what's the difference between the 99 and 00+ 996s?

If the engine is replaced off 01.06, you will have the latest update, inclusive reinforced intermediate shaft.

how would you know if the update is 01.06? i believe it was replaced in 02 or 03. also is there a positive or negative to having a traditional cable driven throttle vs. a egas? i have had a 97 boxster and a 00 box but didn't notice too much of a difference..

Very interesting comment RFM. I have a 2000 C2 with a new engine that was installed in Aug 06 (engine# M96/04AT66Y66186).

Can you confirm if mine also has the updated IMS and whether Jake Raby's IMS bearing retrofit would make sense in my case?

Joost,

The replacement engine in your car have the latest up date, IMS, seal, crankcase bolts, bearing and larger retaining bolt + nut. This engines are good so far, they have still to prove their quality on long term but Raby's construction also IMHO.

"Hartelijke dank" for your comments, and you certainly have a point there regarding the reliability of both designs...

Do you know how these late M96 engines differ from the early M97, that I hear had their fair share of issues in the 2005 997's?
