Okay, so I have a kind of strange question. I've always been fond of the idea of performance diesel engines and biodiesel (made from either waste veggy oil or hemp), but trucks are too large, and most diesel car engines are small. It is a fairly common practice to leave a V8 engine into a 350 SBC 240/260/280Z datsun, but I'd be more interested in a V6/V8 diesel car a Z. Are there manufacturers that offer diesel box that could fit under the hood of a car Z? What about transmissions (6-speed manual preferred)? Like I said, weird question. And so today I learned that … I would have to say no. First, a GM. 5 7 diesel DO NOT turn a Corvette transmission. The. 5 7 (a. KA 350) is a gas block Oldsmobile they tried to do on a diesel. A Chevy transmission will bolt to not block Olds. The 350 diesel engines were rubbish anyway because the bottom was not strong enough to handle the increased compression resulting in cracks in the main webs and broken crankshafts. Second, while I agree that diesels are heavier, is not due to greater compression. They are heavier because of the extra material in the casting required to allow the block to handle the increased compression. If I remember correctly, many of these old cars Z comes with 6-cylinder engines online. Although I have no idea what the dimensions of these engines are, it seems possible that a Cummins engine in a Dodge truck might work, since it is also an in-line 6. With the torque produced by a diesel engine, the changes Car of the uni body structure and suspension and transmission that would simply be too probably need to be a realistic exchange. It would be one of a certain class, however.
