How do I know if I have a renix system.
New to the XJ world.... I have a '98 4.0L sport. I was reading Cruisers tips and from what I found searching, the easiest way to check if I have a renix system is to look for the check engine light. I will look to see if I have a wire bundle attached to my dip stick bracket?

Renix was an older set up, not sure of the years but I think it was in the 80s and early 90s model Cherokees, probably just the 80s. So u wouldn't have that set up

H.o has more horsepower and a closed cooling system. The cooling system was really the only thing I hated in my 88 was constantly overheating and such. Had I not sold the renix I would have eventually converted the cooling system. Renix is the era to avoid if you can however they're still damn good jeeps and I don't regret owning one. 1990 was the last year of the renix.

Renix in 90 made 182 HP. HO in 91 made 190 HP. That's 8 HP difference.
HO only made more HP than Renix at higher RPMs and not a bit more torque. HO had 58 mm throttle body versus a 52 mm throttle body on a Renix and also had a better design header. See where I'm going with this?
The whole 8HP was not mostly from the head, but from the bigger TB and better exhaust manifold.
Put a 60mm TB from www.strokedjeep.com on your present head, eliminate the "crush" in your headpipe with proper re-routing, and go for it.
HO stands for Highly Overrated.
