I'm almost done with converting my 3.8 engine to fit into the boxster, finished engine wire harness last night.

Only things missing are new connections for the air/oil separator, waiting for hoses and small parts shipped to me next weekend.

I noticed some differences to the 3.6 conversion described by Wayne, will try to summarize once I'm done. Generally, it's less differences in my 987/997 conversion.

Small vacuum hoses - less, just one resonance flapper valve instead of two

I'm not entirely satisfied with the power steering return line solution...

The air/oil separator is in the way, it is located in a different location, exactly where the power steering return line sits, there is a sensor in that place on the 987 engine instead on top of the case.

Anyone came across that issue as well yet? My current solution is to cut the line and extend it a little bit with a hose so the line runs between seperator and oil cooler..
