rebuilding drbrian's 3.2l engine

sorry the pic when zeroing the micrometer is a bit blurry...

[rcw911rsr]

we measure everything at the ideal temps to make sure it is as accurate as possible.

[rcw911rsr]

next up are the rods, the big ends first.

[rcw911rsr]

now the small end.

[rcw911rsr]

individual rod weights.

[rcw911rsr]

now the big end.

[rcw911rsr]

and the small end.

[rcw911rsr]

these are the weights straight out of the box from carrillo. i will massage them to close the gap but less than 1 gram difference is pretty awesome out of the box!

[rcw911rsr]

here are the piston weights. i also weigh all of the circlips and rings. they all weighed the same so not posting a pic of each one of those.

[rcw911rsr]

here are the wrist pins.

[rcw911rsr]

now that everything has been weighed we can start to balance each assembly by mixing and matching individual parts based on weight and then removed weight only from the parts that need it.

[rcw911rsr]

here are the rod small ends.

[rcw911rsr]

rod big ends.

[rcw911rsr]

overall final rod weights. i call it done with 2-3 tenths of a gram difference as there is inevitably more or less oil on each part in the eng. imho zero zero is eyewash and like a peeky dyno sheet, it is something to brag about but not very practical in real life.

in the end you will see i get everything where it needs to be.

[rcw911rsr]

here is the final weight and orientation for each assembly.

[rcw911rsr]

can you tell which rods needed massaging?

[rcw911rsr]

i had the crank, FW, PP and front pulley all balanced separately down to 0.3 grams so this motor should run smoothly and rev freely!

Sometimes tables and charts work better than photos.....this is one of those times.

id be happy to provide a chart and/or graph if you could be more specific. i think you would like to see a spread sheet with all of the individual weights in separate cells with totals at the end; but want to make sure before i spend time on the wrong chart. maybe i'll make a pivot table.

i actually have always loved using excel so just let me know what you are looking for.

we got the perimeter bolts in and im working on clearencing the oil pump and nearest carrillo rods to make sure there is no chance of contact.
