anyone know if a yj 4.0 manifold will fit on my 90 mj 4.0? visually looks like it might. just wanna know if anyone has some solid info. or a manifold that will fit they wanna sell.

 

any help? man, no one's even looking.

 

Dont think so bud. 90 is still Renix, and the best of my recollection a Renix manifold wont swap with an HO manifold.

Wish it would have, i passed up a Renix Borla in a upull years ago.

 

ugh, i was afraid of that, thanks for replying. anyone else, i probably won't try unless someone has done it.

and of coarse i scrapped a renix manifold i had. when will i ever use this?

 

Plenty of threads at NAXJA mentioning the Renix to HO compatability.

Actually now that i think about it, if you can get the YJ head as well you can swap both to your MJ.

 

the head is going on my stroker. i had a renix head, supposedly rebuilt. i lapped the valves after porting and polishing, all to find out it was cracked. rednecks tried to weld it, i was the third buyer. that was what the manifold went to, and i chucked it.

oh well, anyone have a renix manfiold? is an xj manifold compatable?

 

Renix to Renix, HO to HO. Since all YJ's are HO's they will also bolt to any 91+ XJ.

 

thats what i figured. thanks.

 

your best bet is to replace it with an aftermarket one. i did on my xj and it add horsies and it wont crack. found mine on ebay for about 96 bucks shipped.

 

i've thought about it, i've heard of some cracking rather quickly. do they make a renix manifiold that has the flex pipes built in on the front and back to reduce cracking?
