Hello all, I'm new to the forum so I apologize if this is in the wrong section but it seemed the right place to start. A couple months ago the girlfriend and I purchased a 2000 durango with 5.9 magnum and 46re in it for 450 dollars. Had 200k miles ran well but trans supposedly slipped which was fine as she wanted the brand new bf Goodrich tires from it plus any little parts we could swap into her 02 durango which has 4.7/545rfe( I believe) and was poorly maintained by PO but only has 90K miles. So I took off everything she wanted and set my sights on pulling the motor,trans and everything connected to the wire harness aside from door and seat wiring. Got everything out suprisingly easy(note: I scanned for codes before pulling and none were there although probably due to the dead battery). Anyway plan is in the works to update/rebuild everything alittle more robust and custom install into my old 93 g2500 Imperial conversion top van (sick of dealing with the 4l60e trans after going through 3 in a year and a half, plus I've wanted to update to obd2 for awhile). I'm already aware I'll likely need to make custom motor mounts and get a driveshaft made but I wanted opinions on what stall torque converter would be appropriate since I don't trust the stock one that came with it. I believe the rear in the van is a 3.9x ratio and I'm running 235/75 R15 tires. She's definitely gonna be hauling a bit extra weight with a second fuel tank, on board compressor/tank setup, hd front winch and possibly propane setup for either dual fuel or just propane injection to boost octane. Plus I tend to haul a lot of junk to the dump or to my fathers barn to be harvested for parts. I'm also considering a turbo setup but using those ebay exhaust valves on exhaust and intake so I can turn it on or off. I would probably only set to 10 psi if I do this and I'm aware it will take up ALOT of space and take a fair bit of welding but I like to experiment. Curious whether 2 small turbos or one bigger turbo would be better for this and if single setup is it better to feed from both manifolds or just one? Anyway here's a list of things I plan to upgrade or already have purchased. Purchased items will have a * before them.
*double thick alum. Plenum plate + kegger/tb mod
*double roller timing set and tensioner
aftermarket sparkplug wires
* shorty block hugger headers ( may have to modify as the look like they will dump right at motor mounts)
new plugs/dist. cap/rotor/belt/pulleys/waterpump/gaskets
reman heads (if I can't salvage current ones after removing exhaust manifolds)
hyperuetic pistons/ moly rings ( if I do turbos. Anyone used these? Seems to be only reasonably priced upgrade pistons for these motors)
*02 dummy signal kit (since it's historic, no need for a cat)
* master rebuild kit from Transworld or transmission world
*hd front and rear band
*junior shift kit ( of course when I went to install i found it was already upgraded)
updated alum. Servos and accumulator
hd wedge and strut
*aux parallel trans cooler and lines(deleting inline drainback valve)


well that's currently all I can think of from my list at the moment. I will edit later if I think of other things. Thanks for reading and let me know if you have any input or helpful suggestions. I look forward to being a part of the community while learning and helping others as best I can.
