Is the engine number you have on the microfiche records? And does it say it was originallyfitted to the car it is in now? If so, it is easy to put 2 and 2 together and realise what has happened! Someone (not you) might be in a little trouble....

Really like to see this outcome

[yel327]

Did this ever get resolved? The duplicate engine number I mean.

I reckon the engine number in this pic is the real deal.

9G3 single cast date.

Surely someone knows something of the XU1 in Pinaroo or Adelaide that has JP390021.

Anthony?

Hi S Pack,

I have seen some photos of the 390xxx engine fairly recently, it is not the other 21. However it is also a dual cast 4g3 engine.

21 was advertised in unique cars in the mid late 90's for around 6k in Darwin ( I would have liked to purchased the car). It is also listed as PO xu1 on a Porsche forum.

Cheers

Both JP390022,and JP390023 are dual cast 4G3............................... why is JP390021 NOT.

before it was for sale in the NT, it was for sale a lot early in SA mid to late 80's

So, the car was sold in SA in the 1980's and moved to the NT. Lots of cars get sold and moved interstate, nothing new there.

The car was sold in the NT minus it's engine & gearbox and now resides in SA and has magically been reunited with JP390021 even though the original JP390021 block from this car resides in another state.

 

Why is the original JP390021 a single cast date block when some of it's siblings are dual cast date? You will have to ask GMH why as GMH built these cars and only GMH know why they used single cast date and dual cast date blocks concurrently in these XU1's.

I am confused.

 

We have three engines being spoken about with consecutive numbers. Putting the dual cast debate aside why have two got a cast date of 4G3 and one a cast date of 9G3.  Cannot understand how GMH would number the first engine from a casting five days later.

[peterd]

definitely not

That is simply the randomness with which GMH used the castings. Just like how the engines were randomly installed in the cars. Nothing was done in any consecutive order.

 

This random nature shows up in the very 1st JP engines. The cast dates of the blocks and the engine number sequence are not always in any logical order.

Why would there be two engine blocks with the same number stamped nearly identical if the original exists ?

Just wondering how you know the car was sold minus the engine and gearbox in the NT is correct? It was a long time ago.

Do you own or know of this XU1?

[peterd]

I agree with the randomness of engine selection for the cars. The August production cars had July casting dates and the engines would have been stockpiled at Woodville and Acacia Ridge ready to go in.  If you look at it like this then the last engine assembled could have been one of the first used as that was probably how they were laid out but I have only ever seen 4G3 and 5G3 engines in the August assembled cars never a 9G3. Given there is lots of evidence of both 4 and 5G3 engines in these cars I would love to know how many other 9G3 engines are out there in these cars. 

[jb873]

No to both, other than what I have stated. But you appear to have a connection and I was interested to know, as the alleged engine/gearbox removal happened along time ago.

I also think it would be interesting to see if there are other 9g3 engines.

Just curious, that's all.
