I mainly want the big V8 in a late model Tacoma for highway towing. Right now while going up hills I have to shift to 4th gear and really lay into the throttle with my 4Runner to maintain 65mph. I would prefer to be able to leave it in overdrive and not lose speed so badly due to the additional torque that the 5.7L engine could provide. I wouldn't want a 4WD to rock crawl or anything. I'd want to take a 2WD '05+ Tacoma and a 2WD 5.7L Tundra drive train and combine them. I might need to get ahold of my neighbor's 5.7L Tundra for an afternoon and take some exact measurements, then go over to my parent's place and take measurements of my dad's '06 Tacoma to see if this would work or not.
Thanks for the words of caution about the rear axle, but I don't plan to be rough with it. It'll be working hard, but at highway speeds -- it wouldn't be subjected to any rough or jarring traction/no-traction situations that tend to break things.

After the problems TRD had with Supercharging the 4.7, they put the 4.0 through thousands of hours of stress testing. That was a concern for me and when I contacted TRD, they assured me that the 4.0 is plenty strong to take the added stress of a Supercharger even while towing. Toyota is also very conservative and they are not going to put out a product or allow TRD to that they have had known problems with in the past with out a lot of testing.
What exactly do you tow? I probably push the Tacoma's towing limits just about as much as anyone (with out exceeding them) on a somewhat regular basis. The Tacoma pulls my FJ40 very stable, even at 75 MPH. It also has plenty of power to pull the 6,000 lb trailer up every pass I have towed over while still maintaing the speed limit. Don't get me wrong I'm not in 6th gear on moutain passes, some I am in 3rd, but the Tacoma has the power to pull and the engine is happy to work.
