Electric fans

fulljapan · 08-10-2007, 04:05 PM

I have noticed that many supra owners change their fans for electric ones... Is there a reason in particular that is directly related to supras?

clutch type fans, not only in supra's, rob power and do not cool effeciently. they are also loud and take up alot of space in your engine bay making it harder to work on your car. i plan on doing a elec fan swap myself. from what i understand there are many cheap options (dual ecplise/talon fans, ford contour fans). most of my friends drive 240's and they have done an electric conversion. a little more free revving and lower temps. the dsm fans are about $20 and your gonna need wiring and i would reccomend an in-cabin switch which is $10 at autozone. $30 for lower temps, more power and a cleaner engine bay....sign me up!

Do some 'searches on this forum for info on electric fan conversions. You will want more than one electric fan.

Mine came with the 2 little ones, so I added a 12" diameter electric one that flows 3000 cfm. It was $100 from Summit. Others have used used ones from the boneyard of of other brand cars. 2 fan setups.

Just make sure the amp draw is not too much for the alternator.

from what i understand you can swap a mkii mr2 turbo alt into a 7mgte with little/no fabrication.

way better alternator...

I can't say its 'way better', as mine is still original with 175k....and I've seen many MKIII's still running originals.

Automatic trans MKIII came with an 80amp, while the manuals came with 70amp.

All the ones I could find at the local parts stores for the MR2 are 70amp. Most are external voltage regulators.

I think you'd be better off using the 80amp MKIII for the automatic trans model.

Any way, what I meant about fan amps is...my 3k cfm fan draws 8amps. I was looking at some other brands, and they draw 10,15,20, or 30amps, and one high volume fan claimed 50amp draw. That's just crazy.
