Some of the later starter motors were increased in power to turn the engine more quickly improving starting. I have just fitted a new one to my C5 hdi and that was rated at 2.2kw which equates to about 2 bhp, the original one was about 1.6 kw I believe, I hasn't made a great deal of difference but it does start quicker.

The higher power starter will only give benefit if the battery is good, it could cause the voltage to drop lower than the lower powered one thus reducing its efficiency.

Modern starters have a small high speed motor and a reduction gear, the grease in this can dry up causing sluggishness, you can take the starter apart an lubricate it which usually gives an improvement.
