I'm considering replacing my injectors, installing roller rockers, valves and anything else that would make my 4.0 run a little smoother. Is there anyone that has done stuff like this or knows anything else that can help the efficiency of my Jeep. I want it to be powerful but it's my daily driver and I'm a college student so I can't spend too much money doing it.

good luck on roller rockers... i believe they are a couple grand for a head thats predone. but you can find them for like 150... per pair.

Cat-back exhaust, header, cold air intake, 63mm TB, hotter ignition coil for bigger spark plug gaps, SN high efficiency oil. Horse power isn't cheap but it's worth it. I just put a header on my 89 and have felt an up in power (not much) and MUCH better MPGs.

What headers would you guys recommend? Stainless or ceramic coated?

austinjoe13

I think it's mostly preference. If you're willing to pay $400+ I would thing either would do.

But for $160 you can get a stainless "factory replacement" which is the same design as the torque tube type. Lots of people recommend these too.

What kind did you get. you have got me thinking about doing headers next ahaha

or you can go on summit and get them for $325 for the set. and it does not cost a couple grand to get a head redone, thats for an all aluminum head. to get it redone might cost $500 with new springs and original valves and getting completely cleaned.

I got the APN initially but it doesn't fit renix set ups so I got a pacesetter. I love it!

GRANDLICH

that good news!

thank you.

Is it difficult to DIY? Not exactly trying to spend 500 bucks for something I've seen done rather easily in JP mag.

It will test your abilities It's a straightforward process though.

Thanks guys. I probably won't have an update for you until the summertime. Still looking for a new job. Took a risk by spending a little more on BFG's...then hours got cut back. Always happens like that.
