16 of the Most Interesting Engine Swaps We've Ever Seen

Stock engines are so boring.

Obvious engine swaps, like putting an LS V8 in a Nissan 240SX, are great, but we're not here to celebrate those. Instead, we're highlighting the wackiest, most ingenious, and wildest swaps we've written about over the last few years.

Twin-Hayabusa V8-Powered Lotus Elise

This Elise hillclimb car houses a V8 built by fusing two Hayabusa motorcycle four-cylinder engines together. As you can imagine, it's seriously good-sounding. Also, it's incredibly fast.

Toyota 2JZ-Swapped Rolls-Royce Phantom

Not getting enough excitement from your Phantom's quiet, 6.75-liter V12? Well, you're not alone. The owner of this Phantom had its original engine replaced with a hugely powerful, ultra-reliable 2JZ straight-six from the Toyota Supra. It's about as baller as a car can get.

Ferrari 458-Powered Toyota 86

Drifter Ryan Tureck had the wild V8 from a Ferrari 458 fit to a Toyota 86, which might be one of the most complicated engine swaps ever attempted. As you can imagine, it looks seriously cool in action.

<p>As if Volkswagen's famous Thing needed to be weirder, someone went and fit the turbocharged rotary engine from a third-generation Mazda RX-7 to this one. Why? We're not sure, <a href="http://quizcards.info/car-culture/buying-maintenance/news/a30256/turbo-rotary-volkswagen-thing/" target="_blank">but it's for sale and all sorts of rad</a>.</p>

LS3-Powered Porsche 911 GT3

We've seen 911s with V8 engine swaps in the past, but none as sacrilegious as this. This LS3-swapped 997-generation GT3 popped up on Craigslist last summer, and it's exactly as bothersome for purists as it sounds. Sure, that flat-six wail is gone, but who are we to say no to 525 horsepower?

800-HP 2JZ-Powered BMW E39 M5

The E39 M5 is famous for its fantastic-sounding, torquey 4.9-liter S62 V8 engine. But what happens when it blows up? Drop in an 800-horsepower supra engine, of course. The result is a super sedan with seemingly unlimited shove and a whole lot of whooshing noises.

<p>We love oddball engine swaps, and a Jeep Wrangler powered by the 4.0-liter V8 from a Lexus LS400 certainly qualifies as such.

<p>What's a Synergy V8? Glad you asked! It's a 356-horse, 2.4-liter V8 comprised of two Kawasaki Ninja four-cylinders joined to a common crankshaft. It only makes 200 lb-ft of torque, but it redlines at 11,600 rpm.
