Compatible Alternator's

Postby g1_teg_lover » April 4th, 2013, 8:24 am

Anyone know if any other model honda's alternator will fit our tegs. Mine's about had it, and most parts places here are only carrying remanufactured (which is what i put in 3 years ago, and is now starting to have issues charging). I know the stock alternator is on the weak end to start with (55A @ 1800 rpm) and figured that it might be possible to get the alternator from another honda (preferably something 80A or higher).

After looking for hours trying to see if there was a way to use another model's alternator, I've managed to find that the 91-93 accord alternator looks to be a close match (can't really tell the difference in size from pictures). The Accord alternator puts out about 80A @ 1800rpm (45% increase). I also happened to come across a site (click here)which sells a 220A alternator (220A @ 1800rpm, 135A @ 800rpm) which fits our cars. That's a 300% increase in output current when compared to the original, but costs $549.00, way more then i'd be willing to pay :lol:

Most auto parts stores only carry Beck-Arnley rebuilts and I've had decent luck with them. Unfortunately, they're only compatibility is just for g1tegs. can't find anything else that will claim to fit. :ugeek:

The 55-60A OEM range alternators are fine. Unless you are running some type of extreme audio setup or anything else that really drains electricity, you will not gain any improvement.

The 86-87 models do share some compatibility with alternators from certain 84-87 Civic models. Not sure if the 88-89 shares any commonality with other Honda alternators. As far as I know the plugs differ. You might be able to find one from a later model Civic or Accord that bolts up but the plug would have to be modified.

The compatibility listing only show the first gen integra as the only vehicle, Honda or otherwise. Looks like they stuck it to us. :x

My stereo system isn't extreme at all, and the stock alternator even after replacing it 3 years ago could not handle it very well, unless the engine was rev'd to about 3000 rpm and held there. Currently running a 1000w amplifier (200w per channel) which is run off the battery with 2Ga wire through a 40A relay (to make sure there's no power draw when the car isn't running), still have the lights dim out badly at low volume with the brakes being pressed. Can't turn the stereo system up without having people think i'm flashing my lights at them :lol: .

Before you install the new alternator check grounds, wiring, etc... throughout your entire electrical system. If you go with another stock remanufactured unit, test it properly before installation. I've seen so called rebuilt units that weren't exactly rebuilt properly.

Higher amperage alternator options are limited for the 88-89. Counter-clockwise rotation and plug type 294 is used. Problem is finding something that will bolt up. No idea if the stock alternator housing would allow it but it is sometimes possible to disassemble a better alternator and reassemble it in the old housing. The 90-93 Accord alternator has a different bolt pattern but if you are skilled the internals might fit in the 88-89 Integra housing. I have seen this done but it is very difficult and often could require custom fabrication.

How do you test a remanufactured unit before installing it? This would end up being the 2nd reman. unit purchased (first one was from Beck-Arnley, lasted 3 years) and 4th alternator total that i've installed (2 Junkyard pulls that have both lasted about 2 years each).

A place like NAPA or Autozone will test it for free.

Also you might want to look into finding a new alternator if you can and the price is right.
Instead of another reman, I went with a brand new Bosch unit. That was 11 years ago and its still going strong today.

Downgrade your sound system.
Why do you need it to be so loud.
The G1teg is not a good base for a loud car stereo.

It's not kept really loud, I just like to be able to feel bass in my music. That and to show those people, the ones you can hear (and feel) 3 cars back at stoplights, a thing or two. Usually get behind them and give them a good taste of what i'm listening to (something like this or this). Not to mention, I really enjoy feeling my music (keeps me awake on long trips).

Hey now, I only do that at lights if someone is doing it first. I normally keep my stereo where it's not going to disturb others :lol:

I was cleaning out my shed today, and managed to come across an alternator that I had replaced from a friends grand-am for him. In the same box, I found an alternator from my teg (one of the junkyard pulled ones). I'd have to take a good few measurements on the mounting holes, but they looked to be about the same size (eyeballing it).

Then it's just a matter of figuring out what pins go to what and changing out the end (or making an adapter cable) to hook it up.

Ok, got some pictures of the two alternators (the one for the teg on the left, GM one on the right).

From the looks, the two are almost the same size, with the difference being the Honda one has one mount that's slightly larger and the pinouts. I'll have to see if I can find a part number on the GM alternator, but I do believe that it is a CS-130, which I've seen swapped into many other vehicles (Toyota's, Mazda RX-7s, etc.). I've still yet to take full measurements, need to get my digital calipers back from a friend i lent them to before going to the next step of seeing how hard it would be to fit under the hood.

I doubt the GM alternator will work running counterclockwise.

Alternators aren't direction specific as they create AC current that is then converted to DC via the rectifier. As long as there's a creation of the magnetic field, it will produce current, which is why some people use alternators to create wind turbines (it works, some small mods are usually needed). The only thing that the direction has an effect on with the GM one is the cooling fan on the pulley. That's a simple fix, as I have a place that does sell the pulley replacement for CCW rotation (so the fins are properly cooling).

My alternator is also done :/ do you guys think it's a bad idea to get mine rebuilt ? I have a friend who his uncles ownes a shop and they rebuild alternators and axels and starters. They rebuilt a lot of things for shops like O'Reillys auto parts Napa pep boys Ect here in my town . So what do you guys think
