These Stock Pistons? This A 26 Rod?

[femno]

Hey just looking for a little insight here....

I pulled apart my 26 today, just wondering whether these are stocko pistons or not.

Also, one of the rods is diff in terms of the numbers on it, need to know whether this is a 26 rod or not. The one on the left is the odd one out, its also a little lighter in colour compared to the others, and has grounding marks on it for balancing.

Thanks for the help!

There are some pics of stock BNR34 rods and pistons in my for sale thread (see signature). Not sure if there are differences between 32, 33 and 34 though.

they are n1 pistons and are .5mm oversize. the rods may have been balanced.

standard rods

standard rods

Yeah i know theyre standard but is the odd one out a 26 rod and should it just be used anyway?

Edit: theyre not physically different, its just the numbers that are completely different.

Thanks alot for the intell guys.

Anyone got some n1 pistons for sale?

[T04GTR]

they are batch numbers. the "o5u" is the common denonomator. from the look of it its a typical buget jap rebuild. n1 pistons with some standard rods. hows the crank?

more than likly its sufferd a spun bearing and been rebuilt fron a parts bin. nothing wrong with that just yeah..

pull the rods off and weigh them

Didnt get time to pull the crank out today but will do and inspect it tomorrow.

Yeah the crank has extra grounding and drillings, it looks as if it has been fully balanced.

With the rods i was thinking it could be a 25 rod or something like that, as gtr rods are used as upgrades etc etc...

Thanks again T04

If theyre 0.5mm oversize you would use them to replace stock pistons if say your bores were badly scored and needed to be cleaned up and bored out.

They are both Rb26 rods , looks like at some stage the changed one ( different batch number and probably newer) so the lighter colour . The pistons are stock Nissan N1's ( 24u mark on them) but they are 1mm oversise so 87 mm bore ( thats the 100 on them near the dot that indicates the front of the piston ). 50 is .5 mm oversise and standard size have st there ( or something like that ).

Here is a pic of a complete set of rods that are the same batch .
