No, the engines ARE the same, only the IMS shaft has been changed to the updated version. But if it makes you feel better, be my guest.....................

They're the same but depending the build date, you can or cannot service the IMSB. Ooooookay.

You can tell them what you want. I just wanted them to know that, if they intend on replacing the IMSB, they MAY NOT have same type that originally came with the car. And, if they've been following, I'm sure they understood.

Which is why it would be THEIR responsibility to find out what they are dealing with before they order parts they may or may not be able to return.............

....because it's not always the same. If it was the same that came with the car they wouldn't need to, would they? Just sayin'.

Look, ALL the necessary information about which type of IMS could be in the engine is readlly available to ANYONE that takes to time to look and do some reading. If one choses not to do that, mistakes can be made, but not because this is some kind of mystery, it was by choice........

Boy this has gone way off tangent.

They actually DID take the time to come here asking for information, and I wanted to make sure they don't walk off with the misconception that the AT engine is always exactly the same. It's not. Even you, in a roundabout way, have admitted that.

Not everybody has the resources to look up engine serial numbers. Not everybody even knows that they SHOULD, especially for certain procedures, and specifically for the IMSB.
That's why this forum is here: To INFORM people, not misinform them.

I thought my AT engine is the same as the original because I believe I've read on here that they are. It's not. And I don't want them to make the same mistake I did.

As I said before, I don't want to argue with you. Peace.

Fine. I think we all see your point. ...but why do you own a fire truck?

You're talking about parts matching, and that's an important and valid hint. The stupid thing about these AT-engines is that the standard parts catalogues may not be valid. The only good thing is that you (mostly) get an updated unit in parts. But there can also be weird things in these motors, I am quoting from an engine rebuilder:

"Due to production problems, the first 2.5 litre boxster engines had some engine housings in which the cast-in Lokasil mouldings were mechanically removed after casting. New cylinder liners were then shrunk in. Some of these engines subsequently had problems with cylinder liners shifting downwards towards the crankcase. At some point, the liner had moved so far down that the top piston ring jumped behind the top edge of the liner. This of course led to
engine damage."
