Cup - engine number?

Hi,

I have an engine number from a car and it is supposed to be a cup engine.
But I can't find the same number series in the books I have. Can anyone confirm the number?

62M20030**

It's the fourth digit (2) I don't understand, because in the books I have there are only zeros after the model year letter. The number 30 would fit within the 120 M-series car that was built. I also can't see any difference in the serial numbers between a Row C2 and a Cup engine in the same books. Is there a way to identify it as a cup engine?

Cheers,

Thomas

First digit = number of cylinders (6 cylinders)
Second digit = model type (2 = normally aspirated engine)
Third digit = year number (M = 1991)

Followed by 5 digit serial number 00501 to 20000

Digit 4 was originally for Tiptronic models.

RS numbers are: 62N80001- 82500
 
Look for the type number on top of the engine case to the right of the fan and not the engine number on the side of the case by the fan,should help
 
It's says M64/01 but isn't that the same as for RoW and Cupcars?

And if the first number (2) is a part of the serial number, isn't it very high then (20030)?

I'm asking about this because I'm trying to clarifay what a friend of mine has bought the real thing or not. The seller said the engine was from a cup-car that was written off.

I can confirm it is a cup engine looking at my car and some other M series Cups.

The 2 is not related to the no. they all have it.

62N20034

62L20047
 
OK, great thanks for that confirmation!

I'll see if I can find any info about that old car. It was a French racing team that had the cup car but they crashed it or crash/fire so they moved all the parts they could use to a C4 body. They then raced the "new" car before it was sold to Germany where we bought it.

Thanks,

Thomas
 
Yes, '91 Cup cars had engine nos in the range 62M20001-62M20120. VIN nos were WPOZZZ96ZMS409001-09120.
 
Re numbering a spare case is easy to do !The type number on the top is important for motorsport engines.Most people forget about these type numbers or do not know that they exist.
Lots of spare cup engines also made,so may not tie up with a chassis number
sounds like all the numbers are good
 

ORIGINAL: 964RS

First digit = number of cylinders (6 cylinders)
Second digit = model type (2 = normally aspirated engine)
Third digit = year number (M = 1991)

Followed by 5 digit serial number 00501 to 20000

Let me mention a few things I learned over the years:

M64/01 says that engine is for manual gear box

M64/02 says that engine is for tip gearbox

M64/03 says that engine is a RS engine

I have no clue about the differences of the engine cases, if there are any at all.


As Paul states above the engine serial numbers run up to 20000. However, all the Cup engines I know have engine numbers higher than 20000. A former team owner told me, all the Cup engines were specially built, no surprise.

That engine in question could well be a Cup engine.

The best evidence would be the Wagenpaß of the initial car, where the number of the original engine is listed.

Anorak time now,

Just to clarify there is no VIN engine match up. Some earlier VINs have later engines and vice versa.

Right, Charles. For the Cup cars it all comes down to the "Wagenpaß" document, if you want to be sure - or the Porsche "passport", but I´m not sure, if it´s available for Cup cars.

Hacki, I guess the issue is that if the wagonpass is now long lost and forgotten, then there is no knowing.
 
Porsche motorsport should be able to tell you what was with what.
They did with my 993rsr,engine and box numbers etc,at first you must show that you own the car/chassis number,they will then help you.
I doubt they would just research a engine number though,if the numbers are correct on the engine, does it matter if it was in a car or not,a cup engine is a cup engine.
Top teams would typically have 1 or 2 spare engines with them at the track etc

Today I talked to the guy running the Porsche factory archive. They don´t have records of the Cup cars from 1990 and 1991 themselves. It all starts with 1992, the older records were lost somehow.
I hoped to get some extra info or pics about my car, in the end I sent him some documents. So much about the archive[:mad:]

Rgds,

I can absolutely confirm this statement.[;)]

Seriously: Once they (Porsche factory) are sure you are the owner, they will do, what they can.
 
" Due to legal reasons I cannot provide you with the engine and gearbox numbers so you have to contact your local Porsche dealer in order to have these details confirmed. "

This is what I got from PorscheAG. And Reading were a joke. They will not supply year authenticity for the Cup for road registration! It is flagged on the computer as modified( Cup spec).

Very helpful to PCGB Club member! NOT.

Maybe VW will be more helpful!
 
sorry to hear they have lost the records,not good for the factory to do that.
I will be meeting the person in September who looks after the archives,as he is coming to the uk.I will see if they will let me go and have a look through the motorsport dept for the records,i bet they will be there some place [;)].We can but try and get them to find the records!It would be a shame to lose all that data.
Legal reasons for not giving info is usually data protection,but if you send them proof of ownership,they can spill the beans on whats what as long as you own the said car,which can make things difficult when you are researching a car before purchase.
Just found my old 993 cup car data,that came via PZ Munster,must send it to the owner Phil.
 
And to prove ownership you need a V50 for which you need the details from Porsche,

Round we go again!

Catch 22..................
