I have jumped into a couple other threads that were related to what I was doing, but I guess its time to start a new thread for my project. I called it 4bt Durango #2 because of the other Durango project. For those who haven't seen my other posts, here are the details:
4bt from a Chevy bread truck, which I haven't seen (should be coming home Friday)
Dodge gas version NV4500 (so it will bolt up to my Durango t-case), and a Cummins input shaft.
Clutch is Napa Dodge Cummins, new replacement, including flywheel and all bolts
Hydraulic system will be Dakota pedal assembly, Dakota master cylinder, going to Ram slave cylinder.
Durango NP231HD t-case, which was behind the 5.9 motor.
Front suspension will be stock, so the oil pan will be heavily modified.
This will be my wife's daily driver, and our lighter duty tow rig (I have a '96 Ram Cummins for heavier loads) so it will be a study of economy and comfort,. meaning it must be as smooth and quiet as possible. She has driven my Ram enough to know what a diesel is like, but I'll do my best to make this a nice vehicle for her.
Now for my newest questions. For those who have installed the 4bt into later vehicles (such as the Grand Cherokee, Durango, and other late model vehicles), what is the best way to keep my gauges working properly? I'm assuming I'll have to keep the PCM to read the speed and transfer the signal to the gauge cluster, and the same goes for oil pressure, temp., etc., since the gauge cluster only receives a computer signal from the PCM, not individual signals from the sensors like older vehicles.
For the tach, I think one of the tach adapters from Dakota Digital might work. They are made for diesels, and I should be able to adapt the signal from their sensor to the Durango's tach somehow. If not, I could eliminate the Durango tach and install an aftermarket tach. Any thoughts?
I already have EGT and boost gauges, and will be getting a fuel pressure gauge before the project is finished.
I'll have more questions as the project begins this weekend, when I pull the motor from the van.
