it takes fab work on the frame to make it fit. i use sled clutches and have a piece made to bolt on the crank to accept the clutch and run a sled belt. i run a stand alone delphi electronics.  no more leg heat (ye ha) because the exhaust goes straight out the back. i relocat the fuel tank to the left side. replace the fuel pump with a high presure one but still in the tank. i have a way of making the 4x4 work but have not had anyone want me to do it. it does not use as much fuel as the 700 did under normal riding. because it does not work. it will ony do about 65mph but it gets there quick (wheelie quick).

putting an ecotec in a ranger can be done I have done 2 of them and have had good luck. and it all fits under the seat.
