We can hardly wait to get our hands on the incoming Cadillac CT6 sedan, which seems set to replace the slow selling, front-wheel-drive-based XTS. While it’s tough to make a case to keep the soon-to-be-irrelevant Epsilon II-based sedan, we are sure to miss its available twin-turbo 3.6L LF3 V6 in the XTS Vsport model, which is good for a heady 410 hp and 369 lb-ft of torque.
Thankfully, the folks at Preownedengines.com have realized its potential and now you can buy your own used LF3 engine through them, without having to break the bank on a used XTS. (Yes, you can still find the LF3 in the Cadillac CTS Vsport in longitudinal form, but that’ll cost you even more.)
Introduced in 2013, the transverse 60-degree six-cylinder can easily fit into any Epsilon II-based vehicle, like a ninth or tenth-gen Chevrolet Impala or Buick LaCrosse, and you can likely shoehorn it into many other transverse vehicle applications with a bit more wrenching and wiggling.
The lightweight block, made from aluminum, offers significant weight advantages over a cast-iron block and you can fully expect between 17 and 27 mpg, according to the retailer.
The company also says that the engine has been tested with the 6T70 and 6T75 automatic transmissions, which means you could theoretically turn a Pontiac G6 GTP (the only G6 with the 6T70) into a 410 hp, white-knuckle monster.
The engine applications are nearly endless– all you need is the LF3.
