Okay am am running out the door to wash and wax the 85 300SD and take my folks ( 85 + 86 years old ) to a USMC reunion and then Tuesday to a Memorial Dedication at the USMC National Museum. Please excuse my rush. I have not done a search yet but does anyone have a link for some of the basic performance mods on this engine/car. And good details as to what each mod does and effects. I have always liked to do one mod at a time to see and evaluate the change both positive and negative. Also the rear end gear ratio on this car. Can I get the ration from the Stealership ? ( this car is original except for the IP which was replaced under warranty early in it's life)
I am looking at 3 things in particular:
1. Alda adjust / remove and the 2 lines going into it.
2. EGR remove and block off plu the vac line
3. Delete center resonator ?
4. I have seen a few people change the filter out to a remote location as in the 300D.
5. Check the boost pressure, where to connect gauge to check.
I have read many of the threads but I am certain not all. If there is not a single video/ photo step by step instruction link maybe I can make one with some detailed help from some of the gurus here.
My son ( Boy Scout ) and Daughter ( Girl Scout) want to do the video portion and learn about the car in the process ( as does my older daughter who wants the 85 as soon as she gets her license----- FAT Chance !)
Thanks I will search through the threads again and see what I find but was curious as to if a great one already existed. Anyway here I go Wash, Buff, Wax, Clean the interior, reinstall some interior pieces. Install new headlight
and change the oil. Oh also rehang exhaust so it stops rattling. Have to be done in 3 hours so I can pick up the folks ( 30 min drive) and drive them to
USMC base ( Quantico )
Later.
