Within the next 2-3 months I want to do some engine work. I am planning on the 99+ intake manifold injectors, headers, and possibly cam. Those are just ideas and im not totally set on it. I was hoping you guys could give me advice on what to do and any certain brands for the upgrades or anything else I should do too. I have a 96 xj 4.0 automatic

Gee oh Dee

Skip the cam. Regear.

Also, bump up the entire exhaust diameter to 2.5" and get rid of the crush in the pipe by the front DS.

Port match the head.
Mild port & Polish.
Ceramic coated header to reduce underhood temp.
Flex-connector to reduce the likelyhood of cracking your exhaust header.
free-flowing exhaust.
Quality CAI.
Bore-out the throttle body below the butterfly.
Cap, rotor, plugs, and wires.

What should i regear to? It currently is running 35's with stock axles

Whar exactly does port match the head mean? (Sorry im new to all this) and i already got cap rotor plugs and wires. Any CAI you recommend?

4.56 or 4.88, 4.88 would probably be best. What rear axle do you have?

Go to grimmjeeper.com and use the gear calculator. You can do a side by side comparison of different options and determine what works best for you.

Chrysler 8.25. I was also wondering what you thought about lockers? Specifically ox mechanical lockers

SeriousOffroad

The only selectable locker available for the 8.25" is an ARB.

For your front there are many options. ARB, Eaton E-Lockers, even the OX.

Gee oh Dee

The new craze is e-lockers. Eaton makes a good one.

I run an ARB, and i love it. I have not had experience with OX.

Now if i was going to eventually regear and then get lockers, would it be worth it to do an axle swap first or just keep the stock axles?

Gee oh Dee

What size tire are you going to be running in the end?

35s should be ok if you beef up what you have, but much bigger and your better off swapping.

And don't put money into your axpes if you plan to part with them.
