Just call your local parts store and ask them to compare the amps for ya.

Check out ebaymotors. You can get a 130A alternator for a 86-92 Supra for about $100-$130 shipped.

I also gotten a MR2 alternator from my JDM motor but I never used it because I already had a new one.

I'm running it b/c I had the same problem running FAL's. It's a direct bolt up, and the application is a '91 MR2 turbo w/ p/s. 27060-74180-84 12v 100a .

The only thing I had to change over was the pulley and have the i.d. (of the pulley) bored out by a machine shop.

I'm running the mr2 alt. as well. Use a pulley from an '89+ and you should be golden, Ryan. The stock Soup plug fits np. If you have any probs locating one, I can get you a rebuilt one in Bby. for $140 cash from "buddy".

 

[NashMan]

yae all did some diggin at work and this will work no prob

plus i goig to get the 100 amp one

all did you knwo they had 3 diffetn alts over teh year's of the secound gen mr2

only yhe 100 amp will work with the 89's cause of the pullie spindle

the other will work on the 88's and lower

I just ordered the 130amp alternator from Egay.
I imagine it is simply a rewound, stock alternator, or maybe they use a different type of regulator or IC's. I had planned on doing the MR2 alternator, but didn't want to deal with squeezing that oversize badboy in there with the fuel plumbing I have.

 

[NashMan]

hummmm that is did not know it alot bigger ?

 

[supraguy@aol]

No, just a little bigger, but I've got an FPR line right behind it, and I didn't want things to squeezed together back there. I read that it'll fit with no real mods at all.

 

[NashMan]

i think i may just get one 280 my cost for new one thou witch is not bad

 

[supraguy@aol]

Check Rockauto.com
You can get it for $135

i got my mr2 alternator from autozone, lifetime warranty pulley did not fit .... had to order a 89+_pulley from toyota since my old unit was for <=88

So after you install the bigger alt how much of the HP you "freed up" is left?

 

[Poodles]

IJ: be nice, I like e-fans too....but mine is nice and cool with a properly working stock fan now...

but hey, he can have a bigger stereo now...

 

[IJ.]

I was being "nice"

If the stock Alt isn't keeping up think of the drag then going to a larger capacity Alt = even more parasitic loss so in the end just how much of that "free power" is left to move the car?

 

[Poodles]

well, the e-fans aren't on all the time (if properly set up)...

 

[IJ.]

And at the times the e-fans would be off the stock 10 blade would be freewheeling or windmilling on it's clutch....

 

[Poodles]

this discussion could go on and on...

but I will make a comment that the stock alternator on our cars ia a bit...small for the amount of electronic equipment...

 

[IJ.]

I run an NA Alt and NEVER have an issue and haven't for the 10 years I've owned the car

 

[7MGTEsup]

Never understood why people fit electric fans when there is a perfectly good mechanical one fitted from stock. Must be an astehtics thing:dunno:
