996 Engine part code?

[SY996]

Hi, my 996 had its engine replaced in 2008, and the part code given is P996.100.995.DX. Could anybody tell me what kind of engine this is? For example; is it an exchange engine, updated, newer model year, etc.

Thanks in advance!

Hello, if you post your engines serial number, located on the side of the engine oil sump plate (near LH rear wheel), we can decode the information for you.

I've found this off of the Porsche parts list:-

Can anybody tell me what this means?

Just what it says... it is a replacement engine for MY2005, 3.6 liter, 320 HP.

Your engine serial would tell us a little more about it's original manufacture date (but not it's rebuild date).

[SY996]

The serial code on the side of the engine is 996 104 63 78 R.

Edit: After doing some more research it looks like this isn't the serial. I'll have another look.

M96/03AT66567460

That engine was originally built in 2005.

And the AT tells us that it has been rebuilt.

The 67460 is just a sequence number.

And the M96/03 tells us it is a 3.6L 996 engine as Loren pointed out several posts up.

Thanks. So what are the differences between this engine and the first of the 3.6 997 engines?

Probably very little differences. The IMS change did not happen until mid-model year 2006.

My 05 boxster vin doesn't match the engine serial # m96/2561504112. can you decode for me?

I do not know what you mean "does not match".

Your engine serial number says the engine was built in 2005 -- the same year as your car.

It could have also been replaced that same year with another engine - but that is a new engine serial number (not a rebuilt).

Actually, the non serviceable IMS began to show up in model year 2005 (the only way to tell which one is in a 2005 it to take the car apart); all 2006's have it.
