[Closed] Borg Warner Efr Series Turbos

[GTScotT]

I also believe the last time he updated on power output it was something like 240? So he's still waiting to see what his final output is.

Otherwise your notes are spot on.

[Skepticism]

Oh shiet.. yeah, just remembered that it was the ART silvia with 300kw

That was with a 6758.

BTW any idea why Full-race might want my full name for a shipping quote?

I'm too paranoid to give that info out until I'm sure I want to get it off them. But that depends on shipping price. I'm sure there's a reason though.

Wow you're paranoid lol. Maybe they'll fly over from the us and rob you of you "awesome" parts...

Haha. They just want your info for proper filing and reference so there are no mistakes (numbers can be typo'd, full names, not as much)....

I'm sure they won't come haunt you if later decided to go for a cheaper Honeywell turbo

Been at World Time Attack in Sydney the last couple of days......1st and 3rd place cars were running BW EFR turbos, 9180 and 8374 (although I think the 8374 was a bit of a "special model".....care to tell Geoff Racier?)

What a fantastic event! With Japanese superstars like Tarzan, Nob, and Under Suzuki there.....

......Now they just need to build some cars to takes of the dominance of the Aussies (with one Kiwi driver

so jealous you got to attend!! great showing all around, proving the EFR turbos on multiple vehicles in competition. EFR9180 turbos were used by PRO class 1st and 3rd places Tilton and Nemo.

Open class we had 2nd and 4th places on EFR8374 (vsport evoX and nik kalis evo 9)

and 1st place BC racing r32 GTR used ETS-pro.

also noteworthy is 1st place for clubsport FWD with EFR6258 on Judas Jones' colt ralliart, prepped by Todd Munkman. he wrote to me

"Turbo wise, it's epic. Power comes on hard and spools quite well for such a tiny engine. Running boost by gear so gate pressure (15psi) in first and second, 29psi in 3rd-5th."

From what I've seen a T4 Twin Scroll 1.05 A/R EWG will spool faster than T3 open scroll...and is better across the whole rev range. I would be opting for that option if I go an EFR...

i agree, t4 twinscroll is the best configuration for the larger B2 EFR turbos. however some people want to keep their existing undivided setups so we offer both. they can always swap the turbine housing/manifold later on to a divided to get the twinscroll torque curve & midrange power

I am only after a punchy 260+rwkws from my Cossie. The thing is low compression so happy to run up to 26psi. I just have to get my head around running a turbo with wheels the sizes of the EFR 7064 and 7670 and still be able to get good reponse and torque as the engine only pulls 7,000rpm. I think I would be happy with 6758

for 350whp / 260wkw up to 7000rpm on a 2L engine-- i agree the EFR 6758 is a perfect match. In undivided config it's extremely simple to plumb if you have an existing manifold

sounds like the twin scroll T4 7163 will be the go. What hot side options are there with regards to IWG and A/R for the T4? Geoff...will these end up on your site or should I just drop you some mail in a few weeks?

The new 7163 T4 twinscroll turbo is very impressive, although it is larger than your stated airflow requirements. it is available as 0.85 a/r singlescroll (iwg T25, iwg vband or ewg vband) and the 0.80 twinscroll T4 IWG. 7163 production is going on right now. We are not going to list them on our site until the reservation lists are filled (too many phone calls about them as it is), people on our reservation lists will be getting the turbos first, if you want to put your name down it doesnt cost anything we will contact you once they become available with an option to buy. thanks everyone for your patience still a few weeks away but its happening

thanks for that link, i remember speaking with Scott (tuner) when they did that setup, he was over the moon with it. Now hes dying to try a 7163 on there next

we try to keep organized and detailed records, that way when an estimate is emailed or an order is placed there are no mistakes or confusions. Very important especially when shiping to the other side of the planet.. although with a screen name like "skepticism" i thought this was a perfectly appropriate post

I really like the look of the 7163. Also, my .63 gtx3071 hit 20psi @ 4200, with a giant intercooler pipe leak.

if youre interested in the 7163 we will have details at the end of this week, pricing and availability. with regards to your gtx3071 it was on a .63 where our test was .82 a/r (for the sake of comparison to the EFR's .83 a/r)

I think the best im ever likely to achieve is desired boost by 4000rpm. Don't get me wrong, I like my current setup, but my car is currently apart getting various work done to it and I'm in a position where I could easily change turbo now if I wanted to, or if an opportunity arose

I would expect the 7163 to have full boost long before 4000rpm. also most of the t4 twinscroll EFR turbos like 7064 or 7670 should also acheive that. The singlescroll might do it but it would be close

the internal gate version is too long to fit into half the cars I work on. The external gate versions are looking better each day.

typically the length of the IWG turbos is not what makes them hard to fit - its the actuator and bracket (which we have a few ways to work around it). For street cars its worth the effort required to design manifolds/DPs which utilize the IWG, although EWG does make fitting on traditional kits very simple. we are happy to suit either option

This aint no RB mate.

Hey Geof, not too much related but was curious. on your 700whp build, you had 3 inch exhaust hen ? Haven't thought about going free flow 3 inch or 3.5 inch to see extra gains ? Wouldn't a turbo likke the EFR benefit from the extra free-flowing exhaust resulting in quicker spool ?

[discopotato03]

Geoff you'd probably see this as a backwards step . Anyway , R33 RB25s need a spacer to fit a GT3076R on the std manifold so it's probably not impossible to make the plate a twin entry T3 to twin entry T4 adapter plate . Going from smallish ports to the larger twin T4 ones obviously isn't ideal but it would let you mount a TS IW 7163 on the factory manifold .

http://www.ebay.com.au/itm/like/130895042084?lpid=87

It may be possible to port the manifold a little at the flange to get the ports a "little" closer in size .

Workable or don't bother ?

You could CNC a flange plate with ports the same size as the stock manifold ports, but with threaded holes for the T4 studs and countersunk holes for use of alen head bolts to fasten to the T3 flange.

You wouldn't need to port them to be similar in size for it to be effective, as long as there was no hard edge in the flow path. Most quality manifolds these days have smaller collector discharge ports than the turbos entry (6boost, MXP), and they are known to work fine.

Do it, Disco. Be a pioneer.

As per expextations the Evos kicked butt though its too bad there were few GTRs in the upper positions.

What happened to bright's car I wonder? The car wth twin -5 did substantially better... Did he have issues?

His car was y favorite going in!

The s13 did sick we'll!

Poor nemo couldn't hold a headgasket...

Was an awesome event, I will definitely be back again next year

Bright's car was plagued by electrical gremlins

Too much boost and too much stock ignition system? Lol

[Lithium]

I'm sure he can add more if he wants to, but in short - no. Shame it didn't work out for them though, I was really keen to see how that car would go too... everything there to be an absolute animal!

[bri73y]

Absolutely nothing stock about my car......

Unfortunately we had issues as Lith has already alerted to. Something electrical was taking out components daily.

Thursday we lost 4WD, Friday we lost power steering and fuel pumps, Saturday we lost the ECU and M&W ignition unit.

Had all the right people working on the car however we were unable to locate the problem.

Never made it across the finish line under power unfortunately.

[bri73y]

Almost forgot, this was Thursday too.

Popped a couple of shims when Mark Berry was driving......

Had a false neutral on gear shift.

Electrical gremlins are the worst, bad luck mate. Get them sorted and there is always next year

in that photo, I agree - the new EFR7163 singlescroll EWG vband inlet/outlet is your best option. we have a very small amount of these coming in over the next 2 weeks

that's exactly what ive been suggesting for you to do... I think weve been talking for close to 6-7+ years now, starting at that evo forum reminiscing with Khiem about NS111 9 blade turbines ... this would finally be the "magic" spec youve been waiting on. no BS i have never told you to buy any turbo before, this is the one for you. we have even less of these twinscroll 7163s coming in than singlescrolls, but there will be a couple

i always used 3.5" exhaust on my rb26. competing in street tire class, which requires a catalytic converter meant 3" would be too small. 4" is a bit too heavy and much louder plus it doesnt provide much power gains over 3.5" for the power range im interested in

Edited October 22, 2013 by Full-Race Geoff

[NismoSTune]

3.5" would be nice but the nice tomei TI is like 3-1/8" or something

[Angus Smart]

Fyi, It just cost me $160 to ship a turbo over (2 day delivery)

wish i had just used Geoff/full race as i ordered mine from Vivid 3 months ago, they said it was in stock at the time... It shipped today should be here Friday.

Will need to order manifold and gates soon.
