I just swapped a 2000 4.0 into a 1997 .problem is I cut the headers on the 2000 motor when taking it out. Can I use the 1997 ones? I know the exhaust ports are smaller but will it still work?

 

Ouch.

I think you can, do the holes line up?

 

NO IT WILL LEAK I JUST DID THE OPPOSITE PUT 96 HEAD ON AN 01 GONNA HAVE TO CHANGE THE WHOLE EXHAUST IT SUCKS IF YOU NEED THOUGH I GOT THE MANIFOLDS YOU NEED PM ME IF YOU WANT TO MAKE A DEAL

 

Thanks for the info!

 

I know the 2000 and 2001 have the cast intake manifold, 4 o2 sensors and 2 cats IIRC. I have a 99 xj which has the 00-01 intake manifold but older style header.

Anyway if the 99,00,01 have the same head, then couldnt you use a header that fits a 99. Unless, are the heads completely different from 99 and older to 00-01?

 

Just go with a Banks..........

 

Yeah. For something like $500.

 

Hey, I never said it was cheap. I did with my old TJ and was happy. I guess I go by the philosophy of "If your gonna do it right, do it right the first time." That thing is a PITA to replace. I'd rather only do it once........

 

What's the best way to get the bolts out? I heard that if you just cut all the heads out you can then get vice grips on them and get them out?

 

I have a Borla header for my wifes TJ. But I only paid $100 for it slightly used.

Have you tried to get them off yet?

 

Ive pulled the manifolds a few times no problem its the flange at the bottom that breaks studs heat soak in pb blaster impact on low speed go to go

 

Im sending the head from the 97 out to get checked for cracks. Just going to use that one. It's the better head anyway
