The diesel Sentra was pretty rare! Great fuel mileage but slow as beans! The biggest problem with them was that when the injection pump failed, it usually cost more than what the car was worth!
I'm not knocking them; I was working as a Nissan tech in the 80s when they were sold brand new! The frequency of pump failures I cannot say; in 16 years as a Nissan Master tech and another 15 or so years as an auto technician in non-Nissan shops, I've only run across 4 diesel Sentras and 2 of them needed injection pumps, but that's a pretty small sample to make a judgement. I just remember that the pumps were ridiculously expensive back then....somewhere in the $2500-$3000 range from Nissan and that was back in the late 80s or early 90s? And I didn't say they were slow as s**t, I said they were slow as beans! Yeah, once they got going they were fine, it was the time it took them to get up to speed from a stop. But, with around 50-60 HP and 75 lb-ft of torque, +/-, it was what it was. It all paid off, however, with the 50+ MPG! Same with the diesel 720 trucks and diesel Maximas in the 80s, those engines were rock-solid when it came to durability! Other than the two pump failures, the only thing else I've even seen fail on any of the 80s Nissan diesels is a few glow plugs and an injection pump belt or two break due to lack of maintenance.Like I said... The car community doesn't"get" diesels. No, the diesel Sentra is NOT slow as s**t. Nowhere near as fast as your car, sure. Also , the pumps don't fail unless you don't change the fuel filter and it ruptures.. There's really nothing on the car to break unless you're a f.u.. This car goes 65mph in 4th gear and it is a five speed. I just want to get it into another collectors hands.
