For the 03/04 its pretty much a bolt on, you have to flip the throttle body over but that's about it. The 00-02 (like mine) requires an adapter or redrilling the bolt holes on the TB. The adapter I made causes the bottom of the throttle body to pinch the upper radiator hose. I am still trying to figure out what to do about that.The manifold is a direct swap I assume? I’ve been in the tundra game for 7 years now and have never heard of anyone swapping to the 05/06 intake manifolds. What is the difference and advantage?
I swapped a J shift when I did this the first time, so no electronics. When I installed the first J shift, I also swapped to a cable operated twin stick. After driving it for a few months, the case started acting up and it ate up the 2/4wd syncro. I don't know exactly what caused it, but something caused it to try and shift into 4wd on the highway. It probably wouldn't have been an issue if the hubs were locked but since I have manual hubs, the front driveshaft was spinning at 0 rpm and the rear was at highway speed.How do you shift the stock tcase? Did you also swap in the 4x4 electronics?
