My next engine waiting to be swapped in...

Bare in mind that Tom drives the crap out of his Boxster. It is a race car and he does a lot of the work himself
Having spare engines and transmissions ready to go is not that uncommon for a race car.
That all being said, if it keeps you up at night, replace the IMSB. There are several choices including the LN ceramic as well as a few roller bearing ones and some with oil feed. Lots of different flavors of Kool-aid to choose from.
My 01 S has 87k on the original IMSB, I do a bunch of autocross and around 10-12 track days a year where I drive it hard. I change the oil every 5k or >2500 if going to the track. I sleep well at night and at some point I will probably change out the IMSB
YMMV
