If the service book is there, it has a option label in it. You can also take the vin to a Porsche dealer and they should be able to print you a build sheet which has all the options and original price

If you go on Rennlist, you may be able to find someone local to the car to do a Rennfax, which is someone taking a good look and test drive the carand give yo their opinion before you make the joiurney.

As an FYI, just because the IMSB was replaced, does not mean it will be problem free. Even the LN bearing has had failures. Yes, that is documented by statements from none othere than Charles Navarro, owner of LN

Now in fairness, often those after replacement failures are due to improper installation or failure to properly inspect and clean an engine that had an IMS failure or other crap in the engine that caused the replacement bearing to fail. But in any case, replacement IMSB have and will fail. The only one that claims ZERO failures is Jake Raby @ Flat 6 Innovations and he does a very extensive pre-qualification of an engine BEFORE he will do a replacement and has stated he rejects a lot of engines. He only will do a replacement if it meets his strict standards no matter how much money you try to throw at him. Most others don't come close to his level of inspection. Just because a shop can buy the bearing and slam it into your engine does not mean you wont have problems

Hopefully your thread will not be hijacked by those that think the LN or other bearings are infallible.
