Cat free exhaust parts???
davidlandy:
I have took the CAT from my 90 300tdi and replaced it with a straight thru pipe - it made a very noticable difference to low end pullaway throught to mid range. You can now hear the turbo singing more happily. I would recommend it. Took it for MOT passed ok.
blanked off the EGR last weekend after I finally got those fiddly allen bolts out of the manifold. Was gonna let Mr. Angle Grinder in on the action to speed up the job, but perserved and got there in the end with my allen keys and a ring spanner for a bit of leverage. :D
Havent driven it yet to see if there any difference.
only thing left to do now is cure the black smoke I get when before the turbo spools up.

use 2 'ickle screw drivers to remove the 1" plug on top of the diaphram on the pump, turn it in 1/4 turn at a time, lock nut is 110 Flb tight 8)
Cal:
I need to adjust my smoke screw as well - just to make sure I'm reading it right - do you mean do 1/4 turns clockwise, or anti-clockwise? :?
Cheers :D

Probably best to post the links so you can read for yourselves. The best improvment was to turn the fuel supply screw in on the back of the pump, much better (ask Jake :wink: )

What a difference this made to mine!
Smokes like the red arrows on hard acceleration but beats boy racers off the lights!!
If i drive it sensibly it smokes no more than usual.
