The kubota Diesel engine swap by overland diesel has me intrigued for my jeep. You get great fuel mileage, lots of torque, same hp and it is very simple and reliable. Only question I have, and maybe you guys can shed some light on it is, the kubota only revs up to 2800 rpm. The L head will go up to 4000 rpm or so. I was curious how the lack of rpms would effect my jeeps wheeling ability. Would the added torque make it so I would be able to use a higher gear? My jeep has a T18 and overdrive, so I have 8 gear choices. Lots of times in say mud, 2nd is too low and 3rd doesn't give me enough wheel speed but 2nd od is perfect.
