300SD very sluggish at start? what adjustments?

I have recently installed a turbo motor and transmision from an older 300 into a 126 body. It has absolutly no pick up from the start. Especially on hills. Once the engine gets working though and the turbo begins to wind up it has plenty of charge and can easily move itself. What adjustments could be bad? I have replaced the timing chain, checked the start of injection timing, adjusted the valves, used lubra moley injection cleaner, and maxed out the linkage adjusments. What and i missing? Is their a vacume adjustment that could be missing that much? is there a linkage piece that often goes completely bad? could it be a fuel pump problem?

Bill is onto somthing, if this is from a motor swap did you get the overbost protection switch and plumbing from the donor car? Try temporarly running a preasure gauge T-ed into the boost sensing line that runs to the ALDA on the IP.
You should get From 10 to 14 psi at full throttle under load at 4000 rpm. You can adjust the wastegate and ALDA to max factory specs and really improve things. Also are you starting in first gear?

Fanatic,

Check out the thread started by Edge concerning this very same topic. I and others provided some checklists to follow as suggestions for improved acceleration. Rest assured, if your motor is generally healthy, there are things that can be done to tweak performance and make you happy you own a Benz diesel.
