Part Number Confirmation Nur Pistons

[ZimNismoBoy]

I received 6 new pistons today from the couriers and i have the part number on the side of the box.

From what i can tell in the fast system they are Nur pistons .

But its all jibberish.

Please can some else help me out and set my fears at ease.

Part No A2010-AB000

Piston with pin assembly.

Cost was $ 810 usd for a full set

Keep in mind im building a Nur engine .

The pistons arent shiny and have a mat finish .

Almost like they have been heat treated.

are they meant to be forged or something? what clearances do they run?

[ZimNismoBoy]

from what ive been told they are stronger then stock and can take more Bhp per piston .

But i needed to know if i have the correct part numbers for the build that im doing .

Should i have n1 pistons or nur pistons?

with the above part number ?

please help me confirm

As far as I'm aware, N1 pistons are cast. There shouldn't be a difference between Nur and N1 pistons, since the Nur R34 GTRs have N1 gear (block, pistons etc)

i thought so too... but in the nissan fast system you get Standard pistons, you get N1 pistons and you get Nur pistons .

I always thought the N1 pistons were the Nur pistons but appears not based on the difference in part numbers.

And for sure they are different in the nissan fast.

ABO stands for Nur on most of the lables i have seen based on a Nur engine.

the Tags for nur engines have ABO on them as i received a nur spec engine and that had the nissan tag with serial number etc.
