If i ever install i cam i'll change them out to a 47psi injector. There are a ton of write ups online about it. The injectors arent much money if you shop around on ebay. I also suggest changing the regulator when doing this.
This plus new accel coil with plugs gapped to .040 ( might gap them a little more) was a great way to smooth out the engine and get more mpg and will only better any other mod i do.

Higher flow. Also stock jeep injectors (pre96 i believe) all have only one hole where as the bosch ford injectors have 4. That means better air/fuel mixture. Just finished and did a quick test drive. Better bottom to mid acceleration, better mpg( at least thats what the overhead says), and maybe 2-3 more hp(not really a notice able difference), and runs smoother.

Would there be an advantage to make that mod on a 2000?

97 and up XJs have the fuel pressure regulator as part of the fuel pump assembly in the tank so the upgrade doesn't quite work the same. I don't think there are as many options for this approach but you could probably install higher flow injectors anyway.
However, 99+ has EV6 connectors and will take a direct swap with 784 injectors or the KJ Liberty ones. Do some looking around in the Modified Tech thread, there are about a billion threads on injector upgrades.

Last night busted the lower arm off of the axle. Had to limp out if my wheeling area and home. Now I'm wondering if it isn't time to fab up a long arm setup PR try to weld it back on.

Hmm must be the angle, then. I thought about D44 but the diff cover looks way too dome-like and not enough apple-like in the piccy
Wha... what happened to your rear brakes? Where's all the rust???
