Re: Full power train swap question
I'm assuming the powertrain you want to use is an upgrade from your 3.7?
If so, I think would encourage you to really think twice about the idea. It would be a HUGE job to switch everything over, and no guarantee that things would work when all is said and done. These vehicles have so many electronic modules and components that are all integrated and programmed to work with one another, even after the physical change over of parts there is likely going to be a lot of switching over of modules, sensors, etc., for everything to work properly. Missing one will be a nightmare to trouble shoot, as the OBD protocols aren't going to be all that informative for such extensive work.
If you're doing it because it would be a fun/interesting project and you have all the time in the world, then maybe it would be worth it. If you are doing it to try and save some money, I think you would be better off putting aside the cost of the donor vehicle and use it as a down payment on the vehicle you actually want.
If you search the forum, there have been discussions in the past of similar things, most of which I believe end with the same conclusion...likely not worth it.
If you do decide to go this route though, I'm sure many members would love to hear about the swap and see pictures along the way!
