Wow people are really hating on your build!
Rear mount turbos are a great option for vehicles with tight engine bay space. 4-cylinders are easier to turbo for this reason. Lag isn't too much of an issue if you have the right sized turbo with the right equipment. Modern turbos used for vehicles in 2020 virtually have no turbo lag at all, some build max torque as low as 2500 RPM's (and that's not a diesel). Technology really has come a long way. Heck, there's even legit electric turbos, Volkswagon make them several years ago and they are starting to go into mass production more and more each year.

I’m just gonna assume that was directed at me because I didn’t see anyone else mentioning lag. I’m definitely not hating. I’m here because I love turbos. Having owned both supercharged and turbo, and one car that had each installed at different times, I will almost always pick a turbo over a supercharger. Op wants to go turbo? that’s cool and I wish him best of luck. Would love to see a solid turbo solution here.
As advanced as turbos are there is no getting around the fact that the exhaust is gonna have to travel all the way back there and past the cat before it can gets to the turbo and start to spool. Lag will be an issue

THIS IS BAD*** the SC / Turbo combo was amazing to watch. and to the OP I am subbed!! Depending on your level of skill, and access to parts, I think a turbo setup could be done for 800 bucks no doubt. At least for the mechanical portion of things. I know diddly squat about any sort of tuning or expenses associated. You got this!

Too bad the OP didn't link the previous builds, but the guys who have done remote-mount setups one these trucks didn't complain about lag.

Picked this up today (or ordered it). Still just compiling parts. Not all my exhaust stuff has come in yet, so I’m at a standstill on any sort of fab, and I got a lot of housework to tackle.
Amazon.com: Bosch SP0F000050 Style Line 2" Mechanical Vacuum/Boost Gauge (Black Dial Face, Black Bezel): Automotive
Total with tax/shipping came to 38.15
I also did a bunch of spark plug research. Clownmeat said he went with a 2 stage colder plug (NGK bkr7e), but that plug isn’t twin tipped. I found the BKR7EKC-N that is twin tipped, but that gap is a lot smaller than stock. Decided to see what the S.C. guys are running. Looks like they recommend the BCPR-7ET’s, which I think is what I’ll ultimately spring for. They’re 6.87 a plug!

Sorry, just assumed his build thread was already stuff of legends (turbo, home cooked paddle shifters, started on a home cooked 7th/8th injector), lol. I’ll swing back by the original post and edit it to include the link to his thread.

No not necessarily you, mostly the first page comments. I do get that the longer the intake pipe, the more it can't escape the fact that the pipe has to pressurize before the intake does, totally get you there. And a rear mount turbo pipe will be long. But if one puts in a quick spooling turbo it may not be felt too much. I've seen some rear mount turbo systems that are a blast to drive and doesn't lag much at all.

Did some reading on the forums. I got sidetracked by the under hood turbo builds though lol. My only experience with turbos is on different platforms for different purposes. I shouldn’t have brushed off your comment about using the right size turbo for this to work with minimal lag. You were right people have made this work and I didn’t see complaints about lag

All of my exhaust parts finally came in. Managed to fab this up today. Decided to wait to put my elbow and flange on until I have the turbo and muffler to make sure im cutting the pipe at the right place for where I want everything placed under the vehicle.

Also bought my turbo and a muffler today.
Not sure if I mentioned this before, but I don't want it to be straight piped after the turbo because im concerned about it being too loud and just annoying to drive around. I'm also concerned about having an obnoxious turbo whistle all the time. I live around several large diesel trucks that I can hear coming from a few blocks away because of the whistle, I don't want to be that guy. Maybe when I was 18, but not now, lol.
So, I bought a cheap, small muffler (single chamber, 2 baffles) that should help quiet the exhaust down even more, and should help prevent the turbo whistle.
Amazon.com: AUTOSAVER88 3" Inlet/Outlet Muffler, Single Chamber Universal Stainless Steel, High Performance Exhaust Muffler For Cars: Automotive
For the turbo, I went with the specs of what clownmeat used. He seemed to have decent results. I did go with an internally gated turbo in lieu of buying an external waste gate. I'm sure like all ebay links on threads...it'll die before too long. So run down of specs. Its a T04e, Compressor A/R 0.53, Trim 57, Exhaust A/R 0.63, Trim 58.
T04E T3/T4 .63 TURBO TURBOCHARGER COMPRESSOR 300+HP W/ INTERNAL WASTEGATE V-BAND | eBay
Cost for each
Turbo - 137.75
Muffler - 27.55
Brings my total project cost to
$348 even

Sounds like a cool project.
How do you plan to route oil back to the turbo?
What do you plan as far as heat shielding?
Are you running an inter cooler or just plumbing right into the intake?
Having spent plenty of time under these rigs I can’t imagine it will be fun to fit a turbo, oil lines, and air pipes under there.
Looking forward to seeing what you come up with.

Wouldnt it be better to get it supercharged for more low end torque for towing?

There is a plug on the block near the oil filter that I plan to get the supply from, return will go back up into the oil filler cap.
No heat shielding. Since I’m putting it where the current muffler is, there is already a heat shield there.
Just plumbing it straight in. I’ll have to go back and look at the numbers from his thread, but clownmeat saw intake temps astound 125 I believe. The length of intake piping essentially acts as it’s own intercooler.
Edit: Went and dug through his thread. He said “ So as you can see here with a rear mount turbo I am seeing intake air temps at 100 degrees normal driving and about 135 degrees with a pull after pull workout. I think it's pretty awesome compared to the 200+ degrees the supercharged ones see. One more reason the stock fuel system can keep up without pinging also.”

So your more or less copying his setup.
Do you have a lift and a 2” body lift like he has?
It looks like that body lift was important for the air pipe routing back to the intake.
