With respect mate if you do not know the answers to your own questions and I am guessing you don't or you would not be asking, then a self build is not for you.
The VQ35DE requires specialized knowledge to rebuild these motors properly.
These are 11.0:1 CR pistons and the are +50 oversize.
They are suitable for 96.000/96.020mm bore size.
I do not think that they come with rings as the seller would have said so, however his contact number is in the listing and I am sure that he will clerify if you give him a ring.
