Worthwhile 3.4 upgrades while the engine is out

[steve_wilwerding]

I'm about to swap a 3.4L 996 engine into my Boxster and I'm wondering what changes/improvements to do while the engine is out. I figure at least plugs and a poly belt. Any other suggestions? Is it worthwhile to swap out the AOS? How about oil baffles, as I plan to use it on the track?

Plugs, tubes, water pump, underdrive pulley, low temp thermostat, all new tensioners and rollers, oil pump..... Im sure I can think of more.. I have a 3.4 in my box too :)

How about a new air/oil separator, too?

You should upgrade to LN Engineering Intermediate shaft bearing and replace RMS.

Depends on what year the engine was built though. I have a replacement 3.4 in my 2000 996 with 50K hard miles on it now, and still debating whether I should do the IMS bearing upgrade next time the tranny or engine is out.
