Mechman high output alternators · Authorized dealer
Two very different Regals share this page. The 1986-1987 3.8L Turbo cars are collector muscle, often restomodded with modern fuel and cooling upgrades. The 1999-2004 3.8L sedans are front-drive daily drivers that tend to get an amp and a sub. Mechman builds a Buick Regal high output alternator for both, in outputs from 240 to 400 Amp, so start by finding your year.
Owners of the 1986-1987 turbo cars, the Grand National era, rarely leave the electrical system alone. Bigger fuel pumps, electric fan conversions, boost and wideband gauges, and a modern stereo all add load the original charging setup was never planned around. A Buick Regal high output alternator from the turbo-era family handles that in 250, 370 or 400 Amp form, with finish options including black, machined and natural. Many owners also want the engine bay to look right, which is where the finish choice matters.
That family includes billet housings, machined from solid aluminum for a crisp, show-ready look, alongside standard cast housings that keep a factory-style appearance. These turbo-era listings are marked custom fitment, so confirm your setup with our team before ordering.
Later Regals use an entirely different alternator series, the one built for early front-wheel-drive GM V6 cars. These sedans are commuters first, so the usual build is one amplifier and a trunk subwoofer. Pick 240 Amp for that, or 320 Amp if a second amp is coming. Some of these sedans also carry a dash camera, a remote starter or brighter lighting, which adds to the steady load. Each series belongs to its own years, and that split is the first thing to check with the vehicle finder at the top of the page.
Both families are Mechman high output alternators. Whichever Regal you drive, run a Big 3 wiring kit so a Buick Regal high output alternator can deliver current cleanly. Restomod installs may also call for parts from our alternator harnesses and regulators. Park Avenue owners have their own page, and so do LeSabre drivers.
