L92 stock botom end with nitrous
L92 stock botom end with nitrous once this 6.2 finds its way into the truck I'll be looking to spray it. The kit I have will flow anywhere from 100-400hp. I'll be looking to hit it with a 200 shot and possibly push it up to a 250 or 300 as my setup develops.
The kicker is.... I want to do this with stock pistons...
I know...
Has anyone gone to a steel top ring on the stock pistons with any luck? I've got the engine on the stand, now would be the time to do it...
a piston upgrade will come in the future, its inevitable. but it will also mean more ci and I'm not wanting to do this yet. I really want to push the stock shortblock and see what it can handle. It will take patience, meticulous tuning, and careful monitoring of the entire system to make it happen and live thru it.
I've sprayed plenty of these engines on stock rotating assemblies up to a single stage 250 hit with good luck... only one melt down from an injector issue.. That being said I'm not shooting from the hip here. I'd just like to know if there's any upgrades I can do (even a different gap on the stock rings) that would help it live longer.

IS the L92 ring package any diff then the ls3? If not, you'll be fine 
with a proper tune, Ask me how I know this.
The ring land will go before the ring will cause you problems.

I'm guessing for production cost sake its the same but I dont know this for a fact. I do have the flat top pistons with valve reliefs stock so maybe???
and yes, I'd like to know how you know

I was looking for a new set of rings to freshen up a shortblock and all I could find was Hastings 2M5292. I'd like to find a ring set with a napier 2nd. Total Seal has some new offerings but they're only for aftermarket pistons as they have a 3mm oil ring.
Throw the bitch in there. I've been thru all what you guys are talking about. I looked for an aftermarket piston and there are only like two the last time I checked with a 4.065 bore. I then said **** it, I will leave the stock pistons in there and just freshen it up. I looked for rings and Hastings was the only company with a set for the 4.065 bore.
I then said **** it again and bought a 416 rotating assembly from TSP. No more worries.
As far as the nitrous, with the right tune it will take more than you think. Carter01 in the nitrous section is on a 300 hit on the stock longblock with only a cam and he just ran 9.80's on a soft 1.4 60ft. He usually cuts a 1.34 60ft. So 9.60's is in his future. Full weight too.
