They are different engines. The 04- Tacoma is the 3RZ-fe 2.7L and the 05+ is the 2TR-fe 2.7L. The 2TR has variable valve timing on the intake. I dont know what the difference in the bell housing bolt patterns are, or the transfer case. They are similarly configured in the engine bay but ??????
Yeah I knew they were different but I wonder if the difference is in the head only to arrange the VVT.
If the block is the same (I.E. the "fe" part of the engine names) maybe the bell housing is the same. If so then the earlier 04 trans and t-case could be installed giving the manual control. I already have the front ADD on a switch so my last step is to convert all the way to a manual t-case.
Right now I have the electronic control removed from my 06 t-case and I have added a lever to actuate the t-case manually. But the control requires getting out of the truck and cannot be done from inside currently.
Just trying to put the puzzle together. make this conversion happen. i really hate the switch t-case control.
