Hi All,

I purchased a 1999 JGC limited with the 4.7 for cheap. I determined the engine needs to be rebuilt due to lack of maintenance and a broken head where the timing guide bolts in. I have lots of pics and will be posting my journey here as well as asking for feedback. Mainly, I will be looking for things to do "while I'm in there..."

I'm not looking for crazy HP since this is going to be for my mom. She loves Grand Cherokees! I've been wrenching for quite a while but am new to the 4.7. One upgrade I've decided on so far is the air intake manifold from a 2002. I found one used on eBay. I plan to send it out to have it "refurbished." Another upgrade will be injectors. I found ones to use from a different thread on here. It's the one with the bulletin that came out. I will try to find the part number. No pics on this post but they will be arriving shortly.

Here are some things I'm wondering about currently:
Exhaust headers. Any good, worthwhile ones to purchase?

Is there an upgrade for the throttle body? Just run the original?

Programming? Anything I should consider or need?

Thanks for following along if you decide to!

PS. I have a 1996 XJ with the 4.0 and 125K miles that runs great! The A/C still works and I haven't had to touch it.
