Borg Warner Turbos
 

Just thought I'd start this up with what I've found on these turbos so far. It's a bit difficult to find info on these compared to all the info out there for Garretts and what not. So if anyone has any good info on these, post it up!

Basically for those of you who don't know anything about these, they use something called Extended Tip Technology on some their compressor wheels (they also offer non-ET compressors as well) to help them flow more air at the same levels as a typical compressor wheel of the same size would flow. They also supposidely try to reduce the rotating mass to help spool. So in the end, the advantage is supposed to be it can flow more air then say a compressor wheel of the same size from Garrett which doesn't utilize ETT. I am not for sure, but I believe Brent Rau runs one of these turbo's, as well as MAP's FD. SLS has also done some testing with these turbos with great results.

I personally am going to be running a used S362 I picked up. These things come in both extended and non-extended tip forms. I wasn't 100% sure when I bought this, if I had gotten an ET or non-ET version, but it was a good deal so I grabbed it anyway. Everyone was beating around the bush when I asked exactly what tip on the compressor was extended, and extended in what way. Every responce I've ever gotten was either a "well i think..." or a "the tips are extended on the compressor wheel, duh". Well that sure doesn't clarify anything. I finally found out that it's the tips on the exducer, are extended out over the center cartridge. There's a good picture of this in a later post.

Also, these turbos typically run 14 (7 tall, 7 short) fins on the compressor wheel instead of 12

So anywho, I'll be running one of these next year and I guess we'll see how it performs for me. I'll be mating it up more then likely to a bullseye .70a/r T3 v-band exhaust housing, and bolting it up to my SLS T3 manifold.

Here's a few other pics I found that are also interesting:

Re: Borg Warner Turbos
 

Rau and Kiggly both run BorgWarner turbos.

Re: Borg Warner Turbos
 

I would too if i was given free turbos!

Re: Borg Warner Turbos
 

So, any idea when this turbo is going on? I have been eyeing up the borg warners too and am also not finding a ton of info. Most of the responses have been good though. I was looking at the S366 or S364. It wouldn't be until next spring, but I always over research everything :D

Re: Borg Warner Turbos
 

Ask BW about the S380 :wink:

Re: Borg Warner Turbos
 

I don't want to go that big. I am pretty happy with the scm61, but I will probably go a bit bigger when I max that out. I know the exhaust side is WAY too small for my setup. 75 lb/min is about what I would be looking for.

Re: Borg Warner Turbos
 

The T67 dbb/t-3 .82/p-trim is what you want. :cheer:

Re: Borg Warner Turbos
 

The 4088R/4094R is the other turbo I am looking at.

Re: Borg Warner Turbos
 

JET, don't go that big, it'l spoil the fun of the car! If you want to go bigger, go for a BB T67!

Re: Borg Warner Turbos
 

Yeah, what he said!!! :nod:

Re: Borg Warner Turbos
 

BBT67 and 4088R are almost the same size, the 4088 is just the newer GT style. The 4088R is a 70lb/min turbo so it isn't much bigger than the SCM61, except the exhaust side will be much better. The T67 is actually 75 lb/min.

Re: Borg Warner Turbos
 

The GT4088 has a 64.5mm(I think) compressor wheel. It's a newer wheel than the commonly used TO4R 67mm wheel, and there has some debate on which wheel is actually better. They seem to capable of similar power. We run non-DBB GT4088s on Kenny's Mustang. They were quite inexpensive back when we bought them, but have gone up in price. The GT4094 also has a 67mm compressor wheel, it's a little bigger than the usual 67mm wheel.

Re: Borg Warner Turbos
 

What do you think is the best turbo around that flow, Shane? I will be making my own piping/manifold, so I can put about anything in. From what I have seen the BBT67 and 4088R are about the same too, with slightly better spool on the 4088R. Info on the S364 is pretty limited from what I can find.

Re: Borg Warner Turbos
 

Well I want to get this turbo on this winter, but the 50trim may go one more season. I've been slowly aquiring my parts. But there are some big things I still need. I need to completely rethink my fuel pump situation, I still need a new Tranny, then I need a clutch that will support the power I'll make. I'm still waiting on my turbo to be sent to BE for them to put a new exhaust housing on it, because they want to verify my exhaust wheel size. So I have a lot of money I need to drop yet, and so this may not happen until next winter. But we'll see. It's been awhile since I found the compressor map, but I thought the 362 put out mid 60 lb/min of flow. That's plenty for my blood. Plus they are supposed to spool pretty well. But ya you are right, it's hard to find info on them.

Re: Borg Warner Turbos
 

Alright, I hear where you are coming from Brandon. I was just hoping it would be sooner so I could talk to someone that was running one :D

Re: Borg Warner Turbos
 

cough, cough,.....T67....., cough, cough

Re: Borg Warner Turbos
 

Talk to MAP ;) But their's is kinda bigger then you're wanting to go I'm guessing :D

Re: Borg Warner Turbos
 

So I ordered a new S362 up like I said in my project post. But I just wanted to clear up some mis-information that I had receieved, and shared in my first post. The "extended tip" on these turbo's is on the exducer. The tips extend over the backplate like seen in this picture. Not how tall they are, and it has nothing to do with being able to see the smaller blades from the inlet. That other turbo I had ended up being a Non-ET version.

Re: Borg Warner Turbos
 

Good info, thanks.

Re: Borg Warner Turbos
 

Just some more info I just got. If you've heard that these turbos use some kind of British Pipe Thread or something for the oil fittings, that is only true for the S200's. The S300's use 1/4 NPT.

Re: Borg Warner Turbos
 

who did you get your turbo through?

Re: Borg Warner Turbos
 

You can get them through a ton of different vendors. MAP should be able to get them fairly easily.

Re: Borg Warner Turbos
 

SO i was just looking at random stuff and i think i read this right, but turbonetics sells a "K" version of their turbos that have an extended tip.

Re: Borg Warner Turbos
 

I'm gonna try one of these this year(not on the dsm), so I'll report back what I think of it.

Re: Borg Warner Turbos
 

Word. The T88H-38GK

Re: Borg Warner Turbos
 

I think it was listed as GT-K series 66mm turbo blah blah blah.

Re: Borg Warner Turbos
 

Which one you looking at?

Re: Borg Warner Turbos
 

Something in the S400 range. Going pretty big, but have to pick all the specs still.

Just thought I'd share some recent results. These were both T3 housed S256's. One in a small .55A/R and one in the same .7 A/R housing I'm running.

Re: Borg Warner Turbos
 

Yeah i saw that shit last night, its fucking sweet.
This will be my next turbo for sure, but i guess i should actually get started with this one.

Re: Borg Warner Turbos
 

This might be my next turbo in a short time.
Some interesting info

Re: Borg Warner Turbos
 

I'm gonna bump this thread from the dead. Obviously halon is using a BW turbo, anyone else using one? I'd like to see some real numbers for a dsm, spent a little while digging through dsmtuners, and eventually got a headache and gave up. I myself am looking at an extended tip s256 or s259.

Re: Borg Warner Turbos
 

S259, i think replaced teh S258, also go bigger if not you won't be cool and we won't remember you or your car. lol

Re: Borg Warner Turbos
 

I could care less about being remembered haha. I just want a good street/strip/track turbo, and like the spool characteristics Ive been reading about when it comes to their turbos.

Re: Borg Warner Turbos
 

I'd say MAP is having decent success with the one they have in their FDSM, hahaa.

I'd also recommend considering the 259. I like my 362, but a hair less lag wouldn't hurt, and it should still be capable of some damn good numbers.

Re: Borg Warner Turbos
 

What do you see full boost at on your 362? I still have some reading to do, there's a lot of info on the s256.

Re: Borg Warner Turbos
 

I can't remember exactly off the top of my head, but I feel like I was seeing 30psi just after 5k I think.

Re: Borg Warner Turbos
 

I'm just being stupid.
If what u say is true about street/strip, then you will want to stay between teh S256 or 259.

Re: Borg Warner Turbos
 

BTW, who are you?

Re: Borg Warner Turbos
 

I caught your e-sarcasm lol. And yea, 50trim sized turbos are what I have been looking at lately. I got rid of an scm6152e, cause I just didnt want anything that big, or with that much lag. I'll have to keep reading up I guess.
