A bit more progress - as soon as I catch up with the general workflow around here today I'll do my best to address the questions that were asked, for now:

Reminds me of an upside down wittyworks manifold with v-band. I kinda based mine off that and my measly td04 spools like ****

Let's say it's a comfortable bend, no more aggressive than what's been seen in the past. The first downpipe will be pie cut but for production reasons and cost, it's going to be a simple bend. More shots to come that will better outline this.

Can the manifold be flipped to bottom mount. Because that would be epic.

The bolt holes are in different locations on the top and bottom of the flange.

With the right flange it could be done. No real use would just be cool though.

That water cooled fixture plate is nifty as ****.

I'm interested in seeing where you run the EWG off of.

Also interested in the spool characteristics of the 6758 and 6258 with the .80AR vband housing vs the .64AR T2 housing.

And have you considered the cast tight angle 3" OD sch10 elbow for that downpipe elbow? Threadstone sells them as their own proprietary thing but I highly doubt that.

I assumed that was for backpurge, no water return/drain line. It is neat though.

I assume that there will be brace (or 2) from the manifold connector to the engine block? There's a lot of weight on the runners with the turbo hanging out so wide so they'll be prone to cracking.

Also, please confirm whether or not this solution/turbo-orientation has any boost creep issues if using the IWG.

I asked NitroDann to build me a low-mount soution that allowed me to retain the A/C and I wasn't fussed about whether or not the P/S had to be removed and he came up with a solution that allowed me to retain both (I later got rid of the P/S).

The problem with this setup is that the wastegate valve is binding and I get MASSIVE boost creep. The issue is due to the fact that the wastegate actuator shaft needs to twist somewhat due to the clocking orientation of the turbo intake (where the wastegate actuator is mounted to) relative to the wastegate valve actuator (mounted on the exhaust housing) no matter how the shaft was bent to actuate the valve.

We sent the turbo off to turbo specialists to try and figure out a wastegate solution that preserved the clocking orientation with the position of the wastegate and their best solution was a weak-sauce wastegate actuator (6psi) with a modified shaft that now limits the boost creep to 10psi. I was hoping they'd come up with some ball-joint wastegate valve actuator but all they did was modified the shaft by extending it and bending it.

Despite the fact that you can clock the EFR turbo to multiple positions, I believe that the IWG is really only designed to work for a small range of orientations (eg. the common high-mount solution where the wastegate is mounted between the engine block and the turbo).

nb4 water cooled manifolds... lol

Also, Will this possibly have a option for a t25 flange?

Lokiel, the turbine housing FAB is building his setup around has no IWG. Its v-band inlet unlike the T25 flange B1 frame EFR we are both using. He will have to add an EWG to this, thus my question earlier in the thread.

EWG location shown below. This location was ideal for obvious routing reasons and for those of you who have a little hoon in you and wish to rotate your EWG and dump through the hood (blame the Evo guys). Also, this makes routing the manifold reference lines, away from heat and short.

So I'm surprised by how clean the BW compressor and turbine housings are. I'm guessing they addressed the form issue they were having(in reference to EO2K's housing)

Looks like it clears the heater core lines and brake master easily as well, obviously need to cover the reservoir, but that is a given.

Srs question: is the wastegate angled 90° to the flow of exhaust going to be able to flow enough to keep up? I'm no engineer but fluids (such as exhaust) will generally take the path of least resistance, and the .80A/R housing isn't going to provide a whole bunch of challenge.

Again, I'm not a fluid dynamics guy or injuneer, just a casual observer. I may also be slightly drunk and shooting off questions.

My housing has AIDS and cancer. Everything else about my EFR is top notch: great surface finishes, properly deburred holes, clean champers and radii on all machined surfaces, properly tapped threads... including the compressor housing. Everything except that god damn turbine housing. It didn't bother me at first because everyone said "thats just the way they are now" but the more EFRs I see, the more annoyed I get. FUNCTIONALLY I'm sure its fine, its just ugly.

Eh, I don't see a downpipe bolted to it

It still looks amazing. This is almost exactly what I had in my head when I was dreaming things out
