We have an 83 300TD and an 85 300TD. Due to transmission differences, the VACUUM systems are radically different, as displayed under the hood. The plastic lines are a veritable tangle of spaghetti in the 85 compared to the relatively simple 83 configuration. I don't know how this would affect engine swapping in the two model year 123 cars.

The 85 will work just fine, unless its a california version you wont have to change the manifold. Motor mount arms are the same. The IP is different although it should work fine. You will have to swap in the whole engine and trans together from the 85 though as I dont think the old style trans will work with the 85 engine. Only other real difference is the 85 doesnt have the vacuum switches on top of the valve cover, instead it has an electric switch to control EGR. Thats all easy to swap over. Just mount your vacuum switches to the 85 valve cover. Oh yea, the tach drive is different, the 85 gets its signal off the bell housing. The 82 off the crank. The 85 engine should still have the sensor there so that shouldnt be a problem.
