Is it possible? How hard would this be? I know the super duty's with 5.4L 3V's have the torque shift mated to them... I know the torque shift is an awesome tranny just wondering if it is possible to get them to talk to the 5.4L 3V in the F150 and work... I also was had another question? How hard is it to convert a 5.4L 3v to run off E85? I know it requires injectors and probably a tune and maybe new rails was wondering what else might be required.
The PCM in your truck will not work with the Torqueshift tranny. Mechanically things should bolt up, but wiring and electronics could be a problem. You could get schematics for the original truck and the SD 5.4L trucks and compare and trace wiring to see if it's fairly easy to do. I would probably be more interested in seeing if the 6 speed tranny would be possible myself.
My truck is a flex fuel and can run off of pure e85. The only differences I know of is that it has a larger fuel system including the lines and the filter. Engine and intake are the same as a normal truck. Maybe a different tune in the computer but as far as performance you won't see it. Not only are these motors peaked out for power but e85 isn't a high power fuel. You might even lose performance.
For the tranny the electronics won't play well together, like said above. My truck is flex fuel and I have ran two tanks of E85 and won't run it again. The truck had less power and got 11.5 MPG, it normally gets 17 MPG with mixed highway/city with regular unleaded. E85 just isn't worth it to me.
