Over the years we’ve written hundreds of articles on LS-swapped cars and the enthusiasts that own them, and we don’t plan on changing that formula anytime soon. But with time comes experience, and we’ve seen our fair share of crazy, outlandish and even downright insane LS-swapped cars.

It’s hard to pick just three to showcase here today, but we’ve decided to reflect on a trio of LS-powered cars we’ve written about in the past in this segment. The criteria for today’s selection is – diversity, rarity and feasibility – and we think these three GM-hearted vehicles just might fit the bill. Check out what’s on the docket below.

Brutal Twin Turbocharged 5.3-liter swapped Lexus IS300

We first shared this four-digit-horsepower Lexus IS300 more than two years ago – and we admit we still have a sweet spot for this car – but can you blame us? It’s a rear-wheel-drive, four-door sedan powered by a twin-turbocharged all-aluminum 5.3-liter V8. The venerable IS300 now makes 1,200 horsepower at the rear wheels on corn and bangs gears with a TREMEC TR-6060 six-speed manual transmission all the way to mid 8s in the quarter-mile, and that’s on a modified IRS, too.

Describing this Lexus as impressive is quite an understatement, but it will have to do for now. Though the owner commented that he drives his highly-modified IS300 to the occasional Cars and Coffee event, the car doesn’t see a whole lot of street time; but that might be a good thing for some of us who don’t want to be embarrassed by taking a beat-down from a four-door sedan.

LS3-Powered Lamborghini Diablo

We’ve said in the past that browsing websites like eBay and others can sometimes yield some pretty interesting results, and this LS3-powered Lamborghini Diablo is no exception. Yes, folks, this is the real deal; an actual Lamborghini Diablo powered by a 6.2-liter LS3 V8 sourced from a C6 Corvette. The car was listed a few years back and has presumably sold by now, but that doesn’t make its story any less interesting.

According to the original listing, this 1995 Diablo had suffered an engine fire previously and was sold without a drivetrain to the owner at the time. “After considering powertrain options, the best to suit the job was a C6 Corvette LS3 with a Porsche 911, five-speed (G50) transaxle. I wanted the car to match or exceed factory power ratings and a mildly modified LS3 would certainly do that,” the owner at the time commented.

Twin Turbocharged, LS Swapped NB Miata

You’re probably noticing a trend here, and that’s LS-powered cars with a pair of Satan’s hairdryers attached. Well, this NB Miata is no different. This Japanese-produced two-door convertible features a 5.7-liter LS1 V8 below the centerline of its fenders, but those massive Garrett turbochargers refuse to be confined under any hood.

We’re told that, even with boost-creep issues, the car still managed to make more than 650 horsepower at the rear wheels. Of course, that’s no challenging task for an LS engine, but impressive nonetheless in a car that more than likely doesn’t weigh a hair off 2,500 pounds.
