Luckily, we live in a free country and that's what spurs creativity. Some members on this board are modifying their engines by putting on superchargers for more power so what's wrong with putting in a diesel engine for better low rpm torque and fuel economy?
My diesel engine of choice for a Mark would be the 6.2/6.5L GM diesel. They are lightweight, relatively compact and very fuel efficient. They are also easily modifiable for more power. It doesn't take much to get 300 hp and 600 lbs torque out of this engine. The engine would be backed up with a built up 700R4 4 speed automatic transmission. A 6 speed manual would be ideal but I don't know where to find a 6 speed manual that would fit in a Mark and would also withstand the 600 lbs of torque from a diesel engine. Right now, I've got a clapped out diesel Suburban and I'm the process of putting this engine into a newer Tahoe. That combination would return 30 mpg but if it were in a Mark, I believe it would return 40 mpg with the excellent aerodynamics. For gearing, 2.73's would be ideal behind a 6.2L diesel
because the gawd dayum FRAME isnt designed for it you tard!
