benjy_26 Posted January 11, 2015 Share Posted January 11, 2015 Is the Renix 4.0 a good engine? Undoubtedly. Maybe in stock form the 4.0HO didn't blow the Renix version out of the water, BUT the power potential of the HO engines, from what I've seen, outclasses the old Renix mills.

Comanche County Posted January 11, 2015 Share Posted January 11, 2015 There's a reason why there are more HOs in the bone yard than renix models. Its because HO owners aren't as intelligent as as Renix owners. They simply don't know how to change the oil or check the coolant. Link to comment Share on other sites More sharing options...

FrankTheDog Posted January 11, 2015 Share Posted January 11, 2015 Almost alll the renix MJ's and XJ's I've had we're rotted out and on their last legs. Bought them for the Dana 44's that were in them. Link to comment Share on other sites More sharing options...

shelbyluvv Posted January 11, 2015 Share Posted January 11, 2015 I own two Renix MJs. Now they are OBD-I and OBD-II. They Renix system is garbage. If you like it more power to you (well less actually). I will convert every Renix Jeep I own to OBD-I or II first chance I get. Link to comment Share on other sites More sharing options...

Incommando Posted January 11, 2015 Author Share Posted January 11, 2015 Agreed on the HO. Never had a problem with my Renix era Jeeps. 88 is the perfect year to me. Highly disagree on the VM engines. You couldn't pay me enough to put one in something. Not getting the new Cummins (the sole thing Ram has had going for it for 20 years) to use a VM diesel was the stupidest thing Fiat could have possibly done with the brand. Even if the new VM diesel is a good motor it's sure as $#!& not a Cummins and the name doesn't carry the weight or selling power that Cummins does. Who said Cummins was being discontinued in the bigger trucks? The vM is going into 1/2 ton trucks and Grand Cherokees. See what Gale Banks thinks of them. I didn't say it was being discontinued. I said they're not getting the NEW Cummins and they're losing exclusive use of it since Nissan is getting the new one in the Titans. I can slap a nice header on a piece of $#!&, it's still going to be a piece of $#!&. You shoulda heard all the negativism about the XJ from the Jeep purists when it came out..... Amen. Those old enough to remember that time know that Jeep people considered the XJ as the end of Jeep. Heck jeep had print ads comparing it to a Volvo 240 station wagon!

Comanche County Posted January 12, 2015 Share Posted January 12, 2015 Funny you mention a 240. Lately I've been looking for 240s to pull Dana 30 LSDs. Link to comment Share on other sites More sharing options...

FrankTheDog Posted January 12, 2015 Share Posted January 12, 2015 Almost alll the renix MJ's and XJ's I've had we're rotted out and on their last legs. Bought them for the Dana 44's that were in them. What are you saying? I'm saying they weren't worth doing all your tips on to make them run better and nearly all of my parts for XJ and MJ's are for HO's. So all the renix jeeps I get end up as donors. They're usually in rough shape requiring to much work. I'm usually the end user of all the vehicles I buy. I've chosen 92-99 HO's to drive about 10 years ago. I've learned how to fix and repair them and I don't need to hire a mechanic 99% of the time. Link to comment Share on other sites More sharing options...

If you like your Renix, that's awesome, but saying that airflow has nothing to do with power is ,at best, mistaken. I never said flow doesn't make power, it just doesn't have much of an affect on low end power. A stoker is an undersquare engine so by design it is more suited for making low end torque rather then top end horsepower. And actually I like all the 4.0 sixes I just don't see the updated versions as being much better than the originals. (Then again I still like the old 4.2s) Link to comment Share on other sites More sharing options...

(Then again I still like the old 4.2s) Again, not everyone wants or needs to enhance power down low on a L6. Different strokes, I guess. I will maintain that the AMC designed L6's that I've seen putting down big power all have been running the HO management system. Whenever I see a Renix putting out close to 300hp without forced induction, I'll change my tune. Link to comment Share on other sites More sharing options...
