Is this a NUR or STD block. Pictures inside

[NismoS-tune]

Won't get into the story but here's what I'm after. No opinions please, just facts so I don't get confused.

Here's the block tag (05U) Normally known as Standard block.

Here's the serial number location though there isn't one and it doesn't look like it was modified so to speak.


Here's where I may be confused. I thought the Nur engines were ALL N1 blocks (24U) but I was told this is a Nur block, something about having no serial number which in my mind all new blocks come with no serial number meaning this would be a simple standard block which didn't come in a car? Anyone know the facts?

Thanks.

That would be a Nissan replacement stock block.

My RB20 block came with serial number under RB20, so perhaps you're onto something! interested to find out as well.

Won't drop names cause it's private. This is my new engine that's been gone over a year. I traded my good long block for a bare Nur from what I was told to help me decide on the exchange. Trying to see if it's a nur or just sometime I shouldn't have done as I wanted a stronger block...

Standard block. My Nur block has the 24U stamp.

well then. I guess I should have ensured this before having it completed . soo what, my engine isn't that strong then I guess.

N1 block is overrated anyways, it's what's inside that counts.


Your block is STRONG Franc!
