Just wanted to share my experience replacing my starter yesterday in my 2001 Porsche Boxster base with novices like me. One poster who commented about this job on 101 Projects for Your Porsche Boxster online said that it was impossible to remove the lower bolt where the ground strap is attatched without using a long extended rachet through the panel behind the seats.
Well, after removing the throttle body & connected T and gently moving the oil filler half section that runs out of the trunk toward the passenger side rear tire I was able to break loose the bolt using a 15 mm straight racheting Goodwrench. I am no mechanic, but am slowly learning to do a few simple jobs from this forum and the Pelican book. The starter replacement took me an hour and a half in total being very methodical. It was a triumph for me considering some people's experiences.
Working on my car is a labor of love even though I get frustrated with my limited expertise due to the attention my Boxster needs and certainly deserves. As soon as I get a Power Bleeder I'll flush the brakes and then replace the heater core because I smell coolant through the cabin vents with AC or Heat on.
I've had many treats in life. but looking back at my 61 years most are not as gratifying as my 13 month old relationship with my 81K mile Boxster. Happy trails.
