Posting a question to the ether:
What kind of fuel mileage should I expect from a 240d 4spd with a OM617.95x swapped in? I could also swap the rear axle from a 1985 300d.
My current car is said 1985 300d with 192k, vacuum leaks have been fixed, new injectors a year ago, not yet done valve adjust. Everything else stock.
My car has body damage and a salvage title, plus bad HVAC system.
I have a line on a mint 240d in perfect condition but for a bad top end on the engine. I can get the car for cheap, and figured I could sell off the parts I didn't need after the swap to recoup my investment.
I get 25mpg pretty reliably right now, so for it to be worth the time and effort, I'd want to get 35+ after the swap, keeping the a/c system.
I've read lots of posts about swaps, but no mpg numbers for this specific setup.
Thoughts?
Thanks!
