Far better to have both suck out the heat with a passive intake vent
Pressurizing the engine space could cause exhaust fumes , and the general hot stink of an operating engine enter the passenger spaces.

I agree with FF above: your diesel engine(s) is a great air intake fan already...you just need to ensure the intake vent area matches the requirements of your total HP. Engine room fans should be dedicated to exhausting hot air (which will in itself help draw fresh air in). (Again, unless you have chosen to go down the Delta-T slightly pressurized pathway.)
