Diesel CJ5 Project, need Trans and Transfer case advice
DieselJeep
Jeeper
Hi everyone!
My project is a first for me, as It's my first 4x4, and first diesel(even though I tried[and was horrible at it] to sell Jeeps in late 90's, and service/repair semi's at work)!
So, I need some sage Jeep advice on a good choice for a 5 spd and transfer case for my Mid-70's CJ5 project with a 1.8L 4FB1 Isuzu diesel.
Goals of the project are:
1) Mechanical injection exclusively
2) Cheap Fuel
3) Improved Power
4) Reliability
5) Simplicity
6) Cost
7) Fuel economy
All of these are a balance, and variable to a point.
Forced induction is in the works, goal is @ 150-200 Foot lbs. torque.
No, I am not trying to build a voraciously thirsty monster motor. I'm done with that stuff. This will be a daily driver, that is fairly capable off road. Suspension and axles will be stock. I'd like @ 25 MPG+ on highway, but don't want a slug that Grandma gets mad at on the street.
PO says the factory stock axles are @ 3.78(or 3.86) I believe. Somewhere @ that.
It came factory with an I6, and 3 spd., but those were left behind.
With so many parts choices, I'm having a hard time sorting what would be best. Some say T5 is weak, AX15 is good, transfer case output wrong side, Ect...
Thanks in advance for sharing the love and wisdom!!
