Question of the Day: Best recipient for supercharged GM V6?

The good old Buick V6 engine was built from 1961 through 2008 (including a decade of production by Kaiser-Jeep) and went into way too many General Motors vehicles to list here. In 1991, the supercharged version of the 3800 was introduced, with a Roots-style Eaton blower on top, and now you can find these engines in just about every junkyard in North America. The 3800 shares a bellhousing pattern with the also-made-by-the-zillions GM 60° V6 engine, which means that it will install (with varying levels of sledgehammer clearancing and/or axle mix-and-matching) into plenty of GM vehicles that never received the 3800 from the factory. That means one thing: engine swaps! An excellent example of this is the 1992 Chevrolet Lumina APV "Dustbuster" minivan, which is a fully caged high-performance road-racing machine that features a supercharged 3800 and 5-speed manual transmission under its long, vacuum-cleaner-snout-like hood. The RaceVan, in Springfield Monorail livery, will compete this weekend at the Michigan 24 Hours of LeMons race with Autobloggers Mike Austin, David Gluckman, and Alex Kierstein at the wheel. My personal choice for supercharged 3800 power, though, has to be the Cadillac Cimarron, preferably the not-so-sought-after Cimarron d'Oro Edition. Some bashing and welding and cutting and pasting and this lightweight Cavalier sibling could have well over double its original horsepower. So, what's your blown 3800 engine-swap choice?

The new Buick Regal looks like a Mazda, and we're totally cool with that

Yes, this undisguised Opel Insignia, which will be brought here as the next Buick Regal, looks a lot like a Mazda. You can see it in the grille and headlights, especially – in fact, if you look at one of the photos with tape blocking out the badge in the middle of the winged grille, you might think this is a new Mazda6. The thing is, Mazdas look pretty darn good, so no one's complaining. And when you look at the rest of the car, there's a fair amount of originality going on. Aside from the GM-generic taillights (they look like they could fit on a Chevy, right?) the lines and details are all pretty fresh, and there are some design elements pulled from Buick's gorgeous Avista concept. A sweeping roofline leads to some healthy shoulders at the back, creating a coupe-ish profile with a very abbreviated rear deck. This appears to be a hatchback model and not the four-door sedan, but the general look should carry over. This is definitely a big improvement over the somewhat bulbous current-generation Regal, which also started life out as an Insignia. The car shown here is the Insignia OPC model, with Brembo brakes, big wheels, side skirts, and a front end with big (likely fake) intakes. It will most likely translate to a Regal GS for our market, as is the case with the current OPC and GS. The new Regal/Insignia is expected to use the same platform as the new Buick LaCrosse, which is also shared by the Chevy Malibu and Impala. They should once again be available with front- or all-wheel drive and a choice of turbocharged four-cylinder engines. Rumor has the Opel versions debuting at the Geneva show March, and the Buick would likely follow, possibly in New York in April. View 13 Photos And then there's the wagon. All signs point to Buick finally bringing the most practical Insignia to our market as a Regal. We got wind of a focus group testing the idea, Buick has trademarked the name Regal Tour X. That version would likely go up against the Audi Allroad in the classy, slightly lifted all-wheel-drive wagon category, basically acting as an almost-crossover for people who want a wagon but won't admit it to themselves. The Insignia wagon caught here is also an OPC, and we think it looks even more handsome than the hatch-sedan shown above. The trim piece stretching from the base of the A-pillar all the way up and back down to the tail is a nice touch in profile view, although we're not so sure about how it terminates abruptly at the taillight.

1987 Buick Grand National was made to be Kevin Hart's 'Dark Knight'

The Meguiar's booth at the SEMA show isn't the only place comedian and actor Kevin Hart is combining cars and cinema, his "Michael Myers" 1969 Plymouth Road Runner brooding in the car care products pen, while his SpeedKore "Hellraiser" 1970 Dodge Charger also menaces. Hart bought a 1987 Buick GNX last year and put it on Instagram with the caption, "Sundays are perfect for old school drives…. If you know you know." Looks like old G-Bodies are perfect for restomod builds, too, which we all already knew, but this car isn't the GNX that featured on social media. This is the 1987 Buick Grand National, one step below the GNX and half the price at the time. It's nicknamed "Dark Knight" and it's one of the stars of the Magnaflow exhaust booth at SEMA. Going back to work with regular collaborators Dave Salvaggio of Salvaggio Design and Sean Smith, of course there's a lot involved in the overhaul. Still, we appreciate how the team stayed true to the ethos of the Grand National in ways that made the build more complicated than it already was. Take the engine. The original came with a 3.8-liter V6 wearing a single turbocharger to register an official output of 245 horsepower and 355 pound-feet of torque compared to the GNX's 276 hp and 320 lb-ft. Instead of swapping it for a V8, it's been replaced with the 3.6-liter twin-turbo V6 from the Cadillac CT4-V Blackwing. And instead of leaving both turbos on, the engine junkies plumbed a single turbo in a layout recalling the 1987 engine even as it cleans up the original Chutes 'n' Ladders mess of tubes. We didn't get an output rating for the setup. The Cadillac's twin-turbo mill makes 472 hp and 445 lb-ft. in the CT4-V Blackwing. We would bet Dark Knight's engine's pretty close to that with the single large turbo at the prow, plenty of juice for a car weighing 3,545 pounds. Exterior upgrades include a custom front fascia with a carbon fiber hood and splitter. The interior shows the same tasteful restraint, polished design and nicer materials draped over the stock 1980s layout. That shifter controls GM's 8L90 eight-speed automatic instead of the original four-speed auto.  Elsewhere, Salvaggio did the same here as with the Michael Myers Road Runner, creating a custom frame to increase rigidity and get the car closer to the ground on its 19-inch HRE wheels in the Buick's original weave look.
