I own a 02' tacoma access cab 4x4 automatic with the 2.7L 4 cyl motor (78k miles). My question is in regards to the motor itself. If i undertsand correctly this motor is still available in the newer 2nd gen trucks also. What are the major differences between the 2.7 in my 02' tacoma and that of the newer trucks? Is there a difference in HP and Torque? if so how much? are the newer 2.7 motors more fuel effecient? does my 2.7 need to be maintained any differently than the newer 2.7 motors? any info would be greatly appreciated. I am new to the tacomas and would love to learn more about them.
