Help to identify RB26 motor by the identification ID

[filluptieu]

Hello fellow RB owners,

Can someone please help me identify this RB26 ID number on the block?

043825A

If the block has 05U embossed on it then it's a run of the mill rb26. All the same.

If it has 24u its an n1 block. 

You'll find the markings on the exhaust side under the welsch plugs... near cylinder 2.

Im trying to figure out if it's an r32 or r33. Is there a way to tell from the block Id stamp?

Not that I am aware of. I don't believe that there is any record of engine numbers for specific chassis. Nor am i aware of changes to the numbers that would indicate the time of build (happy to be proven wrong by the wider community of course).

Allow me to correct myself. A quick google: "RB26 Build Date" brought up this thread:

This may be of some use to you.

It's from a late R32.

Thanks David! Can you please help me understand how you determined this?

[GT-R David]

Had a picture on my computer with some numbers. Downloaded it somewhere sometime, can't remember where. Tells the engine starting numbers for R32-R34 by year.

Do you mind sharing that list?

Also if anyone has another list as well. Just trying to fact check as much as possible.

After a ton of research, I am still having a hard time looking for it and figure others could really use it as well.
