2.5 or 4.0


Recommended Posts

Hello guys, I have 1987 2.5 2wd standard Jeep Comanche and the engine gave out on me, I was thinking of dropping a new engine  in it, my question Is what engine do y’all recommend or should I just stick to 2.5 L and would like to know what you guys have Under the hood. Thanks!

The 2.5L gives better gas mileage, but far less performance. However, as noted, replacing a 2.5L is far easier than doing a swap to a 4.0L. To change to a 4.0L you'll need a complete engine room wiring harness, a new ECU, a new radiator and radiator supports, a new transmission -- and probably a bunch of things I haven't thought of off the top of my head.
