I have the VW 1.9TD-M in my 4 door suzuki sidekick .. It's been converted for 4 yrs now .. I have to tell you I use the ACME install kit , and there is no such vibrations your talking of ... I have the original harmonic balancer removed too , running the V-belt set up from the older VW 1.6 , so I feel that is not your trouble .... 
I too am using the suzuki sidekick engine mounts with the diesel , and many have with out the issue of vibration .. That being said , I think they could still cause your trouble !! Here is why :
The suzuki mounts as you are aware are made in such a manner that the outer metal housing will go down and bottom out against itself if the mount is worn or soft from extended use .. You must also remember the diesel engine as much more torque than the gas , so if the mounts are worn or soft this problem would not of shown itself until the diesel was installed , and the torgue was applied to them .. In other words , the diesel engine could be causing the worn mounts to bottom out .. 
.
I would try a NEW set of suzuki engine mounts , to at least rule out this problem .. Also the mounts from the later suzuki sidekicks are about 1/2" higher , due to the fact they have more rubber in them . These would be the best to try ............
Just my two sense worth ....................... N-Z 
hello thanks for your attention. first of all the info about using the engine without harmonic balancer was very usefull mfor me. i wi9ll ot have to buy one to test it
now about the mount. i have 1 mount from late vitara (big one) and the other from my vitara (smaller one) both are in very good condition and work perfectly, no vibration is felt on the body. i am familliar with engine mount vibration and i can say that it is a different beast
in my case it vibrates like mobile phone vibration alert , but it has higher frequency
. i dont even feel it on the body, it is most of all felt on accelerator pedal and gear lever (when accelerating in gear)
also, if your idle speed is too low, the engine will shake like theres no tomorrow, even a good running engine..
no, on idle it is quite smooth and revs are somewhere between 700-900.
last two days i have noticed that accelerator pedal starts to also starts vibrate lightly at about 2000, then it goes away. and when i reach 3500 it starts again but now vibration is way much stronger and it continues until about 4000rpm. the vibration is accompanied with strange vibration sound coming from an engine. and foam appiers in return line
it is impossible to hold revs in that range. it feels that something is gonna fall off if you don't take the foot of the accelerator.
it happens when it is in gear or in neutral. as as i remember it also vibrates off the throttle. doesn't matter if the clutch is depressed or not.
can faulty and worn out injectors or injectionpump cause that problem?
i have balanced the flywheel so imbalance is excluded.
i'm afraid not to damage something...
