Can you convert an e-torque engine to conventional?

    Is there anything special about them? I'm assuming just strip the e-torque motor off and that it's got a special front mount accessory drive that would need to be replaced with a conventional one?

    Anything else?

            I have a RAM with the e-torque. In addition to what you list, the special battery should also be removed (I think it might be behind the rear seat?). The e-torque also moves from 8 to 4 cylinder operation during low demand periods. I'm not sure if that is simply software controlled or if there in anything mechanical associated with it. The hardest part would probably be making the software changes so the computer does the right thing.

              Why do you want to remove it? They advertise them as the next best thing to sex

              I have an e-Torque in my RAM (not planning to remove it by the way).

              Some pros of the system are that the start stop system works well. I seriously HATE every start stop system I have ever driven; they suck. But this one doesn't, because it uses the "alternator" to start the truck back up. Since it is starting it via the crank and the truck is in gear, it moves the truck forward slightly as you are starting. There is essentially no difference than a regular automatic when driving it.

              It seems to me that mileage improvements of the system are minimal. Of course, I haven't tested any truck that is similarly equipped to mine without the e-Torque, so I have no comparison. But the mileage on my truck certainly isn't great, and I'm not sure I get a 1 MPG improvement that the e-Torque is supposed to provide. But maybe I do?

              I love my truck and I would probably equip it similarly if I bought it again, perhaps except for the e-Torque. The jury is out if it is worth it. If it truly gives me 1MPG better mileage then it is worth it. But if not, then it is expensive for very little added benefit.

                Well Hawk, for comparison, my regular olde 5.7 gets 14.6 mpg in shitty Chicago traffic. And 20+ on the highway.

                Sorry, was directing that question to the OP, he's asking about removing the e torque

                Me thinks he's in his lab cooking up some crazy combination. Or he just got a cheap 5.7 with e-torque and wants to stuff it into something. lol

                Yes, there's an affordable one I found to use as the 5.7 in my turbocharged 5.7/727 combo for my Coronet.
                But I don't want any of that e-torque stuff and I need a regular truck front for accessory placement.
                And will be running Holley terminator X most likely for control - no factory stuff

                  Mine's lucky to get 18 MPG highway running 75-77 MPH. But that is with "up to" 10% ethanol and my truck has the 3.92 (maybe 3.91 - don't remember exactly) optional rear and lots of other weight, so I'd assume it will suffer from those options.

                  Understood. I figured (and confirmed later by the OP) that he was transplanting an engine. But I figured I would provide my thoughts on the e-torque system in case there was any thought of preserving it. Might be easier to do than to remove it and reprogram?

                    Pretty sure it's 3.92. Mine iirc is 3.54. While I do have weight in the rear, oddly enough I think it actually helps with MPG. At least from what I have seen anecdotally.

                      But WHY would you want an e-torque power plant in lieu of the normal (read internal combustion engine) then ask the question about how to remove it? The attached article does not really explain the nuts and bolts of the e-torque set up and HOW it interfaces with the V6 engine and the rest of the power train. Is this an HYBRID design? The electric motor design and operation/conttol is not really explained in detail or what type of motor it is: conventional series wound (very high locked rotor or starting torque) or perhaps it one of the new "brushless" DC motor, aka electronic commutated motor, which can also function as a generator (i think) during deceleration (to help recharge the battery). But...maybe I'm missing the point all together......

                      Bob, it was a pretty good deal for a JY take out, that's why. Cheap enough to do some switcheroo.

                        BUT.....if its a JY take out, what about all the electronics involved....the wiring, the controller and accessories and of course the power supply, and all the adaptation required to successfully install it......and.....all the grief necessary to troubleshoot it when it doesn't work or perform to one's expectations.....including all the drawings and schematics of the origional system. First cost is not the underlying consideration (or maybe it is) and what about the ability to re-program the system, re-flash the memory mofule (with the origional programming software) should it be required (yes)...... its not as simple as the article portrays.... just my opinion of course.
