Ls Engine Swap

8 of 23
The aluminum 6.2L LS3 V-8 is a compact package that produces over 400 horsepower and gobs of torque off idle. The 6.2L Motech swap includes their heavy-duty aluminum radiator. They wanted me to mention their air-intake tubes and PDC are better looking now, as this was the first LS3 JK they had done. It looks good to us. As you can see, the installation looks OE. Motech utilizes the JK’s OE alternator, power steering pump, AC compressor, and cooling fan/shroud assembly. While the installation looks OE, it works much better than OE, with instant throttle response and seamless power to the ground.
