Jeep Driver Posted August 8, 2014 Share Posted August 8, 2014 Hesco sells the 2.5 RV cam for $289 and states that valves and retainers must be replaced. I'm looking at a master kit from Mabbco, they advertise custom cam grinds, RV cam is available for an additional $90. I called them this morning with a couple of questions and they tell me that If I go with the RV I will need to go carbed or change out to a 'learning' injection/ignition system, that Renix is not compatible with the cam. Have you guys installed a RV cam with Renix or early HO and not remapped? Link to comment Share on other sites More sharing options...
cruiser54 Posted August 8, 2014 Share Posted August 8, 2014 That's funny. Golen specifies a cam FOR a carbed 258 for their 4.0 stroker!! Link to comment Share on other sites More sharing options...
mnkyboy Posted August 8, 2014 Share Posted August 8, 2014 I haven't ran mine yet but from what ive read my MPI should be able to handle my Mopar performance cam. If not I will have to send out my ECU for flashing, I may end up having to go that route with all the combined mods to my engine. Not sure what you would need to do with the Renix setup.

Have you guys installed a RV cam with Renix or early HO and not remapped? I'm running a Hesco RVOB6 cam in the stroker, but I know that doesn't answer your 2.5 TBI question. The guy who will know is Benny Fulps at Hesco. Good go-to guy and knows about everything. I'd give him a call @ (205) 251-1472 and pick his brain.

Have you guys installed a RV cam with Renix or early HO and not remapped? The MAP that Renix uses is a simple Chevy style MAP. You can buy various MAPs by Accel like I did when I built my stroker. Look for 85-92 Camaro or 87-91 Chevy truck ones if you want a direct plugin. Link to comment Share on other sites More sharing options...
mnkyboy Posted August 8, 2014 Share Posted August 8, 2014 I got an adjustable MAP for mine, haven't played with it yet though. Link to comment Share on other sites More sharing options...

Benny's been around a long time and knows his stuff. They sell a lot of RV cams for the Renix 2.5's and 4.0's. Mine at first was in an OBD1 system and no remapping was required.

Eagle Posted August 9, 2014 Share Posted August 9, 2014 Hesco sells the 2.5 RV cam for $289 and states that valves and retainers must be replaced. Valves, or valve springs? I can't imagine any reason to replace the valves, but most cam kits either call for or require new springs, new keepers (retainers), and new seals.

I can't imagine any reason to replace the valves, but most cam kits either call for or require new springs, new keepers (retainers), and new seals. 2.5L performance four cylinder camshaft. Enhances torque through out the RPM range. Smooth idle, not choppy. Once these camshafts are gone there will not be any more produced. Lifters not included. Advertised duration: 264 214@ .050 Lobe centers: 110 degrees Lift: 470 This camshaft will require a spring and retainer change because of the increased lift. Failing to do so will cause severe damage to the camshaft and related components. If the valve stems of your valves have triple grooves for the keepers they will need to be changed to the early single groove valves. Valve spring, retainer and keeper kit: HESSPRSS4 Valve spring, retainer, keeper, and valves: HES25VSRK Link to comment Share on other sites More sharing options...
Jeep Driver Posted August 9, 2014 Author Share Posted August 9, 2014 Yeah, I could end up with $500 in a head, $300 in the cam, rods and lifters..........and I really want the double roller timing set too........another $200. You know the story......wheels or tits.......... Link to comment Share on other sites More sharing options...

And you know that your valves have the triple grooves? If not, you should be good to go. Link to comment Share on other sites More sharing options...

They say they cannot flash my MPI ECM or any other Jeep ECM. Link to comment Share on other sites More sharing options...
