100 amp MR2 alternator (1991 2.0L with powersteering). That year MR2 used an electric pump to run the powersteering. You have to change your pulley from the stock Supra alternator to the MR2 one...it's a tight fit, but bolts right up and the electrical connectors are identical.

if u have more Q'd that need to be answered Pm jdub as he has this setup.

hey go and do a write up, i always wanted to go this route, but i bought a new alternator, so yea.

 

[aye mate]

Wrong. Its actually bigger than the stock one, but bolts in. Same connectors and all, but it is a bigger unit.

It's a 100 amp alternator...and it is bigger than a stock Supra alternator.

John u notice that info in the second post i copied and pasted from your PM u sent to me when i had a question about it

haha!

 

[jdub]

Yep

 

[pimptrizkit]

jesus, costless wanted 135 w/ core and 185 with out..

im going to shop around abit, i do have a few others so i can get ride of the bad noise but would be nice having more amps...

that's the one i got.... and get it from autozone, lifetime warranty

also the 87-88 supra pulley will not work, and the pulley that comes with it won't work either... you have to use an 89+ pulley, i ended up ordering one from toyota.

what's the difference in the alt pulleys between 86.5 - 88 & 89+?

 

[jdub]

The diameter of the pulley shaft iirc.

Jim, this the reason your car was makin that noise??? Or is that not fixed yet. You never told me about this.

 

[pimptrizkit]

no not that i know of, but im going to change the alt today and see what noises i still hear.. that knock sounds like a knock to me..

pimp, you don't need a press, just a wratchet, and maybe some longer hose to lenghten that hose that goes from the valve cover to the block, as it will be kinda crushed once the alternator is bolted in... atleast mine was, if someone has a way around that i'll take some advice?...


thanx,
ross

now time to find one for under 150 bucks!

any one can confirm this? so if swaping to a pre 89, must use the 89+ pulley?

I'm pretty sure that's accurate. I recall a few members on SF had issues with the pulley (IIRC, one just had his machined to fit) while others had no probs swapping the pulleys.

 

[noel]

correct me if im wrong, but if ur going to upgrade the alternator to produce higher Amps...shouldnt the Alternator Wire be replace with something with a bigger gauge ???
