Based on your thread it appears that u havent tried any
Looking for someone who did so he can provide logs and data.
A week ago u were still trying to find a source for purchasing one so I don't think ur comment has any backed up information

Costas, the corrected mass flow is so similar it's not funny. The big difference is the turbine wheel's. The 363 is 76mm over 68mm. The 366 is 80 over 73.
To make a decision I wouldn't be really comparing the compressor wheels here. Many people fail to look at the "exhaust side" of the turbocharged engine to really make their setups fit as far as efficiency or power. PM me or call me if you want...

I know exactly what you are saying. I fell in that trap with my GTX4294R. I definately dont want the same things to repeat
somehow BW claims that they both have the same flow just at different pressures. true or not who am i to judge.
hence the question of DIRECT EXPERIENCE.
I know you worked on the BW turbos quite a bit. Unlike some other computer based engine builders/performance experts that learn from youtube videos

I think what he's saying is although you are just sharing it has no relevance to our cars/ engines. A my 35r with t4 hot side and wheel spooled real quick on my 12a... But would more likely than not be laggy on your car. I'm not trying to insult anyone.. Just saying

I've only had a 366 on a rx7 but have used both in multiple diesel builds. Honestly the smaller ones are not worth messing around with since the 366 is generally cheaper and boost threshold is damn near the same from a 360 to a 366. If you want response make sure you have no exhaust or boost leaks and run a tighter a/r. It may limit your power up top but will come in faster on the low end. Then again everyone idea of lag is different.

I cant say that your comment is helpful in sort of way. With any setups you obviously don't want boost or exhaust leaks .... how does that help someone understand whether this setup is suitable for someone's application. ?????
So in other words let me get a GT55 or larger but as long as i dont have any boost leaks i am ok ?!?! everything that you said above is, to say the least, IRRELEVANT !

while this is a 5 year old thread i suppose the setup is still "valid". it is from this century anyway

i found this that says:
................................................. ..S366..........................................S3 63
14.7 PSI Boost...............66 pounds 497 rwhp....................64 pounds 482 rwhp
20 psi............................72.4 pounds 545 rwhp.................70.6 pounds 532 rwhp
max air at 62% eff.........76 pounds 573 rwhp...................76 pounds 573 rwhp
you may be thinking that the S366 has an edge so what is this thread about. i say that the hp diff between the two turbos is a jump ball.
what isn't a jump ball is that the S366 compressor wheel is 10% larger.
S366 compressor area is 7.743 square inches
S363 compressor area is 7.04 sq inches.
this isn't "jump ball." this is a major spool drag for the S366. a drag you feel all the time.
in addition, the heaviest part of the turbo by miles is the turbine wheel assembly. the S366 has a 7.151 sq inch turbine while the S363 has a 6.31 sq inch wheel. the S363 is much lighter which also promotes spool.
granted the rotary likes a larger hotside but the 6.31 S363 is plenty large...
compare it to the typical "big" Garrett P trim wheel at 5.89 sq inches.
so you have to swing a 10% larger compressor wheel and a 13% larger hotside w the S366 and just what do you get out of it V the S363?
both turbos are the same 9.19 inches in length and all other outer dimensions.
perhaps one of the reasons many end up w the S366 is that there is more of a settlement as to the name.... "S366"
just try to figure out what you are looking for w the S363 (my tag BTW)
it could be:
S300SX3- 63
BW S300SX8875
S362
i could go on.
what you want is a BW 177283 with a 177209 hotside (T4 divided 1.00 A/R)
the 177209 does not come w the turbo and is extra, around $170. Full-Race does sell the 177283 w the 177209 for the same price.
as always, shopping around pays dividends.
another nice option is a conversion of the weird 4.21 inch back end V band to a more friendly 3 inch. this is available from some vendors for $150 or so.
given the pricing, quality and configuration, this turbo is a great value for the FD owner looking to make around 500 at 20 or so psi.
as to mid-range... i run 295 rear tires at 27 psi and rolling into boost in 3rd i am on the edge of adhesion at 46% throttle at 14 psi. you will be happy w the midrange
favoring midrange on both turbos is a 52 trim on the compressor wheels. this compares to 63 trim on the Garrett/PT wheel of similar dimension to the 363. in spite of the 52 trim i found the 363 still delivering a lot of power at 8650 rpm...

EFR 9180?
my cousin was going to run it on his supra and he was saying to get one but i was looking at spool and all was comparing it and then was going to compare to the 369
after sevenstock i confirmed the EFR 9180 best out of everything
this just sucks me in to get it definately...what pump and what are your power goals
