Upgraded Alternators

[Jayhall]

I guess you could say Im seeing whos intrested in purchasing an upgraded 1JZ alternator. My Uncle owns an alternator shop and recently rebuilt, and upgraded my alternator to produce 160amps. My understanding is this is double the stock output. I can get as many of these made as I need, I just want to make sure there is and intrest in them before I put much more time into these.

Maybe post that up in the car audio section. I could go for a bump in alternator output but nothing that crazy.

I should mention, these can be made to order. If you only want 100, no problem, if you want 120, no worries. I got 160 becasue I could

anything negative about having more amps then the stock one would produce?

[Jayhall]

I asked my uncle the same thing and he said that even with the 160 amp that there wouldnt be any over charging issues.

160A peak output is fantastic, but what is the output @ idle compared to the OEM one?

[Jayhall]

still wating on those numbers. I never got a chance to test my stocker, because it was old and f'ed, but when I get to installing mine I'll get some numbers

interesting, i need an upgraded alternator for the 1jz
what the price range(160amps, 140amps, .etc.) do we send our core in to you or what not?
thx

I want more specs please! 160A at what rpm? And how much more output is it at idle? Thats what is going to matter the most!

And what kind of price are we talkin here?

folks kjeep in mind that nothing in this world is free. And particularly when it deals with physics.

More amps means a bigger stator field which means more resistance/drag on the motor. Unless running a stupid stereo system, the need for 130amp on these cars is negligible. By that I mean that we don't have none of the fancy shit the new cars have (heated seats, electronic everything etc).

I'd be interested in an upgrade for my 2JZ alternators, if you could do that? Price per amp would be good. Lots of electronics, but nothing competition-craz-worthy.

So depending on price, we're in for 2, 2JZ alternators.

I dont have alot of the specifics right now. Right now, Im just trying to see if there is an intrest so that I dont waste my time getting all the info together only to find out no one wants these.

There is definatly more resistance in the alternator, I can feel it when turning it by hand. That being said, its still very easy to turn by hand, nothing to it. The way they are being upgraded is with a new, more compact stator coil. Its designed to fit into the stock housing. There is also a extra, external resistor installed on the back of the alternaror.

As for price, Im not ready to say for sure %100 anything yet, but I **think** the dollar value is going to be the same across to board, whether you want 100 amps or 160, for an uprgraded 1J alternator rebuild. I will also be able to have a steady supply of the 92-94 SC alternators, which are a little larger, both size and amperage(105amps), but they are direct bolt in for a 1J.

As for the 7M, and 2J's, for a little more you could have a brand new alternator that has been upgraded, OR you could have a rebuilt and upgraded alternator for very close to the same price as the 1J rebuilds.

Im going to try an get mine on this weekend, then I will be able to get a few numbers to hopefully spark some more intrest

[mischief7m]

i would be very interested

I'm getting mine upgraded to 160 Amps within the week, I'll let ya'll know how it turns out.
