Yes you can, but there are a few things you'll need to know about the conversion and installation of an HO alternator before hand; specially how much more amperage that you'll need. The installation of an higher output alternator alone will not solve your needs for more "power in amperage" that you'll need to run whatever extra electrical loads on your car.

Some reading and researching will help to do it right before the car end up on the side of the freeway or interstate highway.up in flame/smoke. The least and first you can do is taking care of the wiring as follow (and the cheapest way):

When upgrading to an HO (Higher Output) alternator you should always install a larger wire between the alternator and battery. Even with a standard output alternator you will get better performance and life out of your alternator if you upgrade the main battery wiring. The original wire just isn't large enough for proper power transfer. If you are using your alternator to its maximum or upgrade to a higher output, you must increase the battery wire size. An alternator's ability to send the power it is making to the battery is directly related to the wire size and quality of connection between the alternator and battery. Also, a wire that is too small can cause the power to back up within the alternator, making it overheat, burn up and fail.

Another area that little is paid attention to is the ground. You must also improve the ground as well. A poor ground will hinder the alternators ability to send power to the battery and can burn an alternator up just as fast as an inadequate alternator to battery wire. Your ground may be fine when you first install your alternator but over time corrosion and resistance builds up in the ground connections. This is why it is best to run the ground directly from the rear of the alternator to the battery.

Here is another hing: When upgrading the wire between the alternator and battery, you do not need to rip out your old wiring for the new HD output alternator. You can piggy back a second wire between the alternator and battery. The main battery wire connected to the back of the alternator has power to it at all times, even when the vehicle is shut off. You connect this wire like normal then you run a second wire between the alternator and battery.

Remember: The power coming out of the alternator will treat the two wires as one, power follows the path of least resistance.

There are many places that you can obtain an HO (High Output) or HD (Heavy Duty) alternator. This is one of those. Contact them for more information. Do it right before harm come to your car electrical system. Go to this link: (I'm guessing you're living in CA)

You can try to search for other resources. Type ' Guide to high output alternator ' to your search engine and you'll get tons of links. Good luck finding more valuable information. HTH

Note: Some places even using your present old alternator and make it become an HO alternator. Ask them before buying one. The reason: You like the look of the old alternator (The housing/case) and won't worry about the installation.
