    Performance mods

    Hello all, I'm new here and am excited to learn and implement alongside y'all. I was gifted a 94 zj with a 3" lift and 31's the motor and trans are stock with 220k+ on it. I'd like to do some performance upgrades on the engine and tranny...any ideas? It's the 4liter in-line 6.

    Thanks in advance.

    This is a late Welcome. Sry don't know how I missed ya.

    What are you looking to do with the vehicle? At 220k I'd be looking at a rebuild or engine swap. Not that your engine is bad but 220K is a tough time to start pushing a motor.
    If you go rebuild there are stroker kits or direct purchases. Though a 8 cylinder will give you more with room to grow.
