Thanks—sounds like you were in an environment that was worlds away from production cars. A good friend had a business running EDM Wire machines that dealt with the kind of tolerances you describe.
All the JE pistons needed a little massaging. Should be a fun engine and car when it’s finished.

I wouldn’t say worlds away. My parts were mostly used on helicopters instead of cars. Blackhawk, Seahawk, Super Stallion. Chinook etc. i did do vintage restoration parts used on some significant pebble beach winning cars. But those were copies i made using the original parts. No tolerances just close.
As a first tier supplier i was what they called their sliced bread shop. Small quantities and usually very complex and detailed parts mostly with tight tolerances. The mass produced parts were made by the big guys. I was the closest thing to rapid prototype back in the day. Usually mass produced parts weren’t healed to the tolerances of my parts. Or their scrap rate was significantly higher than my 2%.
i would put the connecting rod manufacture on the same level as the larger shops. My parts would be more like the vintage custom special wishes parts.

Porsche has continued to reduce weight and tighten tolerances compared to the original engines internals. The tolerances of the day limited their ability to maximize power. They learned this with the RS which used the lightest closer tolerance internals. Therefore IMO they go hand in hand. As they progressed changing (tightening) tolerances and reducing weight improved engine efficiency and power output. Today we have the ability to manufacture on a level we couldn’t do economically back in the 90’s.

yes and no. Measurements are measurements the part is designed and built to. Tolerances are the variation (deviation) those measurements are allowed and still be within spec. You can balance most any part. That is why we are saying pauter carillo etc are balance and matched with a tight tolerance vs what the factory supplied in the 90’s.

I agree there are a number of excellent products out there it all depends on what you are trying to achieve. Although @Spyerx Which Ti rods did yo use? I know the Cup car rods have a limited life expectancy.
