i have a 83 300d turbo diesel, original owner since 1983 and this thing has nearly no torque at all when i punch it, i had a 85 300d with amazing torque and it would attack almost 90 degree hills. it had 165,000 miles.

to make things short i want my 83 to have that torque. the motor and tranny has 138,000 miles still on the original injectors. it has 10 pounds of boost but i hardly feel it or hear the turbo, it has no turbine play or anything, i did clean the banjo bolt, fuel filters replaced, the alda is still a virgin and has never been touched either haha.

Could my transmission have a role in this problem? my 85 produced enough torque it did burnouts. my 83 wont get the tires to spin in the snow.... right now the 83 shoots a light coating black smoke when pushed hard driving on the road. could my exhaust be clogged since its still original too?

Thanks alot i would really like to get my car fast as it use to be.
