With 84K miles and a Tip I would not change the IMS or do any extensive non-essential work. If I had a manual AND it needed a clutch I would change the IMS at that mileage. There are MANY (20+) mods of catestrophic failure and the IMS and timing chain and related components are only a few. You would be spending around $4-5K and still have an engine with a limited remaining life. For my money I would save that $4-5K for WHEN it does go boom and put that toward "your next Boxster phase." I think it's time for you to come to grips that your engine will not last forever and have your plan for when it does. Even Jake does not recommend replacing the IMS at that milage….
