1986-1987 Turbo Regal & 1989 Turbo Trans Am - BRAND NEW CUSTOM-BUILT 200 amp ALTERNATOR Pre-tested with a Manufacturer's 2-Year Warranty

Some owners may have additional demands on the electrical system, which require a higher amp alternator. Our source is able to custom build brand new correct-looking 200 amp alternators. Because a 200 amp alternator puts a higher demand on the electrical system, it is critical that you run an additional 8-gauge wire or thicker wire from the (bat) terminal on the alternator to a 12-volt source (such as the starter or the battery.)This helps handle the additional load.

Working closely with a local source, we can assure quality control. Each alternator is hand assembled, pre-tested and comes with a Manufacturer's 2-Year Warranty. Most of the other alternators we have found use a generic pulley, which is not the correct diameter to maintain the proper tension on the serpentine belt. We have also found that most do not have a black pulley.

The stator section, which is sandwiched between the front and rear housing, is supposed to be black like the pulley. The stator on these new alternators are black, like the originals. The pulley itself has the proper diameter and grooves so the tensioner stays within the proper specs.

All of the other external parts (including the housing) and internal parts are brand new. The housing on this unit does not have any factory stampings.

Since each alternator is pre-tested, you can be assured it is producing a minimum of 200 amps. The proper amps and charging is a critical function to assure the electronics are getting the proper volts to the complete electrical system. Some of you may be running additional fuel pumps and this makes this even more important. No core is required, so you can retain the original alternator. It's always better to buy brand new versus used or rebuilt, especially if it's a car you plan to keep. NOTE - We sent one of the 200 amp custom-built alternators to be tested by Richard Clark. Over all the years prior to this, all the other alternators he has tested claiming to register 200 amps always fell short. He was impressed with this unit as it surpassed 200 amps and registered 238 amps! Remember, each of our units is pre-tested to be 200 amps, as advertised. An excellent replacement for any engine restoration.

ALTERNATOR UPDATE: Because of the success of this alternator, our supplier has exhausted his supply of the original factory pulleys. We recently had this pulley made to the exact size of the original. This is very critical on these cars, since the pulley size influences the rpms the alternator needs to turn. Many of the aftermarket alternators do NOT have the proper size pulley on them. The proper size pulley where the serpentine belt rides against is 2.405 inches. If you have a replacement alternator and are experiencing charging issues, you may want to check the diameter of the pulley. While other alternators may be cheaper, ours are 100% correct. During the years 1986-1987, these cars were one of only a few in the GM line up that had a 120 amp alternator, making it a critical part of the electrical system. Back then, most other GM alternators were rated at 90 amps or less.
