964 VIN Plate + Engine Case Nr
Eyeballing a 964 and like to cross check something here:
Does anybody have a reference image for me, taken from underneath the VIN plate in the front trunk.
Especially looking how this plate is attached to the main chassis. If you prefer, you can also send it direct to me:
ivo@porschedriverslub.com
And while i am it ....
Engine number is on he right side, next to the fan housing. Check.
Is there also an engine number on the bottom of the cranck case, on the right hand side like with the 996 GT3 / Cup and 997 GT3/ Cup cars ?
Thanks a lot in advance

The 964 engine does not have serial number in any other place than next to the fan. If it is a US spec they would have a vin sticker attached to the 89 and 94 MY cars. AFAIK the only other identifiers are a 3 digit markings on the top of the case which should match. Unfortunately Porsche no longer offers engine serial numbers on CofA's as they did in the past.
Here is a Japanese import Cup car (same for all models) Notice the silver plate. This would be black for most other countries AFAIK. I am fairly confident that this plate was removed for paintwork and installed after.
This is a US Spec Cup car. You can see where the RoW vin plate would attach. The rivets are the standard size used on all 964's no matter where they were exported to and all should have them in place. If they are painted it would be a clear indication of paintwork. Not sure why they installed them on US spec cars but they did.

Helpful to know there is only one place where the engine number is.
Chassis number:
I actually mean the plate / chassis part that is sitting on the bottom, in front of the fuel tank.
Thanks again
I took these from a car i was eyeballing back then. Had to adjust the image slightly to be able to see it correctly.
Seems the welds are ± 0.5 cm (0.2 inch) in diameter and properly slammed into the chassis.
The weld points seem to sit a bit deeper into the metal.
This all makes total sense.
Unfortunately this is not like the 964 RS i was interested in.
Attached the (i think) correct way the VIN plate is supposed to be connected (top and bottom)
For clarity: This VIN is NOT the VIN doubted.
Thanks
