They're pretty easy to find actually. I've posted links to other manufacturers and shops in the past, you might find them if you search the forum but it's nothing special.

As for the fan shroud, Perma Cool, Flex-a-lite and other manufacturers make extensions which will move the fan forward into the proper location for the stock radiator shroud.

I stumbled across some of those yesterday, but I was unsure about them because I'm not sure what fitment I need. I guess I expecting one to be specified for a mk3 Supra. I just measured the fan I currently have on my car and it's 14" diameter and 1.5" wide, but it mounts directly on the radiator since it's electric. Also, I'm pretty sure the radiator that's on there isn't the original, although it may still be OEM, not sure. Will this affect anything?

Also, I'm not sure what clutch to look for either. From what I've heard, a factory fan clutch won't work with these flex fans right? Are the clutches specific to each fan model?

And thanks for your advice about the extensions. I guess the size of the extension I need will vary depending on which fan I decide to go with, but how will I know how close the fan needs to be? I don't have the factory shroud to use as a guide.

IT's an easy enough equation. You want to measure from the innermost side of the radiator to the mount on the water pump. Now deduct one inch. That's the maximum you can go including both fan, clutch and spacer. Manufacturers and shops should list the dimensions for most of the products online.

As for the fan diameter, you'll need someone to measure and provide you with the diameter of the fan shroud's primary opening at its NARROWEST POINT. The fan shroud is a two piece unit and you should get the measurement with the second lower piece installed. Again deduct one inch and that would be the maximum fan diameter I would use... I might be inclined to go just a little smaller yet.

All in all not too difficult of a project, just need the one measurement from the shroud which you don't yet have and you should be good to go.

I had one of those flex fans with out a clutch and it was super loud and made a winning sound also felt like it was stealing a lot of power from the motor and cause the belt to slip. so I would use a clutch. I switched to dual electric fans with its own thermo switch set at 200 Plus a 2 row radiator. Also i upgraded my alt to a 140amp to help run the fans. Here is every thing needed to go back to stock not cheap.

Yeah, you should never run a mechanical fan without a clutch, factory or otherwise. You're lucky it didn't come through your hood.

Yeah, after doing some more research I realized going back to stock is going to be more expensive than I anticipated. If I'm going to spend that much, I guess I might as well get a good quality after market one. Plus I wasn't really too excited about the large fan shroud taking up space...

How do those fan controllers work exactly? Do they measure air temp or coolant temp? Because the sensor that's on my car now for the fan is pressed right up against the radiator so it just measures air temp.

I like the flex-a-lites, again because of the flexing blades, but I also found this one and haven't quite made of my mind yet:

Doesn't seem like to bad of a deal since it includes a new aluminum radiator as well. Quality is my only worry there...

I've also seen some Godspeed radiators that seem to be a pretty good deal. Any input on those?

This is what I got

http://item.mobileweb.ebay.com/viewi...id=58715271968

This is what I use to control them uses coolant temp. To turn on/off it been 100+ degrees by me and my car is running fine same temp and everything.
