I could only throw it with my finger about 1/8th of a revolution (it would move over like one blade) and now it'll spin almost half way around or so. I'm sure it gave me a good HP gain, when i floored it before the fan was louder than the motor.

e-fan conversion
I just finished my e-fan conversion! ....and I am stoked! 
I have 2003 sedan. I am in Texas - very damm hot! and as the outside temp climbs over 75-85-95-105... the performance is noticably affected.
Ambient Temp for me is a huuudge deal!!! I have always disliked the clutch-fan on this car - it was loud, and I always felt like it was sucking power on the low-end 
- based on the loud whoosing noise at low revs - even when it is supposed to disengaged (or be less-engaged) at higher revs, it was noticable.
So I went with DaveO's suggestion of the dual flex-a-lite 220's (12").
I will explain in more detail, but first; my comments on the results...
Holy-frickn-*****!!!
I was expecting some gains, but I am really, really happy with this mod - OMG - the difference is night and day! I am planning to get a dyno to validate the gains, but the difference is soooo noticable. The engine revs (and decelerates) quicker, it is quieter, and it seems to be running just fine - perhaps cooler (because I flushed the system and refilled with redline water wetter as well.) Increased torque is noticable and this is evident by the increase tire-squeal off the line. This is my #1 new favorite mod!!! I just want to keep driving it (been late for work the last 2 days beause I have to go find some squigglies to have fun on 
- it's like a totally different car!
Install notes;
Parts from Summit Racing Equipment (www.summitracing.com)
- flex-a-lite (dual) 220's (FLX-220)
- Variable speed controller (VSC)
- add-a-circuit (mini) (from auto-zone)
aprox $290 total parts cost.
- pretty easy install if you are mechanically minded.
Similar to a plenum install in terms of difficulty. Took me 5-7hrs with MANY interruptions, and some delays while I got answers on wiring issues (thanks Daveo).
I wired this with Daveo's guidance into the Aux e-fan power leads, so the unit is controlled by the ECU, and AC. Works like a champ!
Obviously removed the old clutch-fan, and also removed the Auxillary efan on the front of the radiator. After feeling the air-flow difference between the right and left dual-fan, Although you can run all 3 fans (duals and aux efan), I didn't feel there was any additional benefit in the 3rd (auxillary efan). Removing it helped free-up the air-flow to the radiator core.
I could not have done this succesfully without feedback from DaveO - many thanks Dave! Congrats and good luck with the new magazine (http://nissansportmag.com/)

Andy,
Oh MAN.... I was wanting to piggyback along with you and do mine at the same time. I gotta have! So how much beer and BBQ is it going to cost me to have you direct my fan upgrade?

I talked with DaveO and based on that conversation did his dual fan direct wire, sequenial conversion on the wifey's sedan last month. It produced very similar results to what you have described. The results according to her, and she's not a car person, are that the car's getting better gas mileage and has more passing power.
The conversion cost me $210 for the fans, another $20 for extra brackets, wire, tape, stainless hardware, a six pack and about 4 hours of my time. Had I done the VSC conversion the cost would increased by about $100, another 6 pack and 1 or 2 more hours time.

Great to hear this mod is working out so well for those in the hot states. I am still running with only the aux electric and no belt driven. Been that way since January and even when things hit 90F up here, the coolant temp got only up to 3/4 while sitting in 0-10 MPH traffic. No pinging, or any other adverse symptoms. I guess the belt driven must really only be needed in areas above that.

Just want to ask this before I forget. Has anyone tried just using the later model fans vs buying aftermarket? Seems like alot of the expense is tied up into the purchase of the fans themselves. I would think maybe a boneyard set of dual oem fans might work?
