Remanufactured engine upgrades??

[teleski]

My 2000 base received a remanufactured engine in mid 2005. Serial # is M96/22AT65Y65075. Supposedly the reman would have used the latest available part upgrades for that block and head. I know that they went to the single row IMS bearing at the end of the 2000 run, and at some point the cam chains and sprockets were redesigned.

Would anyone happen to know what would have been used in this engine? Any other 2000 remans out there? Porsche was unable to give me any more specific info and I would rather drive it than tear it apart out of curiosity!

Most likely, the replacement engine has the non- servicable IMS bearing in it. The only way to know for sure is to look at the IMS center bolt, if it is 22MM, that is what you have.

The cam chains did not change. The chain from crankshaft to IMS changed at the same time that the IMSB changed to the 1st single row design.
