911 3.2 motor number issue

[kristof101]

Hello everyone.

I recently purcashed a 911 3.2 that was previously registered in my country, but originaly it was a US car.
I run into the problam that in Hungary a COA is requirement for it to have a license plate.
My car however has an overstamp on the second digit of the engine number. The engine number is 64K02*** and on the second digit there is an overstamped 3 on the 4(or the other way around). The car was succesfully registered in the Netherlands, Austria and Hungary before with this issue that I know of.
The car was in use with this problem for at least the last 10 years. It was printed in on all of its previous documentation, however now the exam place refuses to pass it since it has been tempered with.
My questions are:
why would anyone temper with the original destination country? I don't see any upsides to this?
Is it a possibility that this is an original factory error? Has anyone see anything like this before?
Is there any way to get a COA for such an engine?
Did they stamp the engines separatelly for US and ROW meaning: does a 64K02*** and a 63K02*** exist or the serial itself is unique and either one exists but not both?

+1 the car is not matching numbers (it is an '87 car and this motor is an '89) so I cannot get a build sheet or a PPS
Any insights would be helpful.

(In reality the 4 seems to be the dominant number but not on this picture.)

The fact is the car already been to an exam place and they told me that given it has been tempered with they do not want to take on the risk of passing it.
They fear that the overstamp is because som shady thing and they pass it it can be a legal issue.

IF its a "63K" it an 89 3.2 (170KW) if it is a "64K" it is 89 3.2 with a catalytic converter (160KW).

So the "63" were euro/ROW and the "64" were North American. That is just from a quick search of our library.

Cheers

Thank you guys.
The problem is not the fact is was originally designed for US or ROW.
The issue is it doesn't have a COA since its not original in the car (car is '87 motor is '89). If not documented properly, in Hungary it cannot pass the exam for license plate. For us a COA or proper papers for the motor change is obligatory. The reason it was discovered was the number issue, but this is also why it is harder to get papers for it.

I think what would be nice to know if the numbers after the letter lets say 6*K02222 are unique numbers in the K year or did they count the regional motors differently?
Were a 63K02222 and 64K02222 produced or just one depending on the original destination country? If both exists I think I will have a really hard time getting any certificate even from porsche itself since I dont know which one I have. (CAT and a slight difference in compression wouldn't tell the story since they could be altered later) Basically as far as I know the motor block itsel fis identical and the difference is only in the assembly as the whole ICE/ unit.

what is the number 930/ ??

the rest of the 5 numbers is just serial number....

it is strange as you say ,the car was driving registered in Hungery past 10 years and you need extra documentations?
i`d go to a different place with the 911..
