But in reality its not that easy.I was rebuilding one crysler 2.2 bottom a year ago.Difference in piston weights was over 3 grams! Where to take that much material off? And worst case was, all were more or less close, and one was lighter than all other in more than 3 grams.Clean, not worn, stock turbo mahles! Have done them in 1 gram.Guys from local shop claim they should be done to 0.02gram! Similar story is with rods, crank, flywheel. Flywheel they balance here only up to 6000. For us its ok, but for suzuki its a half of rpm.

The more balanced it is, the higher it can rev to a point. Most import motors have bearing surfaces alot smaller than we do. They have alot less drag, plus they have a shorted bore/stroke ratio where as we have a long stroke and butt loads of torque. Darrell Cox runs his SRT4 up to 10,000 rpm, so I am sure with the proper balancing, our motors should be able to hit 8,000-10,000 too. Your gonna want some light weight parts in there.
