sienna engine in place of the actual

Why toyota don't put the sienna engine on our tacoma in place of the 4.0 v6 236hp, we will had 3.5 v6 260hp so better gas mileage i think correct?

 

whats the torque on that motor, also the power range

 

x2? I think they probably looked into all options of the sort because it would have saved them money to use something they had, rather than develop and fund a whole new motor. It probably didn't produce the type of torque or was developed to operate at different injection rates for cruising. Cuz you know big companies like that wouldn't waste money when they could save it with some tuning. Example, i have an old ford truck in my driveway with a 460 in it, the motor puts out much less horsepower than the 360 or 390's of the time that came in their popular muscle cars, but throws down much better torque, for hauling.

 

3.5-liter DOHC 24-valve VVT-i V6
266 hp @ 6200 rpm
245 lb.-ft. @ 4700 rpm

4.0-liter DOHC EFI V6 with VVT-i
236 hp @ 5200 rpm
266 lb.-ft. @ 4000 rpm

 

Less torque at higher RPM's would be my guess, though not much

 

X2 and that it's probably more of a revver and isn't as nice for hauling...though that goes along with what you said.
