00 too many turbos
white

Default

EFR6258 and EFR6758 available now in .64 a/r housing only, do not underestimate either of these turbos!!! considering the ultra low inertia lightweight rotating assembly - on a 2.5L - i doubt you will see much improvement vs cost on such a small twinscroll EFR turbo but it will be interesting to find that out once the turbos are available next year. Summer of 2013 (we are told july) is when EFR 2 will debut. EFR 2 will include the 1 new turbo and a bunch of new housings:

mixed flow 7163 turbo (same turbo as initially discussed in this thread, but production versions will have ~12% more performance over the version he tested)

new EFR2 turbine housing options:

-twinscroll 0.80 a/r for 6258/6758/7163

-singlescroll .86 a/r for 6258/6758/7163

-vband inlet/outlet option with IWG for all B1 singlescroll turbos

-vband inlet/outlet option with EWG for all B1 singlescroll turbos

-1.45 a/r for EFR8374 and EFR9180, ideal for larger displacement motors such as 2jz OR anyone looking to make a legitimate 1000whp on a single EFR turbo. testing on this thing shows its a monster

i am attending PRI in orlando, Florida this week and will be sure to snap some photos

New models are great, but they should address the production issues too...no point getting everyone excited about it and realising that these turbos are gonna be like unicorns...

Thanks Jeff! Oh I don't underestimate them at all. The SS 6258 and 6758 would be the cats meow for the 5 cyl Audis (including the UrQuattro) and VWs, as well as < =2.0L engines.
I quite like the decision to use a .8 a/r twin scroll, should give a little more on the bottom and a little more on the top.
I have no doubt that the BW team saw no benefit in spool with the .92 a/r twin scroll over the .64 single. I didn't expect any either, however the top end would've been quite nice on the larger engines, especially if said engine had larger cams (mine doesn't).
Unfortunately, everyone seems to focus on spool with the twin scroll housings, when it is only 25-33% of the equation.
I think the .80 a/r twin scroll is probably the better balance.
Played around on MatchBot for a while interpolating the .80 housing on a EJ257, looks like I could have a 5500 rpm power band if I wanted to do some work to the internals so survive at 8000 rpm.
That 6758 TS is going to be a star on the right sized engine (2.3-2.5L with 8000 rpm rev limit), as long as 400 WHP or less isn't a problem. Most seem to want more though....
Thinking that the .86 a/r SS housing would be great for a nice torquey 240Z-280Z if the owner wanted to keep the revs down to around 6000-6500 rpm.
Lots of really great possiblities with the B1 Frame when they get some more housing options out there. The EFR 7163 looks like it's going to be a greatly versatile piece.
How did PRI go? Any news?

It's a kit. Give FR a call for more turbo options.

hey Geoff, so i have read the thread and had some input but with there not being TS exh sides for the 7163 in B1 frame what does the twinscroll 0.80 a/r for 6258/6758/7163 consist of for inlet flanges? are they going to be in B1 or B2 frame. I am going to wait to see what the new products look like and prices but i am set on a efr turbo. not going to waste my time with the dom1.5 TS on my ej207 but just make a twin scroll to single scroll up pipe (1.5 scroll i think they are called) and mate a flange on top of the exh side i choose. or do you make 2-1 up pipes that bolt up to ej207 exh mani?

I was thinking about that the other day. Even faster spool in a stock location package.

Wow, so finally v-band inlet?
Sucks I have to wait so long. The 4-bolt t25 is way too tight. V-band is a no-brainer. I was trying to get non-coated 6758's from a local dealer to mod to v-band, but he hasn't got a response yet. Seems like a waste of time now.
Glad to see you guys are moving forward with new stuff and pumping out the goods.

The OP is the SoCal tuning shop Yimi Sport. They do a lot of testing for Full Race and get pre-production parts to test.

Holy **** 1500 for the kit?! I posted once when this first came out expecting it to be 3k+


This changes my decision potentially. Crap. Lol



Edit, never mind it is 3k. Oh well.

So you have their twin scroll kit, not the kit talked about in this thread?

Would the S/S B1 6758 benefit at all from the FR 1.5 scroll mani/uppipe? I read a few pages back that if there is enough demand they would consider making a T25 flange for the uppipe. Should I read between the lines and assume if they don't offer different flanges for the uppipe, the "stockish" EFR line probably would not benefit? I am currently on a stock manifold so I would upgrade eventually anyway, but not at this price point for nothing. Thanks

bru1212 - our stock location EFR kit is designed towards simplicity and fitment on a "typical bolt-on subie" - Right now we are developing a new lower manifold (1.5 scroll style) to suit 2-bolt up pipes like this kit... that would be my recommendation - for anything more than that, rotated twinscroll would be the call..

Hi rasheed, the 1.5scroll up pipe never really gained popularity and our dealers kept asking for us to support the 2 bolt up pipes with our lower manifold, so the decision was made to move forwards with a new 1.5 scroll lower and 2 bolt up pipe rather than retrofit the older and more expensive 1.5scroll up pipe

That's funny. I asked you guys about doing this about 3 1/2 years ago when I had an AMS rotated kit and really wanted a Full Race quality header, lol. Glad you finally came around.

I'm trying to picture what a 1.5 scroll lower looks like with a 2 bolt flange.

Sounds like a step backward in design just to make it more universal.
