This LS-swapped Jeep XJ on Facebook Marketplace packs a turbocharged 5.3L and a build sheet that hits hard. Furthermore, at $14,000 OBO, it brings serious performance for the price. If you want a Cherokee that can embarrass muscle cars on the street and still crawl a trail on the weekend, this one checks both boxes. The seller has a clean title in hand and documentation for the parts, so at least the paper trail is solid.
Under The Hood
The LS-swapped Jeep XJ runs an ON3 turbo and intercooler breathing through custom headers. The rotating assembly features forged CP Carrillo H-beam rods and pistons. Additionally, a Texas Speed stage three turbo cam pairs with upgraded valves and dual valve springs up top. A two-step launch control rounds out the ignition setup, and a Magnafuel 750 external fuel pump handles fuel delivery. Previously, the builder tuned this Jeep on E85, and it made 780 horsepower. It currently runs on pump gas, though the seller does not have current dyno numbers on hand.
The Drivetrain
Builders rated the TH-400 automatic transmission to 1,000 horsepower. It features a forged drum, forged shafts, a 2,900-rpm stall converter, and a manual valve body. Additionally, a 241C transfer case manages four-wheel-drive duties. Out back, the LS-swapped Jeep XJ uses a built Ford 8.8 rear end loaded with chromoly axle shafts, upgraded differential clutch packs, and 3.73 gears.
Suspension And Tires
A Skyjacker 8.5-inch long-arm lift kit supports the chassis. Brand new 35×12.50R15 BF Goodrich KM3 mud-terrains are mounted on 15×14 wheels. The seller describes the interior as being in good shape, with brand-new carpet throughout. Overall, this XJ covers a lot of ground, both literally and figuratively. Consequently, $14,000 looks reasonable for everything the build includes. The seller also states that no trades will be considered.
At the end of the day, this thing makes absolutely no sense–which is exactly why it makes perfect sense. A 780-horsepower, turbo LS-swapped Jeep on 35s isn’t supposed to exist in a balanced, reasonable world. But here we are. It’s equal parts bad decision, brilliant execution, and “let’s see what happens” energy.
Is it practical or refined? Not at all. Will it scare you a little every time you get into boost? Almost guaranteed! For the money, you’re getting a vehicle that can gap muscle cars, climb a trail, and probably make your neighbors question your life choices, all before lunch. If that doesn’t sound like a good time, you might be in the wrong hobby!
