What else should I change while changing my engine?

[Byron in Atlanta]

Hello all....you'll recall that when we last visited, I had just blown the engine in my '02 Boxster S at a DE at Road Atlanta. Since then I have acquired a replacement 3.2L engine and have ordered the Improved IMS bearing from LN Engineering. I also got their Oil Pan expansion kit and their AccuSump oiling system. Obviously, I am hoping that these measures decrease any oiling or IMS problems at the track. I have also gotten a new AOS assembly from my local dealer and am ordering today a new expansion tank for the cooling system. I have two stock clutches and pressure plates (the replacement engine had one). I am considering an upgrade there as well.

My question to the group is what other items should I replace while I've got the engine out? Water hoses? Power steering pump? Hoses? Any recommendations on a Clutch/Flywheel setup for DE's? What about engine mounts? Am I overlooking any weak points that I should look at improving? RMS?

I want to make the car a great DE car while still being able to take it on the street. Thanks in advance!
