Audi 90 quattro TDI: should I tear down the WVO TDI?
Hi All,
I am about to begin putting an AHU tdi into a 1990 audi 90 quattro. I have the physical logistics of the swap pretty well worked out, but my only real question is gearing. There isnt great options for quattro diesel transmission in the US, and I really want to use the stock trans for cost reasons. I live in the mountains and the vast majority of the driving is about 60 miles of backroads a day with 20 miles on the interstate where most people drive 65. So this car would be going 50mph most of the time, sometimes 65. I am one of those guys that drives 65 on the highway on long trips too. That being said, I calculated that the engine would turn about 2800-2900 rpm at 65. I have a 1.6 ecodiesel jetta and it screams on the highway and gets great mpg, have never really driven a tdi. Is this rpm too high? The doner car has a blown clutch, so i cannot experiment with it to see what 2900 rpm crusiing feel/sounds like. Would I expect running at that rpm to negatively effect rpm?
Here is the pretty old girl in question.
