01 Boxster Base: Grinds on 3rd gear shift over 5K RPM

I guess I'm the only one in this group that doesn't speed shift. Are you telling me you don't take your foot off the throttle when you depress the clutch pedal to change gears? No wonder clutches wear down in 50k miles.

I do enjoy driving mine hard from time to time but I still don't speed shift. I bought mine to last me a while.

I just had a similar problem shifting from 1st to 2nd. It ended up being the motor mount that caused the problem. The rubber goes bad on these things with age. Start with the easy stuff the other guys described first. The syncro is the last thing on the list of possibles with the gear oil change (should do this anyways if it has not been done in the last few years) easily telling you if this is the issue. Good luck.

Why is 5000 way too high and why is 3500 to 4000 ideal?

No one said anything about speed shifting... The OP was clearly talking about executing an up shift from second to third above 5000 RPM.

Ok! Maybe I better try letting the engine rev to 5,000 rpm's before shifting from 2 to 3rd! I just didn't want to push it too hard..but it looks like these 2.5's can handle it by the many posts I'm reading.

it can handle that and much more

Conventional wisdom is that you SHOULD give it some high rev driving form time to time, its good for the engine
