Not sure where you thought I was being rude. If anything I am trying to save you from the same mistakes I made.

I was given 300sd, I doubt that intercoolers are a waste of time seeing that almost all new diesels have them even if I get 2 mpg I'll be happy. Stigan Is an American company, not Chinese btw.

American company, chinese turbos almost certainly. They would list made in America all over the place otherwise.

If you really want to go for an improvement without increasing fuel get a gt22xxv.

It's going to be awhile before I have the money to sink into this project. When I do the improvements I'll post results to help people in the future

good luck!

the 2.47 diff will make a difference in economy, you might want to get a Torque converter from an 85, it has a lower stall speed, for better acceleration with the tall diff...

the 85SD can get 30mpg with average driving, with the 2.88 diff. (I did it regularly in my SD) if you feel an IC is worth it, let us know the results, but I recommend getting the car solid before adding the IC, so you know what made the improvements.
get the diff, in and record the results of that, log miles, mpg, and times to 60/30/45, etc... then add the IC, and record the changes.
OR ad the IC first, and record the changes from stock, then make further changes.

If you do decide on an IC, I have a use bmw one that is probably a perfect fit. I got it for the W124, it is a good fit under the bumper with 3" in/out. This one on top:



Will let for cheap, the plastic end tank was broken in shipping (idiot didnt put ?ANY? packing around it). Could probably fix with some good glue or plastic weld.
