and a half to fix the titanium/aluminide turbine wheel separating from the shaft) the EFR showed it's stuff.
BW then laid another offering on the table which was a significantly re-engineered S300 line tagged the S300 SXE.
while the EFR line is generally priced over $2000 the SXE line is often sub $1000.
do not discount the SXE as it offers top shelf engineering.
BW is a 9 Billion $ revenue company and they engineer things only one way. OE.
for instance the bearing system on all SXEs is all new featuring among other things a 360 thrust bearing.
the SXE line uses a newly designed billet compressor wheel somewhat similar (but a later design) to the EFR.
there was talk about billet being just about the same as cast. i remember reading a comparative piece on the Garrett website back when they didn't offer billets... saying no big deal. of course they were busy playing catch up at the time.
billet wheels are stronger than cast. at max boost generally the air coming out of the turbo is close to 350 F accompanied by lots of pressure and 100,000 RPM. almost all materials are plastic when faced with pressure and heat... it is only a question of degree.
billet will deform less than cast.
don't think billet is an advantage? take a close comparative look at two compressor wheels of the same outer dimensions... the cast wheel will have a larger nose. noses don't flow air unless they are on your face. the billet compressor wheel nose will be smaller so there will be more working blade area per diameter.
advantage billet.
recent advances in aero-efficiency are major and are most recently expressed in the SXE wheels.
the S300 SXE comp wheel is close to the EFR 8374 wheel... (SXE 62 is 6.54 sq inch average area V 6.626 for the EFR 8374) however the SXE was designed almost 5 years later.
in addition, BW delayed the rollout of the SXE line 6 months because they made a breakthrough in the COVER design. all SXE turbos utilize this new cover.
the payoff:
the left boundry of the compressor map is a key indication of compressor efficiency. how early does it start to work. here, lower numbers are better.
at two pressure ratios (14.7 psi boost) the SXE starts working at 16.5 pounds of air per minute while the EFR 8374 surges until 20 pounds per minute
at 2.4 pressure ratios (20.58 psi) the SXE starts working at 23 pounds per minute while the EFR starts at 26.
at 3 pressure ratios (29.4 psi) the numbers again favor the SXE 30 and 34.
advantage SXE.
this improved efficiency of course is also expressed at the other end of the compressor map which is where the power resides...
the small numbers on a compressor map matter as they measure heat. heat is bad as you are after density in charge air. hotter volumes of air possess less oxygen molecules as they are busy vibrating against each other and therefore taking up more room. colder air wins because it has more oxygen to burn inside the motor.
looking at the 70% efficiency islands of the SXE and EFR turbos we see wider islands on the SXE maps. wider is better.
at 70% efficiency
at 2 pressure ratios (14.7 psi boost) the SXE delivery extends to 57.5 pounds of air per minute while the EFR is at 53.5.
at 2.4 pressure ratios (20.5 psi) the SXE makes 65 versus the EFR at 62.5
at 3 (29.4 psi) pressure ratios the numbers are 70.5 V 67.5
advantage SXE.
i am not knocking the EFR line as they are excellent and i personally own an EFR9180. i am just pointing out that the SXE line presents a genuine high tech lower cost option.
as to which of the 5 SXEs you should consider:
SXE "62" (actually 61.44) max rotary rwhp 573
SXE "63" max rrwhp 584 rrwhp
SXE "64" (64.5) 618rrwhp
SXE "66" 648 rrwhp
SXE 69 738 rrwhp
all SXE turbos are interchangeable! neat.
you do have 2 options as to turbine size.... 76 and 80.
as to the initial poster looking for 450 or so, of course the 62 would be the turbo...
i have my favorites amongst the 5 and will be posting some data.
me being the financial analyst that i was prior to retirement i did a fun excercise where i took max rotary rwhp at 3 pressure ratios and the typical price of the turbo and came up w this...
GT4094r $2.58 per pony
EFR 9180 $3.16
SXE 69 1.11
SXE 66 1.17
GTX3584RS 3.53
all good turbos, all good options. BTW, i sell them (Garrett, BW SXE and EFR) and am always happy to consult

Read through your post, well said 
Take a peak at the line I bolded down below, double check those numbers as they're the same as 1 PR and I'm pretty confident they're in error
