I changed my 85 cali over to like a 83 is set up.

Changed the down pipe,intake/exhaust manifold, turbo to pre avr. (84 - 85 have it).
get the manifolds off a 78, 79, early 80 w116 300SD, this is pre EGR, think the EGR was installed in late 80. then nothing to block off.

use a air filter like the federal one, or modify the cali filter. the turbo will sit a little lower, so the turbo inlet and the outlet pipe on the filter housing are at the same level. might have to cut the pipe and fab up a hose for the inlet.

the 85 doesn`t have oil drain from the air filter to the pan like the Fed set up. the 85 cali is A GOOFY set up the way the oil vapors connect to the housing. It "T`s" off to the filter and straight to the inlet just before the turbo. Just run it into the turbo inlet.

when we changed it over it was a different car. especially at higher altitudes like 9000ft - 10,000ft elevation. before the change, it was a dog, after, ran like a raped ape.
as far as milage, I don`t remember.

the cali starter is about twice what a Fed starter is. and also the cali turbo costs more, as well as the down pipe.

the best improvement, is when we pulled the automatic, and swapped in the 4-spd. incrase of 2 - 3+ mpg. 29 to 31.94mpg on the last tank.

check with the dealer, they should have a record when the trap was changed the last time.
