Rb26 N1 Block Id?

[Andy D]

How do identify a RB26 N1 block while it is in the car?

Have already tried searched the forums but came up empty.

Cheers

Should have "24U" stamped on the exhaust side of the block near the front turbo. You will have to get under the car with a torch probably

Normal RB26 will just be "05U" from memory.

Is there any way to check by just looking at the engine number?

Also did any models come out standard with N1 blocks?

[rinmak]

Yeah, N1 models came with N1 blocks standard

And AFAIK there is no way to tell via engine number

Ah ya beat me to it, LOL!

Take down the Chassie number and build plate and post in the VINS You Wanted Fast thread and a member will decode it for you.

Probley the safest way.

Hey Mate,

Been through this in the last couple of weeks myself.

My car is an 92 R32 N1 GTR, confirmed through Nissan Fast and i have log books for the car up to present. I have had the car inspected and there is no evidence what so ever that it has had an engine swap. BUT it does not have 24U stamped on the block.

Unfortunately i wasn't able to find anything definite that say 100% ALL N1's were stamped with 24U

I did however remember reading something that stated later model N1's were only stamped with 24U and being a 92 model R32 in my case it was the first "N1" release. The reverse is that everyone i spoke to, had no doubt that all later model N1's were stamped with 24U so if it's an R33 or R34 it should definitely have it.

If you find anything "official" from Nissan, let me know. Very interested.
