Hello everyone. I have a forged LS2 403ci in my 2002 Camaro Z28. I have ARP 2000 head bolts and ARP 2000 main studs and rod bolts in the bottom end. Scat forged H-beam rods, crank and Autotech flat top forged pistons. I am using a ported fast 90mm with worked up 215cnc Trick Flow heads. (we opened the head up to match the bore of the motor and dropped in bigger intake valves) We are figuring the motor is making between 600-650 flywheel hp. I just ordered my Nitrous kit for the motor and was wondering what the limit of the LS2 block was. I am wanting to hit the motor with a 200 shot. Another concern I have is I am about 12.3-1 compression on this motor so I am a little concerned about lifting a head. Any thoughts on this?
Thanks

Wet or dry? If wet, I recommend a standalone. Then you can hit it with a 200 shot without a problem with the right tune: Colder non-projected plugs, timing retard, etc.

I'm going to hit it with a wet kit with a stand alone fuel cell. The car will be tuned for the 200 shot.. I am going to go through all the right directions to get this done. I am not really worried about the bottom end as much. The thing I am worried about the most is lifting the heads because of spraying it with a 200 shot and running 12.3-1 compression.. Also what is the HP limit of a LS2 block? Has anyone ever went higher than 850-900hp to the flywheel on these aluminum motors? Will it hold?

You will be fine. There are guys shooting way more with just stock hardware on their motors. Just got to get to the track and tune it. Trying to tune it on the dyno will spell disaster at the track.
