As the title says, I just installed the SE-R fans in my 240, and I have to say that fitment was perfect (no trimming required)! This is by far the cheapest route if you want to switch to electric fans.
Things needed for this project:
1) Two SE-R fans
2) Two long 12-gauge wires (one for power and one for ground).
3) Whole lot of zip-ties.
4) 30-amp inline fuse.
5) Toggle switch to manually control when the fans come on.
In the process of wiring the ground wire and power wire to the battery:
I took one of the plugs of the SE-R fans to power both of them, and then used that one unit to head towards the switch:
30-amp fuse to be on the safe side:
How I zip-tied the two fans together, and then zip-tied them to the radiator fill-neck. Also note that all hoses and wires above the fans were zip-tied together to clean up the area a bit:
The bottom of the fans, unattached. I didn't feel the need to fastem them down as I didn't notice them moving around. I will try to fasten the bottom down later anyway:
Another part of the fan zip-tied to the radiator:
The toggle switch that powers the fans. This is the best I could do with figuring out where to place the switch:
How the engine bay looks after closing it all up:

The fans are from the B13 '91-'94 SE-Rs (my specialty). I don't remember the CFM of the SE-R fans, but I do remember that their flow rate is better than the Flexalites. A lot of S14 240 people go with Altima fans ('93-'97), which also are just as good as the SE-R ones, but they need to be trimmed to make them fit in an S13. I just chose the SE-R fans because that's what I had laying in my garage, and they just happened to fit perfectly without any trimming of any sort. So if you want another cheap option, these bad boys should be up there in the list of best bang-for-the-buck items in terms of mods.
And regarding the engine bay's cleanliness, man, driving in Ohio is a pain. Because this car is a DD car, I have to drive it in all sorts of weather. So all the shit from the salt to whatever else gets clogged up there. I just hope the bad rust won't come back, because I just had the car cleaned up (new paint job, rust removal etc.). I guess I'll have to live with it if the rust does come back. Oh well...
I changed the title of the thread, and I'll make this a sticky if you guys think this option is worth it.

im definately getting those fans today.

Nice post. Great plan to use Taurus fans or fans from other transverse domestics due to affordability/availability, but the big part is the wiring. Simple circuit with a switch. Good post.
I see you stole my avatar, Harris.
Yeah no offense but your wiring is a bit dodgy
You dont need to earth back to the battery terminal, just use a short wire to the car body. Also a high current relay with a low current switch is better than a single high current switch.
You should also be able to simply push a number of bolts through the radiator fins and use a wide washer on the other side to secure the fans
From an amateur electrician, I think you did a fine job with the wiring. Single switch is probably the most easy route to do. I have a question for Joel.. what kind of relay would you use, and what wires would you run to it?
I had them run in series. I should have mentioned this, but I'm not anywhere near close to good at wiring or electrical stuff (I'm very good at mechanical work). This is more than proven by the work that you see in the pics. So I think I did well enough work to make this setup functional. Somewhere down the line, I'll be enlisting the help of friends who are better at this than me.

Yes indeed! Being that you're in Australia, you can probably get the fans off of an NX (that's what I think they're called in Europe).

seems like a good plan, but i would probably just leave the toggle on at all times, unless it's not run off of the ignition on circuit, because if it's tapping power straight from the battery, or another terminal that is independant of the ignition, it would have to be turned on and off each time you start the car, but why would you not want to have a fan running? just when you're cruising at high speeds?

Yeah thats what Im talking about. The relay size depends on the current draw of the fans. If they work with the 30A fuse then a 30A relay is required.
This one is 20A so a bigger version is required, but it gives you an idea.
And for those that have limited electrical knowledge, terrans diagram shows the fans in parallel. Series would have the neg of the first fan attached to the positive of the second. Parallel would bring the speed of each fan up but also raise the total circuit current draw.
