It's more the pistons than anything. The crank and rods are not your limiting factor, but that low end forged alloy in a piston leaves little room for error. Upgrade the piston to a 2618 alloy, and I'd put it to work at 1000 all day assuming everything else is up to task.

Je, cp, anything that's 2618. Who are you getting this from? What piston options do they have?

Wiseco really makes a nice coated piston nowadays. If you can try and stick with them in a higher strength alloy.
