Somebody Dropped a K20 In a Mercedes C240

There's nothing inherently novel about a K20 swap. The engine, with its lightweight, high redline, and unbeatable reliability, is a great way to get reliable, engaging performance for a decent price. What's wild, though, is doing a K20 swap on a Mercedes C240.

We're used to seeing these kind of swaps in cars that have renowned dynamics but weak, fragile, rare, or uninteresting factory engines. A Fiat X1/9, with its barebones simplicity and puny OEM powertrain, is a great example. An E30 BMW 3 Series is another, only because even its relatively stout family of powertrains are all getting quite old. But a Mercedes C320 is a not particularly well-followed small executive sedan, something that doesn't exactly scream "performance drivetrain swap."
