Yep, it will fit, but it is tight. I have one half swapped in, but I'm abandoning the Idea for something lighter. The power is only fair, but tha t motor is heavy. If some one wants I'll make you a good deal on a 2.5 w/ a T-5 2wd transmission, stock harness and computer.
These motors are the tech4, also known as the Iron Duke. Decent motors, just I want to go a different direction.
