If you want to run a HUGE shot then a custom N2O piston with the top ring land farther down from the top of the piston is the way to go. We are talking about over a 300shot here.

Most times guys kill pistons due to the two things I mentioned. If you build the motor with this in mind it's really not that big of a issue.

Thanks for the info.

CNC motorsports has KB forged for $340ish, these are flat top with -4.7cc reliefs. Are the cheap KB any good? Anybody know of a killer deal out there??
how much do you plan on using the n20

.300 down from the top ring land. Hard to find rings that are that thick.

That's a serious N2O piston right there.
