I have a 89 wrangler I am replacing my engine with a new 2.5 and I also need to do headers cuz I have a crack in my intake and exhaust manifold. Does anybody know of headers that will fit my jeep I'm having a hard time finding any

Ok so just a question why are you replacing with a 2.5l

It is not a bad engine per se bit certainly not the most powerful?

Is this a daily driver mall cruiser look purty up in your 4wd?

Sorry the last sentence was third beer talk

No offense taken haha and no I am a broke college kid and my engine completely crapped out on me so I need to get it up and running again I mean I'd love to put a bigger engine in so I can have more power especially since i have a 4" lift and 33s but my financial situation right now won't allow me to do it

I'm not sure what else is involved with an upgrade/swap, but the 4.0 block can't be that much more than a 2.5.

Again tho... I don't know what else you'd have to upgrade.

You might want to post on here your vehicle info there is a lot of knowledge on this forum and people can steer you in the right and most economical direction if you have already spent the money it is a mute point.

But if you have not give us details as much as you know and we can ask questions for the rest!

Yeah, your right... Trans. You prolly have the AX5 and you'd have to go to the AX15.

Your right... The costs start to add up.

I have Borla on my 4.0, it did make a differance but they are not cheap and I'm not sure how much you'll feel with the 2.5.
Borla Performance Industries High-Quality Austenitic Stainless Steel Exhaust Header (87-91 Wrangler YJ w/2.5L) 17061 - Free Shipping over $75!
Ya I saw those on another website and that's why I wanted to see if anyone knew of any others because they are so expensive...also when I talked to the guy on the phone from the company he wasn't sure if I was aloud to use the borla in California because it might not pass emissions does any one know anything about this

I know they are legal on the 4.0 because I'm in Cali and just passed mine. Did you talk to Borla or a reseller? Borla can tell you if it's CARB approved, it will have a metal tab on the header for the inspector to see.

What about the fuel injection 2.5 because that's what I have and I wasn't able to talk to borla they had closed before I got a chance to call them

I have the pacesetter header and love it. Just passed SMOG in SoCal just this April. Also my Jeep sat for 9 yrs before it went through SMOG.
