Mmmm I wonder what they're upgrading.......

Let's hope they are making a Bigger EFR turbo. Have a few 20bs that are in need of some EFR love and some BIG 13B's that want some action to.

Full-Race Geoff

bigger EFR will not happen, we simply are not able to make gamma-ti turbine wheels larger than 80mm at this time.

The legit solution to these big power 20b/13b is twin EFR's. Ive used these turbos on a lot of engines, and without any question twin EFRs really, really work well..

Damn. Twin's is just difficult on these old school mazdas. lol

Oh well.
Maybe three 8374 on a 20b would be a good drag setup.

Too big. If you are doing one turbo per rotor you'd be better off with a 7670 or smaller.

rx72c

iTrader: (8)

Disagree. Have setup 20b with 3 GT35Rs and it was a little on the small side for a drag setup.
Only one way to find out.

I personally do not like mutliple turbo setups with single throttle bodies..

For drag, maybe. That's i world a stay out of

Hey Elliot

Have you had issues with this type of setup?

Full-Race Geoff

I'd suggest triple EFR7163

what was the power target, and what did that car end up making? That sounds crazy

what is your reason for this? I have had very good results with twin turbos over the last few years. I used to consider myself a single turbo guy, but now prefer twins to singles..

Twins work great on V configuration engines, but not on an engine where you cannot plumb the intake and exhaust perfectly symmetrical. In drag racing its fine where you do not put much mileage on the systems..

I know this post might kind sort of pointless, but I spoke with BorgWarner about the SX-E lineup yesterday. While I cannot reveal what was said as they don't want it to be public( I assume because of the market's competitiveness), I am impressed with the level of performance engineering that has gone into these turbos. BorgWarner is really paying a lot of attention to all the details, and really testing all aspects to gain the maximum in performance. We are going to do a back to back test vs a standard airwerks when the SX-E becomes available.

Rotate86

Awesome to hear!
Have heard a couple of different versions of the reasons for a delay but regardless i will have a 64mm as soon as available.
look forward to the direct comparisons.also am interested where they will fit in price wise

Definitely interested in the results!

Although I am pretty dead set on making the jump to the EFR line I am so happy with my "cheap" S366 that a billet version with a much cheaper price tag then a 9180 sounds inciting. Especially since it will be fully rebuildable, will spool faster then what I currently have and may flow almost what a EFR9180 will.

Rotate86

5-7 weeks off for the other models to be available.

Rotate86

i see this morning BW have officially released the SXE range.and i have seen some sites that had pre orders already have in stock available to ship.now roll on reviews\dyno graphs.
iv had couple of different responses from BW retailers here in NZ about the larger turbine wheel being suitable.
i see the 61.5mm comes in the 2 options of turbine.the 76-67 & the larger standard turbine 80-73 across the rest of sxe range and the s366 from S series.
im looking at the 63 SXE but a little concerned about the potential lazyness of the larger turbine wheel.
so as all the info has eluded to the gains in the SXE are from the compressor cover.with the turbine being same material as S series.will these larger turbines create a noticeable spool response loss?is E85 enough to offset this?
surely BW have chosen this turbine size to suit there compressor side changes otherwise you would have to think they would have gone with the 76-67turbine through to the SXE66mm size like the older series?
i know they are new but thought id ask anyways incase someone has had a early play and was under embargo untill now.

We are prepping a car here locally that I am tuning with the sxe 8376. I bet it would only be 100rpms slower than a s360 with a 75mm turbine.

And yes pre orders are done, these turbos are now in stockm

Are the sxe compressor housings going to have an option for the 90 degree outlet? I haven't seen it available. I may have missed it however.

Rotate86

no i dont think they are/will.i wish though.they have taken the 90 option away but given the compressor discharge pipe the option of v-band instead.but in saying that i read somewhere that the next version of efrs possibly does come with the 90 outlet.so maybe they will revisit that as option for sxe.

Turblown

iTrader: (12)

No forward facing comp covers for sxe.

MaD^94Rx7

iTrader: (1)

I thought that if you have for instance a front facing s363 you can buy the sxe supercore and replace it?
Can this be done?

Turblown

iTrader: (12)

Nope. Supercore includes compressor cover, just no turbine housing. So you can use your old turbine housing from a standard s200 or s300..

Full-Race Geoff

they wont have the 90 outlet BUT instead have a vband option, just trim the compressor outlet down. Its an off-the-shelf Cummins/Holset vband clamp and flange, easy to find cast 90s or make one yourself

these are 2016 releases for B1 frame EFR only. (6258, 6758, 7163).



the B2 frame already have the same vband compressor outlet as the SXE, so they will not get 90 housings

That is going to be so sexy on sequential twin EFR 7163!

Low mount front & high mount rear with room for all that piping.
