W126, BENZ AID - COMMON QUESTIONS AND ANSWERS

Quick Question - Can I remove the engine(dead motor) from a '75 W115 300D and replace with a long block turbo OM617 (will not be using turbo set up-just long block minus turbo) and then swap over all the W115 specifics, oil filter housing, IP,manifolds etc,motor mount arms, etc. Easy or is there something I am forgetting? Thanks!

After approximately 2 weeks of sitting, I started my 75 300D for a few minutes to move another out of the garage. Then about 1/2 hour later I started again to move back in the garage (ran engine for no more than 2 minutes). Next morning she wouldn't start. Would crank and blow black smoke (more than normal) but wouldn't start. Pushed out and let sit in the sun for an hour. Restarted, runs fine.

Any ideas would be appreciated, thanks.

I bought this car for my daughter with only 83K miles. Compression is good at 165- 170 PSI on all four cylinders (cold). I have tuned it up with new Bosch plugs (non platinum), cap, wires and new injectors. I also replaced the fuel pump, filter and reserve chamber for hot starts (the name escapes me right now). The car runs great but the fuel injection system doesn't kick up the RPM's when cold. I'm assuming its something in the Bosch CIS system, but parts are very dear and I don't want to throw money at a guess. Any suggestions would be appreciated.
