sr20det bearing problem

[ohhdude]

Hi, I have a 200sx (sr20det s14) and I have faced with bearing knocking sound. After that I disassambled the engine and;
The numbers on the crank:
1st row :
12122
2nd row:
1122
The numbers on the block:
U11111
If am i right; I have made a research and these are my numbers:
Main bearing: 23233
Rod bearings: 1122


And the rod bearing, which has found on disassambled engine,part number is 12111-1N500. I have made a research and This is a Grade 0 bearing.
Now, my questions are:
1)Is this the correct grade for my crank and block?.
2)My crank needs to be machined by 0.25mm. So i can't figure it out what bearings are needed for main & rod for my machined crank.
3)I am living in Turkey and It is really hard to find that parts. I have one option that is buying parts on internet so i have searched FRsports and ebay to find a part. But I have no opinion about these numbers?

If u can help me i will be grateful

I would email frsports about your bearing question. They help me when I was rebuilding my motor and I went with acl race bearing std size. if you go with Nissan bearing then you would need the number on the crank and block to match. Since you are going to machine the crank just get acl race bearing+.25 bearing.

Acl has different part numbers for s14 sr20det .25 bearings. I couldnt decide which one should i buy.i will send e-mail to ask Frsports to help me. Thanks for your help
