Killed a few minutes in the garage tonight, and fortunately I think the radiator conversation is moot now. I like the idea of e-fans, but I went into it knowing it was just going to add complexity and cost. The lack of good options makes it tough to pursue further.
The original plan was to just move the radiator over to the passenger side about 1/2" and keep everything otherwise stock. At the time, it was hard to tell if that would actually work. That's why getting those engine supports and chassis rail brace in was a big milestone, so I could get confirmation. Looks like I only need to move it 3/8" so I was very close, and things are still pretty tight, but it looks doable. Fan blades clear the shroud, which is probably the most important part.
Took a torch to the shroud to make some clearance. In hindsight, I probably should've just used the heat gun or boiling water. Looks like $h!t, and the plastic melted through a little, but I really just needed to get quick fitment confirmation.
I may just cut an opening, or rivet in an ABS patch, but this going to work. I have some points where plastic will rub on metal, but I can trim that or live with it.
Regardless of the path I was going to take here, the radiator was going to be replaced. It's actually nice to not have to put something else in. The truck will already be a Frankenstein by the time the project's done. I'm having to closely track where all the parts come from...Land Rover, GM, Jeep, Toyota, and even other Nissans. In this case, I only wish there was some sort of radiator upgrade for the R50, but staying stock saves a few bucks and moving the mounts shouldn't be too difficult.
