I was talking with hung at miketurbo.com and he recommended the Borg s 400-sx 67mm for.my new turbo.
I had a Borg s475 standard issue turbo first.. which was super awesome. I made the mistake of trying to go ball bearing and billet wheel turbo. Got a comp ct6 triple ball bearing unit and its given me problems since day one.

I wanted a gtx4294 but now I'm thinking about this S400-sx. Hmmmm. My goal is 600-700hp and wanting decent spool plus big power. So I'm gonna maybe try this turbo and see what happens.

Any input is always appreciated. I'm sure Howard Coleman will tell me what's best. My manifold is a T6 dual gate hunk.

Badass turbo! Looking at one myself. Trying to decide if I want that or s475. Here is a link to a Honda running the 67mm.

Are you getting a refund on the comp?

So this is a different unit I am guessing? The one above(I posted)has the new one with the same comp wheel that the efr 9180 has.

Brand-new for 2012 - BorgWarner's 67mm S400SX FMW turbocharger is one of the most impressive 67mm turbos available. This unusually high power design pairs a 91mm OD FMW compressor wheel (forged billet, similar to EFR) with an ultra high flowing 83mm S400SX turbine wheel and 1.10 a/r (upgrade to 1.25 a/r available for 35+psi boost). This combination provides huge exhaust flow energy without restriction It shares identical fitments to the GT42R and S372R setups (bolt-on for a twinscroll T4 manifold and 4" downpipe).

Not quite haha its actually the cast version of the billet wheel. It moves the same amount of air (cast wheel was used for the compressor map) but weighs a few grams more. They also give the cheaper option with no race cover. $849 t6 and $1049 with a t4 footprint. The billet wheel isn't need for regular street cars from what I was told.

I'm gonna try. I asked for a refund and they sent another unit. Plus they kept my old S475 when I was told I could haveit back. Again, man its been a bad ordeal all around. Elliot at turblown probably has the power to set everything right, so maybe he will. I am really wanting my S475 back and they can have this unit back, and give me my money back minus a restocking fee.

Justin at comp turbo is a really nice guy, and is behind his product 100%. And I've tried to be a really good customer. But this is the third unit and I'm not satisfied.

Islander, i hope things work out for you re your turbo situation...

BW continues to present a fairly complicated menue of turbos... so many options.

power wise 600 hp is 80 pounds per minute and 700 is 93.

for those looking at the BW line i found a pretty good link which gives tech data and prices. i was looking to replace a damaged turbine wheel on my S300 63 (turbo PN 177283). the BW site lists distributors and i ended up at AreaDiesel.com. they happened to be nearby in Illinois, responded quickly, had the CHRA in stock (that's a new compressor wheel, bearing assembly and turbine wheel) for $433 shipped!

while i don't believe the newer EFR turbos are on the page there are lots of turbo options to consider along w price. being a BW dist these are new (genuine) BW turbos.

even if you don't buy from them there is alot of helpful BW data on the page(s).

How do you figure I have the power for that? I don't own or work at Comp Turbo. As a dealer I am just a pass through, I cannot change or bend their policies. All returns/exchanges/refunds are solely the responsibility of the manufacturer. Most retail companies operate this way, and most manufacturers request this. CompTurbo will not issues refunds after 60 days, or if a turbo has been used. Once you installed the turbo you forfeit this right, which you agreed to by purchasing the unit.

I have contacted them and was told your old turbo was shipped 3 times over the past 2 months. I have probably entertained 50 plus phone calls/emails to them. There is nothing more I can do since they are physically far away.

I would refund you any profits we gained, but I charged you exactly what CompTurbo charges;we didn't profit a dime. I also offered you a Garrett GTX at our dealer cost. There is nothing more I can do.

First of all I'm gonna let you know how I feel about the way everything was handled. When I first contacted you about the turbo issue you were supportive, asked questions, and said everything would be ok. I was happy. Well you said to ship the turbo directly to comp, which I did. After about a week or so I was calling you for updates and info. I was assuming at the time you were my go to guy. I called you every other day or waited a few days in between. Finally you told me that you were kinda busy but comp will take care of.me and I should call them.

Now if I go to Wendy's and order a hamburger and it is nasty and I take it back to the counter.... I don't expect them to say call Tyson beef cause they provided the meat. I would think that the store would handle everything in house and make sure the customer is satisfied.

I went with you cause you are well known on the forums and do quality work. I thought you were doing this servicein house. If I knew I was getting a comp turbo I would've declined. Now with that said I will admit we had a gap in communication. I contacted you and said I wanna upgrade to something "new school". Billet wheel, and ball bearing. You said cool, you would hook me up. I requested to use my custom exhaust housing and front cover if possible so I didn't have to change up any pipes or exhaust dp. I really really really thought I was getting a gtx42r. When I got the comp I was shocked. And contacted you about it. Just to say...hmmm. turbo looked cool so I said what the hell.

So now I gave you my old Borg S475 and $2000+$70 for fittings for the new turbo. It hasn't worked since day one. I started doing research about comp and found horror stories after horror stories. I was hoping for the best. I had two charlotte shops interested in these units just cause of the hype. Driven-spec, CES motorsports and oh yeah rotorsports racing. Well after all the problems I had I really just wanted to be done with comp. Their product might work great for others, but I'm plagued by them.

I'm not at all mad at you sir. And will never bad mouth you. Even Will buy from you in the future. And when I said you could possibly clear everything up this is what I'm thinking. You have a business relationship with comp, you could say hey I'm a distributor and my customer has had issues with this unit. What can we do.to resolve it. They would respect you more because of the volume of turbos you buy or possibly will buy in the future. I'm just one customer that spent x amount, your buying power is 10 fold.

I told you and Justin I was done with it cause I was tired of not getting what I asked for. But after talking to friends and shops they were telling me to get a refund. I also found out why I never got my old S475 back... Heard it was cleaned up and probably sold. :-( . I ordered a gtx4202 from CES motorsports but sold it cause I really didn't want something that big. That's why I'm trying to figure out what turbo to buy now.

How about I send you this comp turbo back, you charge me $1000 for a gtx4294 and we call it square. Or you buy me a Borg S400-sx 67mm. ;-). Lol. I feel like I got screwed bro. Stand in my shoes for a sec and please tell me what you would do. Today sir you are Neal. Elliot is now Neal for the day and will know what to do by the end of the day. Hooray Elliot, I mean Neal.

hey howard, can you please tell me which model will be the s362 in the link you provided??? sorry islander to go a lil off topic

Liborek

Well, I haven't seen S400SX-67mm offered with T6 hotside, maybe its available with some custom T6 housing but then I don't see much point in having this unit when ordinary T6 S475 flows more both on compressor and turbine side and is much cheaper. 67mm would be perfect unit for your goals if you had T4 manifold to start with.


IIRC you have GT4094R? This unit flows about 17% more on compressor side and turbine side also appears to have about 17% more area both on inducer and exducer so its safe to say that this unit should allow for at least 120 more HP. If you want bigger gains, I would move to S475 with bigger turbine (87mm).

w re to the S300 line... and just taking the info off BW's site here's how they line up:

there are 6 models but really 3... the other 3 appear to have a diff PN based on turbine A/R. i suggest using the T4 1.00 for all

so the 3 primary sizes of the S300 according to the BW site:

66 inducer

7.74 average area compressor (sq inches)
7.15 average area turbine 92% of comp

63 inducer (my turbo)

7.06 comp area
6.31 turbine area 89%

60 inducer

6.437 comp
6.31 turbine 98%

comparatively

GT 3582r

6.386 comp
5.171 turbine 81%

GT3574 (A-Spec offering)
TD60-1 (Turblown offering)

(this is a GT35 comp wheel w larger P trim hotside)

6.386 comp
5.89 turbine 92%

TO4Z, GT500R, PT6765

7.002 comp
5.89 turb 84%

one key additional diff between the S300/63 and the TO4/GT500 is the Trim of the comp wheel. the BW has a 52 trim, the others have a 63 trim

if you look at the comp maps you will see that the 63 model looks superior to the larger 66 model...

primary takeaway here is rotary friendly LARGE hotsides. maybe that's part of the reason for my stable EGT from 4200 to 8600 at 1549 F.

I am no turbo guru. Far from it... I was just looking at the max air the 4094 moves vs the new 400sx 67mm. 82lbs vs 94lbs. I am running my 4094 at 32-35psi. I need to either try and up the psi, swap to larger exhaust housing or upgrade turbo to yield more hp.

Islander

iTrader: (6)

I was told that the turbo is interchangeable. My s475 was the 83mm exhaust unit. So Hong said the 67mm would slip into my t6 .80 housing. It sounds small but Elliot said there should be no restriction up to 750-800hp. I was getting full boost between 3800-4200 depending on gear and rpm.

That new s400-sx 67mm claims 94lbs-minute, while the 74mm Borg s475 only does 98lbs-min. So in theory the smaller inducer wheel should help with spool up correct?

audoetuk

I should be happy w/ my s366

When we talked last you said spool was not a huge issue. If that is still the case I recommend using the 74mm standard cover. It will make more power, albeit a little later, and be less money. You could move up to the race cover and have an approx 75whp potential edge over the 67mm.


The cast version is very close in performance, with slightly slower spool and a minor drop in overall mass flow. However, the prices you listed are discount. The normal price (MAP) is near $1400. The price could be an indication of you running a prototype unit or someone using non-original BW parts.

The billet wheel works great for high boost efficiency, where it has an edge over the cast wheel, which is also where the race cover helps.


The turbine wheel is the same as the standard S400SX, so the housing can be swapped for an additional cost. The 67mm in a T4 housing performs quite well and in most cases that is how I would use it.


It will be a direct-fit replacement. However, for the power you are shooting for I would use at least the .90 housing, if not the 1.00. The 67m definitely has more mid-range punch when compared with the larger 70-74 compressors, and oddly enough, makes more peak power than the 71mm.

I have the s400sx FMW turbo in my posession (and for sale)... trying to pass it off on Sk8world

While its no EFR, the turbo is quite impressive!
