1JZ Alternator Question

[JustinGotA1j]

The bearing in my alternator is pinging lately and I plan to replace it this week if possible. Just need to know if anyone knows of an alternator that is a bolt on replacement. I checked out the cross reference sheet and it says that the alternator for a 1992-94 SC300 part # 27060-46010 is the same. If anyone has any info regarding the trueness of this info or has any info that would be fantastic. Thanks.

yes its the same.. and larger capacity (90 amp vs 110 i think oc the SC)

It's the same. When i swapped I put the alternator from my 2JZGE on my 1JZGTE because it's higher amp and the SC300 has ALOT of electrical draw with all it's gadgets.

On a Soarer 1JZGTE, all the 2JZGE SC300 accessories bolt right up and you can get 2JZGE things dime a dozen here in Orlando with all the 1JZ sc swaps that are taking place.

Speaking of which, I need a new battery. It's only doing 11.8 volts when the car is off :aigo:

aristo alterntors seem to be teh same as the 1js as well... but not that it helps much, haha..

 

[Ric]

IS300 ones fit too.

the alternator doesn't need any modification so that the belt aligns properly...i had to get the pulley shaft on my 2jz power steering pump machined so that the belt lined up

yup drops right in.. no mods at all.. It does have a larger pulley, but My same belt worked fine...

Your so wrong. I just tried putting a MK4 TT alternator on my Aristo motor and need to know this asap.

ditto that right there + hugs (in the hetero way possible of course)

Your so wrong. I just tried putting a MK4 TT alternator on my Aristo motor and need to know this asap.

On my aristo engine, it had the same exact plug as the 1j, and sc300 alternator not the mkiv tt... I think it was out of a 93 or 94 aristo..

 

[Ric]

I put a 92 sc300 alt on a 2002 IS300. I also put a 1993 1jzgte soarer alt on a 1993 supra tt. All worked just fine.

 

[tissimo]

interesting.. I've heard the mkivs have square plugs or whatever rather then the 1j's round...

 

[Ric]

Most 2JZGE's have round.. but for some reason my friend's TT had a round also.

... but not that it helps much, haha..

My bad I was refering to this part of your sentence . . . kinda saying thank you to you as well as Supramania in general. Hug? . . .

Hey guys,

I got the SC300 alternator and I don't think it's the right one for the Aristo.

Can someone just verify for me which style connector it is for the Aristo 2J . . . may be walk out to the car and check.

Excuse the kindergarten drawing, my digi cam is MIA. On the LEFT is the round style connector from the SC300 alternator. On the right is what I believe is my Aristo harness has .. . I had to dig up/figure out what is was out of my 50 lbs of Aristo harnesses I remember have this harness on the motor at some point. I think it wraps around the back of the motor from the fuse box to the alternator.

 

[Ric]

It's hit or miss my friend, there is no set standard for what car has what.

 

[tissimo]

My aristo harness has the left like my 1j harness.. mine was an ealier aristo, maybe the later years they changed it I guess.. is the right the mkiv?

 

[Ric]

Left is supposed to be MKIV, but my friends 94 TT has the round one.

 

[Jacob]

It seems like hit or miss for sure. I am almost certain that mine is the one on the right. I wish I hadn't given them my stinkin core before I got the new one.

I really hate to go back for a third time. One good thing about autozone is that they have pics of the alternators so this time I will be sure.

Thanks guys, this forum seems to have a ton of helpful/sharing people.

I'm bringing this back, if it's cool.

I have a 1jz installed into an mx83 cressida and have been having alternator problems. I just checked the plug on my alternator and it appears to be the one drawn on the right; three pins, all flat.

From what i understand, the sc300 uses the one on the left. does this mean the sc300 alternator is not a plug and play unit for me?

Any suggestions as to what i can do b/c it's my DD.

Thanks
