They have to be the sexiest turbos hands down.
Raffi, Looks like plenty of room diameter wise but they are a bit longer on the hot side with the IWG and a tad longer on the cold side as well because of the BPV. Is the up pipe your 2-1 UP? Seems like it could be positioned slightly more forward in position. Agreed they are sexy! I think the 7670 is in my FSTI's future with my new motor build next spring. How will the availability be come March? Will I need to reserve some thing soon? Do you want to PM me to discuss?
Thanks

If you want one anytime soon i would recommend calling and putting money down. I believe im #1 in line for the 8374 with a mid jan ship date. I heard they are nearly sold out and who knows when they will show up after the first batch.

THANK YOU to everyone who stopped by the BW booth at PRI. it was great to meet you guys and show you the EFR technology in person

As an experiment in the lab, the BW engineers simulated a metal piece shooting through the turbine wheel (similar to a broken piston or a broken valve exiting the engine) and it obviously damaged a blade on the turbine wheel. Then they tested the damaged turbine wheel turbo to see what the loss of efficiency was... amazingly the performance was almost identical to the undamaged turbo. <i do not recommend doing this!!!>

Full-Race has a very innovative billet aluminum CRV cover coming soon

GT: plastic bearing cage, stainless balls, metal bearing race
EFR: metal bearing cage plated with silver to prevent galling, ceramic balls, M50 bearing race

correct. fyi- the gt35R bearing cartridge is also the same as gt30, gt28 and gt25

How much more response and spool would there be, minimal or considerably more? You've always stated that in a twin scroll configuration, it likes a larger a/r turbine housing. How would it behave on let's say my motor: 2.5 lit forged sti block 8:5.1, light porting on valve seats, 272 BC cams (not true 272's, maybe more like 260ish duration) which is ok so I don't shift to the right so much.
this is a great question. You are correct that I traditionally like large-sized A/R turbine housings for twinscroll setups, However I learned a lot working with the BW team and turbine efficiency tends to go down slightly with too large A/R becuase you are asking the wheel to flow more than its "sweet spot". As a result the .92 a/r is actually damn near the sweet spot for the mid-highish flow levels, and the 1.05 is the way to max out the turbo for the high flow and high boost setups. For twinscroll setups on a performance application - above 1.05 is too big, and below .92 is too small.

This was really driven home to me when testing a bw prototype turbo last year on my R14 during the modified magazine shootout AND the previous year with yimisport's 08 STI. I did not take their advice to use the .91 and instead I ran the 1.10 a/r based off my initial instincts and experience with the s300sx line mostly on evos and hondas. I was thinking it would be a bit easier on the motor (we had a stock bottom end in the car) however now that ive gone thru data and logs and dynocharts - the .91 a/r was ultimately a much better powerband but because i was rushing to get ready for the race I did not test it until after. we're always learning. the cars would have definitely gone faster had we run the smaller a/r hot side. for this reason i am running an EFR 8374 with .92 a/r on my RB26 next year... and ill lose the complexity, weight and hassle of the external gates

Ultimately the behavior of this turbo on an engine like you highlighted - 2.5L with mild headwork and 264-272 cams (kelfords are my preference) i would lean towards the .92 a/r with internal gates. the subaru VE is not ultra high, and unless its a race car which will live at high boost and high rpm, im going to want the quicker response.

that would be a fantastic setup, incredible powerband with massive torque and spoolup would be a rush. Sorry we do not have plans to mfg a manifold for the ez30 at this time

that is not the 8374 from what i can see - looks like an efr 6258 or 6758 .64 a/r

this is our singlescroll T3 up pipe, which bolts to a 2bolt stock header or any of the aftermarket headers (not counting full-race or any 3 bolt lower manifolds). can not position the turbo more forward - the intake manifold is there. btw i see your screen name do you ride mt. bikes?

I do realize that there will be an intake manifold there but I was wondering about the position of this turbo because they are longer front to back it looks like they could rotate counter clockwise and move forward and not interfere with the intake. Why yes I do mtn. bike as much as I can. From MTBR.com? You ride as well? It's ski time now and I've got some big new Wagner's to ride!!

Thanks MA! I figured as much but wanted to be sure what I was looking at. The 7670 T4 .92AR TS should not be any bigger overall maybe a bit taller top to bottom. Would you not concur?

Any idea when you will have complete turbo kits with the efr's and ts up pipes without wastgates or flanges?

N2oiroc, if we were having serial numbers on them, yours would be #0001..haha.. You were the very first in line. Nasioc is gonna have to make a EFR forum pretty soon for the suby's with transplants..

Time to clear up some rumors, I have been receiving inquires about these from customers that are being told that all of the EFR units are spoken for, the EFR turbos are not sold out!!! Please remember that just because one vendor has presold all of their units, this does not mean they are all gone!

These units are set to arrive this week and are currently available:

179150, EFR6258, .64 A/R T2 W/G
179388, EFR6758, .64 A/R T2 W/G
179351, EFR7670, .83 A/R T3 W/G
179258, EFR8374, .83 A/R T3 W/G

The twin scroll units will be arriving late January but I would order sooner than later. They are selling fast as well. Please do not think that they are all gone!!!

Those interested can find more information, including pricing here

good choice - the 7670 .92 a/r IMHO is the optimal match on a street EJ25. The twinscroll EFRs will arrive early february, it is not possible to get one earlier

The EFR turbokits are in production right now. ordering the manifold with no wastegate ports/flanges will save $

twinscroll turbos are tentatively scheduled to leave BW the last day in january, arriving at Full-Race early february.

Hey Geoff, I'm curious what kind of "location" the 7670 TS with your exhaust manifold will be? Raffi was telling me the EFRs won't fit your old TS manifold so I'm assuming it's not the same as a rotated kit? Would you happen to have any pictures of a 7670 TS in a subaru?

Emmanuel, it's not that the EFR won't fit the manifold, it's that the internally gated model require a specific downpipe. They fit the manifold just fine, but since the EFR that you are getting is internal wastegate, the turbine housing is elongated which means we had to fabricate a new version for it.

The external wastegate EFR turbos WILL fit our gen2 twinscroll kits - in fact the EFR turbine housing fitments were developed around these twinscroll turbo kits (many many hours spent on that!!). The main difference is that the EFR kit can be ordered with or without wastegate ports - and that requires a different downpipe to accomodate the high flow IWG

The EFR turbos will NOT fit our old gen1 twinscroll kits.

i do have photos of all the twinscroll EFRs in a subaru, id be happy to post them up tomorrow morning for you

edit: i just checked, we've got pics of the 7670, 8374 IWG, 8374 EWG and 9180 EWG all in twinscroll and singlescroll

So piping for the intake should be no different then a non EFR turbo right? I'm in the process of trying to figure out the intake side of my build now. I want a reverse intake that will keep AC, PS and ALT. I'm trying to figure out if I should have the piping like how Yimi did it for their 08 or have the piping go straight through the top rear of the engine to the drivers side front and come out the pass side front. Any opinions on this?

correct. flipping the intake manifold to acheive the shortest possible charge piping route is smart, and our Full-Race charge piping is by far the easiest way to do this - particularly on the cold side.

its pretty easy to route the piping under the intake manifold OR how yimi did on their S300SX (soon to be EFR), both routings are fine:

How involved will Yimis setup be? Do you offer that? Another option I have requires unwrapping the engine harness and some other things. Will I have to do that as well?
