Engine number doesn’t match hood sticker

[GH996]

I should have included the numbers in the original post, my bad...

Hood sticker says: 66X69600
Perimeter says: 66X06108
Engine stamped: 66X15987

I’d really like to know when that engine went in service and what model variant it came from.

Thanks,

On my1999 hood sticker, it reads 66X for the engine and G9600 which is the transmission type. I don't think the engine serial number is on the hood sticker.

Wow, thought all original engine s/n were printed on the hood tag. Mind taking a picture and posting? Thanks!

I could be wrong but I don't see it.

It's there. (see picture)

Hard to make it out, but it looks like - M96/01-66W-G9600-00

This means your motor was manufactured early in 1998.

The next thing you'll want to do is match that number with the serial number that is printed on the motor.

You maybe onto something regarding that middle number being a trans code instead of the serial number! You have me thinking now. Gotta look that up!

Here's my Frunk tag....

Looks like mine actually is - M96/03-662-G960-10

Maybe that third set is supposed to be "G9600"???

GH996 for the win!!!!!

This is why I love forums... we all work towards finding the *correct* information.

Check it out...

Here's mine decoded:

G - Getrag 6-speed manual transmission

96 - 96 trans series

00 - Sub type "00"

1 - Open Differential

I found this on the PCA site when somebody asked the same question.

The sticker on the hood tells the engine and transmission code, that is, what TYPE was being installed when built. It does not show the actual serial number of either one. Those only appear on the engine & gearbox.

Based on *NEW* information pointed out by GH996, here's what I think based on your information shared.

One, your hood tag number "66X69600" is actually 66X - G9600 which means a 1999 motor with Getrag manual transmission.

Next, Perimeter Porsche states that the original motor installed had a Serial Number of "66X06108". This is coming directly from the serial number stamped on the *original* motor installed from the factory.

Finally, the current motor in the car is "66X15987" which really means... You had ONE and only ONE engine swap.
