I have a 1980 928S Euro with a bad alternator. Has anyone got replaced the early style alternator with one from a later model. If I made this change would I still have to have the air vent system like the one on my 80, Toofer

 

Yes do a search and convert to Delco. 14.5 V yea!

 

Or you can have it rebuilt with a 160a or 190a kit.

 

Or you could just get the broken one rebuilt for a fraction of the price.

 

I put on a Delco style last week. All you need it the alternator and a pigtail connector (search this forum for the word "Painless" - that's the brand name of the connector). I can now use my headlights again.

 

Wow, I can`t remember when I got so many answers to my question and none of them are worth the time invested to type them.

 

Later serpentine models do have the plastic housing on the back to force air in. I think you would just need to change the pulley (easy to do with an impact gun).

I'm also a fan of the Delco CS-130 alternator though. I've converted my car, and just did another local guy's car this past weekend. They are $120 including the core charge and are 105 amp.

 

Seeing that even the later model alternators have a hard time supporting modern electronics and stereos, A larger output rebuild kit has a lot to do with anyone's quest to replace an alternator. It's an affordable option many don't think about. An option that doesn't require adaptors. If someone gives you advice you don't feel fits your question, ignore it, don't razz folks for trying to help.

Also recommending the Delco is a great alternative for replacing a bad early alternator. It was sound advice given. Again something someone with 90 post to their name might not have thought about.

Even a stock rebuild kit would have been an easier option to replacing the early alternator with a later year model..unless you wanted more output as well, which brings you back to the Delco and Larger rebuild kits.

The later alternator is designed for a different turn ratio than the early models. Just changing the pully from the ribbed belt to a V-belt will under drive the alternator putting out less power.

Sorry but your statement was bad form and disrespectful to those trying to help out.

 

Read from post #15 onwards in this thread.
I did exactly what you are asking about - installed a '82 -'84 alternator, reference as a AL325 alternator. I had to buy the matching rear plastic duct from one of our suppliers .... but it fit the wiring harness OK, and with a modern regulator, does ~14.5V. I did not have to pull the pod to change the resistor to promote " self-excitation" ( yeah, that's an alternator term ) - works great.

 

Toofer, sorry for a short answer but the Paris Rome alternator is crap, Bosch is crap. Even if you have a Bosch just laying around its not worth the effort to bolt in.
$100.00 from Autozone (warranty forever)
Your engine will start easier, idle smoother, lights will be brighter, amps will pound harder.

 

Hmmm... I thought several of us were trying to offer you ideas you may not have considered.


F.U. then.

Note to self - no more help for toofer.

 

Pretty much.

 

Yeah. I have a good, cheap, idea. Keeping it to myself.

 

 

Who you calling a kitten ****?
I look more like this.
