Lookin forward to videos and dyno numbers 😍

How do you plan to prevent heat soak from hot side of turbo since your post-intercooler tubing routes right behind it?

massive boost pressure i would guess 😁

Fancy turbo binky to isolate the hot side + there's a fair gap between return pipe and other hot parts like exhaust manifold... I bet I'll be able to grab pretty much any part of the cold side bare-handed; there's still some room around there...

We're thinking maybe just ~8psi, but we'll see how the transmission holds up heat-wise. That part's the mystery...

Why run intake piping on such a roundabout route? Looks like it could have been more direct?
I'm sure you have a reason, just curious

Mostly intercooler location (in front of radiator), plus compressor orientation (out toward the driver's side) and intake position (in from the passenger side). Need to clear the radiator and fan shroud on both sides, which is actually pretty wide.

So, basically, we're just avoiding stuff that's in the way of big pipes, including the hood. Warm side dumps to the right, goes around the valve cover, drops down to the intercooler while avoiding fan/radiator. Cold return curves around radiator, straight back along passenger frame rail, then pops up to intake.

Fair enough. I love what you're doing. With major mods, some things are gonna have compromises, right.

I think there's probably opportunity to shorten that pipe run. I'm sure getting it running is a higher priority than rerouting pipes.

Check out "the official 1HD-T intercooler thread" in the Diesel Tech section of you're interested and haven't seen it.

Essentially the same configuration.
Clock the front housing on the turbo, redirect the manifold intake with an adapter.

On my diesel cruiser, I was looking at bringing cooler pipes through the rad support beside the headlights to shorten it up even more. Vehicle was written off before it got that far.

If members could please post the make/model/statistics of their various intercooler setups, complete with pictures, perhaps we could have this information stickified in one neat and tidy location.

This could take some of the mystery out of the transmission.

SOLD - Oregon : FZJ-80: newly custom built a343f transmission by atfspeed $3000

Greetings yall, I had this transmission built for my rig that I intended to install a turbo setup inspired by @scottryana . Life is moving me off continent, so Im now selling my rig and parts. I will attach the receipts, so you have an idea of what went into it. The builder atfspeed.com, out...

About 1990 I had a Heep CJ7 with a hot 350 with a built, hard shifting turbo 350 behind it that slammed the 1-2 shift so hard it would make the 33" Mickey Thompsons chirp a hilariously sounding deep bark.
I was goofing around once with a friend and I did a launch in 4low (front hubs unlocked) and spat my rear driveshaft out.
Good times surprising the ubiquitous mustang gts from stop lights, but the fender well headers out into essentially side pipes tipped my hand right away.
Fun times.

Have fun.
Have a good tow plan.
 
It's basically ready to tune. Prior to any tuning, the ECU now seems very confused...
So much AIR... so much FUEL... does not compute. 🤣

It will all get dialed soon. We might even have some full dyno pull results next week.

I would definitely insulate the next couple feet of exhaust pipe post turbo, maybe wrap headers too, (or insulated shrouds) and insulate the intake piping overtop of the exhaust. My inclination is that you'll be getting more heat soak than expected.

Also am excited to see numbers!

I agree. I tried an open element filter underhood of an 80 with a turbodiesel and it was way down on power in warm weather. Went to a new airbox pulling cool air from outside and no power loss in warm weather.

We'll see. There's a massive intercooler on it with rapid airflow...
