I let you know my experience with this issue on your ecmlink forum thread. The noise has come and gone a couple of times for me. I got rid of the noise and I never changed starters. I just changed the starter circuit harness (frayed and corroding ends on my original) and put in a new battery.

I have a friend with a 1g and his always had the grinding/scraping noise while cranking. Eventually his starter went bad and he had me throw in the new one. We were both excited to see if the new starter would cure the noise while cranking, it did not.

Have you checked for voltage drop on the starter circuit? Also measure the voltage drop across the solenoid. Voltage drop test the whole circuit, so don't forget the ground side (starter case back to neg terminal). And remember current has to be flowing for resistance to drop the voltage, so someone has to be cranking while your testing for voltage drop (excessive resistance). Rule of thumb is no more than .2v of drop per connection or .5v per cable.

Make sure the ground cable that goes into one of the trans bellhousing bolts is actually through one of the starter bolts.
