Definition of "older engine"? :shrug:
I installed a turbo kit on my F-250 at approximately 158,000 miles; 9.5 years old. At 295,000 miles and 26 years old, it's running as strong as ever and getting the best fuel economy ever. Original engine and clutch. Had to replace release bearing at around 240K miles. Five sets of tires since I bought it.
