LS-swapped bricks aren't necessarily a new thing, but those that make a nine second car look a little slow remain firmly in the extreme category. This one has a single turbo setup with a monstrous 1500 horsepower, all barely contained within the stock body of an old Volvo. The result is a vehicle powerful enough to effortlessly smoke massive drag slicks from a high-speed rolling start. Easing off the throttle long enough to allow the mad machine to hook up results in unholy straight-line acceleration... As one would assume from a car with big tires and a turbo where one oversized headlight used to be. Is it a sleeper? Regardless of how stock its body is, not by any conventional measure. But regardless of how fast it looks, this one turbo wagon will still shock you when it wakes up. Extreme Volvo Brick Speed Autopia LAThe engine is a 6.7L 408 LS truck block with forged internals, with a single Precision Pro Mod turbo bolted on the front. Besides being good for deep four-digit horsepower numbers, thanks to an appropriate suspension and tire setup, that engine pushes this old Volvo into the mid-8-second range on the quarter mile. Crossing the finish line at over 170 miles per hour. The stock Volvo 240 wagon might not have even been capable of topping out at half that speed. The interior is fully caged to NHRA spec, ensuring at least some modicum of safety when doing autobahn speeds in a piece of masonry. The rear suspension is a 4-link, cradling a Ford 9-inch rear end and suspended by QA1 Mod Series shocks. Power to Spare Autopia LAAs a built-out racecar with an NHRA cage, this old Volvo is surprisingly low-key from the outside. The tinted windows are a must, but if approaching from the back of the car at night, there's a real chance you wouldn't catch the enormous drag slicks tucked under the tubbed rear wheel wells. The car normally runs with a hood, and that also makes it seem much less extreme than with the full turbo V8 setup out in the wind. All that said, this car's factory left headlight is missing, and two shiny pipes protrude from the engine bay. Calling this Volvo a sleeper is a stretch. But even if you expect this bad brick to be fast, you probably weren't expecting Plaid-embarrassing levels of thrust.
