Nothing at the moment. Putting the expansion tank over there would cause a bunch of hoses to be run back and forth over and under the radiator. Not ideal for the plumbing.
You know how Rush hates running his hose back and forth...
 
More going on…

Bought a Donaldson Cobra-head intake boot.
Unfortunately, it interferes with the mechanical fan.

Fortunately, the lip of the boot that clamps onto the throttle body has plenty of room for trimming, so rolled the dice and cut 1/2” off from the edge using a hose clamp as a guide. Now there’s ~1/2” clearance.

But wait! The boot has interference with the idler pulley! A smaller diameter pulley would be ideal, but I couldn’t find anything that was surefire, so the next best solution is this idler pulley relocation bracket.

There, now everything with that puzzle piece is ironed out.

The combination of a lower profile intake and a mechanical fan makes things problematic.

I use these intake elbows and have never had any fitment issues, maybe the Donaldson is different dimensions?

Just went out and measured against the dimensions shown on that site - same dimensions. Had me worried there for a minute 😅
Sucks they don’t have a silicone cobra-head in 4”!
I like that carbon fiber intake piping they carry - how do you cut carbon fiber pipe? Probably not on a chop-saw?!

Pretty sure you can cut it on a chop saw. Just use the right blade. It's probably not much tougher than PVC but it has fibers in it so you need a very smooth cutting blade like a diamond tipped cut-off blade or you will not have a smooth cut.
 
More “whack-a-mole”! Or maybe whack myself in the forehead.
The style of radiator with the upper inlet on the driver side is going to require another level of plumbing that I wasn’t anticipating.
Tried hacking up a stock 2003 Chevy Silverado upper radiator hose to see if I could make something work. It *could* work, but I don’t like it and wouldn’t trust it for any long term use. The best route seems to be directly over the top of the fan (above a hypothetical shroud) as opposed to snaked over the radiator tank. I think what I’m going do is make a hard pipe that ties into a 90° section of hose on the radiator and a 45° section of hose on the water pump. WHACK-MISS!!!

So after hitting that wall, I turned to continuing progress on the intake pipe and MAF sensor.
It now appears that the design I had roughed out for an air filter box isn’t going to work. There is so little space between the MAF sensor and the box that the original area in mind for the outlet out of the box won’t mesh with the angle of the intake. So that original box idea is probably out the window. May just have one of those conical filters hanging off in space until Plan-C manifests itself.
WHACK-MISS!!!

Rush, I wondered why you went with a rad. with the inlet over there, any reason? Also, how about a diesel sixty filter housing, I think that's what I use.
That’s the Mosley radiator. Thought it was supposed to be one of the best ones.🤷🏻‍♂️

I have an early FJ80 air filter housing that I was going to use and changed my mind.
May revisit that?
