+/- 20% of vertical for the oil drain line. I also recommend that anyone installing one read the EFR tech brief. All questions are answered there.

I'm a little scared to turn the boost up on this motor. The build has begun on the bullet proof sleeved 2.34L motor though. That one will take whatever I can throw at it.

Me?

If so his boost pickup was giving him issues and I was told to disregard. Actual boost is 15psi to redline.

Only referance to 20 degrees is left or right. My issue is nose up or down for which there is no spec just says should be flat which is not an option in my case. Garrett give a spec on this

https://www.dropbox.com/s/4n0b35w6ckax3z7/m3.jpg

Refer WRC turbo location and angle

Call Borg, their tech people will either know, or at least be able to find out.

Re-reading the EFR Tech brief they say mount the turbo as level as possible longitudinally and avoid to much nose up or nose down attitude. It sounds like they only tested it in the horizontal position so I guess its up to you to push it on the angle and report back when oil starts getting past the seals.

"The bearing housing oil drain should be pointed straight downward where possible, and at most 20 degrees tilted right or left. When routing the oil drain line, try to keep it running downhill all the time and avoid horizontal spots or sharp bends. The oil should drain to the block or pan in a low pressure region above the level of the oil bath. It is not recommended to install the turbo considerably nose-up or nose-down. It was validation tested to be installed “flat” with respect to the ground." ==> from EFR tech brief

You're aware that the WRC turbo in question that mounts almost vertically cost about as much as a new Subaru if not more. I wouldn't expect to find many other turbos that would like that position.

That WRC turbo is also replaced after every race, as it is also fed anti-lag. At least that's what a WRC tech told me when looking over the car.

My tuner claims he had one on the dyno, nose up at 20 degrees an it was leaky, the other ones were under 15 degrees and held fine, so from first hand I don't recommend more than 15 degrees

Default EFR 6258 v-band and flange

Can any of the vendors supply me with v-band flange and clamp x 2 for my two EFR6258 turbo's. My email is tony.dobnik@gmail.com . Sorry to be off topic but am desperate for the supply of these parts as they are stopping me from having my car up and running. My postage address is 38 Bathurst Rd Orange NSW 2800 Australia. Locally I have had nothing but run around with no results and one US supplier after a week of emailing has told me two week wait as out of stock.
Hope someone can help.

Cheers,
Tony

Buy from treadstone. They currently sell the best clamp for the EFR v band and have 2 options for flanges. One flange option even lets you run a 3.5" downpipe straight off the turbo.

Well that sucks. I guess I would wait for those and just grab the crappy one from Borg Warner which you can buy from full race or any other BW dealer, if you need it now. The one from BW will likely last one or two times taking the turbo off before you turn the threads into mush.

FYI I get ~15 psi at ~3200 RPM with the 6758 ... on a 2 liter (EJ207). It spools very close to a vf39. A 6258 is going to spool very quick on a 2.5L.

It's a street car that'll see occasional the drag strip or road course.

Also, this was my first trip around the block with the car, very little throttle and almost no boost. Man are these turbos loud!

Don't run your throttle body like that. At partial throttle it is gonna mess up flow from cylinders 1/3 and 2/4 due to how the flap works. At idle and wot it would be fine, but not worth the risk IMO

The car is ridiculously fun to drive and proves to me it was worth the wait every time I start the car up.
how do you like that link ecu? is it the plug and play one? does it retain cruise control and ac functions?

I love it. It works as advertised and I love the software and capabilities of the unit. Mine is not the replacement board model its a wire in model with an adapter harness that connects my factor harness to it. You get a few extra ins and outs with the wire in model and mine will drive high and low impedance injectors.

I've been told that in a future update they will implement cruise control and currently the inputs are there in the ECU when that becomes functional. The car still has A/C.

They used to sell an adapter harness but not anymore since they have the PnP replacent board options. Now its either replacement board or full wire-in.

I have some pics of the adapter harness in my build thread if you want to check it out.

Have anyone good logs or dyno graphs of S200sx 7670 and S200sx 8070?
on 2.5 subaru motor with twinscroll header

would like to go with fast spooling turbo, 7670 need to be purchased with additional (smaller than std. 1.22 A/R) turbine housing so it's kind not so cost effective as 8070, which could be then easily swapped with s300sx 8375 for mooore power and also it fitted with 0.91 A/R housing that should give good response and spool.

so need some more info to make decision

My S400SX FMW 1.25 AR T4 build:



Should be turning it up to the 600-700 wheel range in the near future, then I will need to work with the fuel system to squeeze a bit more out of it.

2.6L ej257 (79mm stroke, 4" bore), sleeved, o-ringed, cosworth crank, spinning 8800
v7 ej207 heads, cnc'd, ported, polished, +1mm valves, springs, retainers, Kelford 280s
ARP 625 outer studs, 13mm inner studs

Will be running e85 then switching to e98 or ignite red when turning it up.
