Aside from money, what about the IMS replacement is going to delay you getting on the road? You said it would be weeks before the transmission would be reinstalled. You have time to determine which bearing is needed, what your replacement choice should be, order it, obtain the tools, study the instructions and do it.

~4 years ago, with single row engines that were up to 11 years old, the failure rate Porsche knew about was around 1% per year with surely more failing that were junked or repaired outside Porsche's knowledge. It is now ~4 years later than when those statistics were first presented to the courts. The average Boxster has gone through another owner in that time. And more miles and more unknown or undone maintenance. So the probability of a single row failure is much higher now but then again the probability of failure for all the parts is also higher.

So it comes down to are you willing to spend to fix this potential problem when all the other potential problems may, taken together, have a higher and increasing chance of taking out the engine before the IMS does?

As these cars become almost cheaper to replace than repair, this becomes a more difficult decision.

Good luck in whatever you decide.
