This is a question for the experienced builders. Getting ready to reassemble my stock ej255 turbo block and of course the piston/rod combos got messed up. All the pistons weigh the same and I have the 2 size A and 2 size B's sorted out. The pins all weigh the same. Two of the rods each weigh 5g more than the other two (595g vs 590g). Two of the rods are stamped with a code containing the letter A and two with B. I assume they match up with A and B pistons. From a picture I took I know one of the 590g rods is number 2. Does the other 590g rod go to number 1 and the two heavier rods to 3 and 4?
Subaru built it with these rods so I assume it's in their tolerances. Is it worth balancing all the rods to 590 for stage 3 (bnr16g with possible e85)?
