80 300td vs 83 300d(turbo)

Hello , I am writing to find out how much difference there is between a 1980 300td wagon vs a 1983 300d sedan when it comes to pick up. I intend to use traditional diesel and am looking for a daily driver in the ny 5 boro area much of which will be highway driving with short on ramps. I have leads on a beautiful 80 wagon but am concerned that its not a turbo and have heard they are sluggish, i guess i am looking for a definition of sluggish.Thanks in advance from a relative newbie-T

81 300d Cold Air on Highway

Interesting problem. I have a 81 300 d non turbo. Heat works fine when driving around town in a city type speeds. Temp stays right around 80 degrees Celsius. When I get on the expressway, at roughly 55 mph it cools off after about a minute. Temp gauge still reads 80ish. I added some cardboard behind the grill still with no improvement. I'm currently running diesel in it even though I have a Lovecraft waste oil kit. Any help would be great. It's going down to negative numbers tonight here in MI so it should be a cold ride to work in the morning. Thanks in advance.

81 300d Brake Pedal Soft

I'm at a loss with a brake problem on my 300d. I lost brakes a couple months ago and since there were no signs of broken lines or anything like that I assumed that it was the master cylinder. I replaced it without bleeding the brakes. The brakes were better still with quite a low pedal but the vehicle was stopworthy. So I finally got around to bleeding the brakes to no avail. Still a low pedal. Also, when you pump the brakes to get a hard pedal, it's almost like the braking force is exponentially decreased.

82 300TD Semi Functioning Driver Window

I am about to take my front driver side door apart to repair my window,
according to Kent's manual on 123 door repair...
The window motor works fine, the mechanism is just not pulling the window
down. the regulator comes down, because I can then open the window by
pushing it down, and then when I push the button to close the window, the
regulator pushes the window up fine. Do you have any pro tips for what part
I might need to remedy this situation. I have already purchased a regulator

83 300D turbo ATF fluid in vacuum lines

My 83 300D Turbo recently developed some quirks such as: surging/lurching while driving, not shifting properly(rpms getting way too high), and not engaging when put in gear. When looking under the hood, I happened to notice pink fluid flowing through a couple of the clear vacuum lines. I assume this to be ATF fluid. I began testing vacuum at various points, and found that the vacuum device on the drivers side of the transmission didn't hold vacuum, there were a couple of other connections not holding vacuum as well including one on the vacuum device mounted near the IP.
