Help Identifying Rb30 Pistons & Rods?

[HR31-PASSAGE]

Hey guys I sprung 1 main & rod bearing in my s2 rb30 so looking to replace them as they have heat damage

Now I've found afew rods to replace but they have different numbers stamped on the side of the rods, is there any difference between turbo & non turbo rods?

Can anyone tell me what my rods are in the picture attracted?

Also can anyone tell me what my pistons are in the picture attached to please?

Cheers

Both are stock RB30E rods. The last number on the rods indicate the size (more so the tolerances) of them. The '2' on the piston is the same thing again. When the blocks were made they had to allow for tolerances as not every block can be made absolutely perfectly sized as all the others. So each piston has a 0,1,2 or 3 stamped into it. Each number represents a certain size out of tolerance, or a different tolerance bracket. Have a look at the top of the block next to the bores and you will also find a number stamped into it. The block and piston numbers should match for each cylinder.

ok makes sense now! although all my other 4 rods have the same numbers stamped on them as the bottom rod (1) does this matter?

basically so if i pick up another rod from another engine it will be fine to run with my other rods yeah?

so long as the tolerances are good just throw it in and rip skiddies

edit: did you say you're fitting fresh bearings?
