I am actually trying to accomplish your goal as we speak. Other than keeping IFS which is just plain ludacris!
Here my dreams:
3.3 head swap, ported/polished, 3 angle valves, mild cam to keep low-end torque.
Bored block, new pistons to match heads, full balance.
Massive tranny cooler(that's about all you can do).
4:1 t-case gears and divorced case as doubler.
Hardened axle shafts and 5.13 gears.
Big brake conversion w/ slotted/drilled rotors, dual piston calipers, high friction pads.
Long arms fabbed with custom knuckle ends, custom upper shock mounts inside the cab.
Batteries and heavy storage compartments near center under the cab.
Custom rock sliders, bumpers, and roof rack all tied together like an exo, custom front to rear skid plate.
Custom console to accept three shifters, custom gauge pods, five-point
harnesses, half-doors w/ plexi-glass, relocated ECU.
Silver metallic paint w/ flat black accents......
And she's done!
