I have a 81 240D and I love this car, minus I do a long high speed drive on the freeway almost every weekend(well not right now I'm deployed) and the mileage isn't that great, but then again it has 210,000 miles, and I have no idea about the previous maintenance done prior to me buying it. Since I don't have a lot to do during my down time ive been searching the web and I know about the updated om616 in india, they don't make much more power even turboed but the torque has increased, has anybody thought, planned, or tried to swap one in along with the 5speed trans, looking at images and the factory engine parts manual they changed the intake manifold design quite a bit. I've already contacted a supplier in india, but I'm sure its not gonna be cheap but a newer om616 designed for a turbo, I'm sure that horsepower can be increased easier, so I'm stuck between just putting money in my original engine(needs injectors, and leaks a ton of oil and also smokes quite a bit after idling, thinking it might be the injectors) or attempt this swap that could be legendary
