Thanks to CES and Steed Speed for making these works of art a reality!
With the EFR 8374, I have found so far that there is no room for a full size motor mount. CES was using a skinny solid mount with the 8374. Maybe CES and RallyRoad will develop a new arm and a new poly mount, but I am skeptical given the proximity of the subframe mount stud to the compressor inlet. Again, the EFR are longer than other turbos and this may not be an issue with precision or garrett. I have spent a bunch of time fiddling around hacking and relocating a mount, and it is not ideal.
The EFR8374 is also pushed so far over towards the fender that a 4 inch round intake is not possible, except perhaps with a skinny solid motor mount and some clearancing of the intake pipe for the balljoint nut. I am adapting down to 3.5 inches to get past the motor mount and ball joint nut. Shorter turbos probably won't have this issue.
The TS45 wastegate mount on the steedspeed is designed for a race car without AC. It will interfere with your AC lines if you have AC. There are two solutions. First is remove the lines and bend them to fit under the SAP bracket, then reinstall and recharge. The other is to hack off 1-2 inches of the SAP bracket and then bend the lines in place. This is what I did. This will be an issue with any turbo since it is up top.
The only easy part I have found is installing the manifold. Use the early longer studs. A socket wont fit so use a ratcheting wrench and a regular box end wrench.
The EFR8374 was also not so hard to install since there was so much room to the block side since the manifold designed to fit monster turbos, that I could reach the block side and trans side stud nuts reasonably easily (though I had to use a crows foot on the rear block side nut).
Hopefully those with PT and Garrett will have an easier time with the piping and CES and RallyRoad will come up with a mount and mount arm that work for the 8374 for those who use that turbo. Maybe even custom bent AC lines for those who do not want to mess with theirs.
The downpipe is pretty easy to make. I'd say it fits more like my original boostlogic downpipe. The boostlogic was pretty high mounted. The Steedspeed TS mani is probably about 1.5 inches higher than the regular TS mani that I have been using this year so I had to make another DP.
The WG pipe needs roughly a 90 off the WG and then maybe a 45 degree angle after the trans tunnel to merge into the exhaust. My install was complicated because I have a euro coolant reservoir and had to swivel the WG towards the fender to gain clearance for the coolant pipe. Anyone else can go down the back of the mani, a more direct shot. But either requires two bends to get down under the car. How you integrate into the exhaust varies, and some might not even bother (I tried an open dump years ago and it was not pleasant by my standards).
When the time comes, I will fabricate new AC lines. I don't like the stock routing anyway. I'm thinking of putting them through the inner fender well and using AN fittings with aluminum tubing. I won't give up on AC just yet.

Is anyone planning to install EGT sensors and/or an EMP sensor?
I'm looking at doing 1 EGT per cylinder, and a pressure manifold to receive signals from both banks for EMP.
I am liking that the manifold itself is easy to install. I plan on running a WG dump so it's a 90 and straight to the floor for me. And no a/c here, although to do custom lines with the magnitude of the builds we got going on isn't much of a hurdle IMO. Still waiting to hear somebody's install notes while installing a Garrett/PTE down there.
If you cut the stock line on the firewall and welded on an AN fitting and then went custom to the end of the main hardline at the shock tower, that would be fine. You would do the same with the small hardline, and reconnect to it at the shock tower.
Sorry, no pics. If you don't understand, you will once you get into the job. Hopefully someone else will take pictures and document everything. I am just trying to get my car back on the road and the frustrations from the unexpected projects are delays that I was not expecting.
Teflon hose can easily hold the pressure (with a SF of like 5-10). AN fittings can take way more pressure than an AC system operates at (maybe 250-300 psi max when hot and overcharged).
I've personally taken a -4 an aluminum fitting up to 12,000 psi. No leaks, it survived fine.
Aluminum lines (5052-O) are capable of 1500 psi so, ya, the pressures in the AC system would not be an issue.
I could use Teflon hoses but it's hard to do a clean install when you are restricted to such large minimum bend radius' of the hose vs the hard lines.

On an old GT35r headgasket car I worked on we just took it to a local AC shop and they made all new AC lines for it.
What I'm looking to use to help measure Exhaust Manifold Pressure:

I'd like to get Leen's input on where he thinks the probes best location in the manifold would be. Typically EGT probes get placed 1.5-4" from the flange face.

I too would like to install an EGT probe and an exhaust manifold back pressure fitting.

So if I were to purchase this manifold, what would be the motor mount use? Would I have to to wait for one to be develooed, or is there something on the market that gets the job done. I'm really thinking of pulling my top mount off.

I think you can get the 1.5 inch minimum. Manifold is very sturdy, plenty of space on top. Only on the runner closest to the wastegate will things be a little tight due to the WG, but you should be able to get close to 1.5 inches from the flange.
What are everyone's turbo plans so far?
I'm all over the place on sizing...depending on my mood.
