I came across a brand-spanking-new 2KD-FTV and I would like to put it into a 4Runner. This is my first swap! I just have tons of noob questions and I hate to be a bother but you all seem like the friendly and helpful types who know their stuff. I am looking at an early 2000's 4Runner (4th Generation) to slap this baby in based on the type of engine and the rudimentary research I am capable of. I know I need a new wiring harness and ECU.
Basically, here is the list of questions:
1) Do I need to replace the Transmission? If so, which ones would be best (A340F, A343F, A750F, etc)? To keep my better half happy, I need to keep it Automatic.
2) Do I need to replace the Transfer Case? Right side versus lift side transfer....
3) Do I need to replace the differentials?
4) Does the engine wiring harness attach to the rest of the electronics in the vehicle (i.e lights, stereo, power windows, etc.)? If so, would I need to splice different wiring harnesses together to route power? (This is the part I am most foggy on.)
I think that's enough for now, I of course have a billion more questions. But I think those are the biggest cliff hangers I have before I buy the vehicle. And thanks for the help in advance!
