Kills *all* of the vortec engine's also. Especially the new ones with the BS 4 second closed-loop at WOT. wow... Horrible!
The Nissan engine is great also.
Sorta hard to compair against the LS's. I would imagine you could get alittle more power with a bigger powerband unmodified FI on the 3ur-fse. It's definately better economy & far higher technology, but if you were buying & rebuilding the LS would be sooo much cheaper.
The good newst, IMHO is that in 5 years they'll be real cheap to buy & play with. Toyota engines used are abit pricy, but not too bad once thre is a big supply. Plus, so high a percentage of Tundra's are being sold with them now. It'll take awhile but they'll wreck some of them!
