okay, i just finished pulling my engine today. in the next week or two i'm going to be sending the heads off to be ported and polished and get a custom cam through AI. its going to be a good setup i think. double roller, Lt's, 58mm tb, injectors, etc. the point is that i would like to set this engine up for future n20 use. ive contemplated the turbo/supercharger route and have decided against it completely. however, i havent heard a lot of bad comments about nitrous use and i imagine if i pre-plan for it and set my engine up a little better that i should have little or no problems. ive tried doing a search on this stuff, but without specific phrases, it wasnt much help. and theres not too many pages on the current board to review. anyways, i'm thinking that i could leave my stock crank intact considering i dont have plans on making more than ~550hp (ive read that the stock crank is fairly decent up to ~700hp...?) but i am planning on replacing the piston heads to some forged ones. any suggestions on which heads to add to this setup? and also, any recommendations on which kit would be a decent one for a 100-150 shot? any and all info is appreciated. thanks.

[edit: just realized i put "NO2" in the title instead of "N20." ...idiot moment ]

 

If you're going to go forged, a good set of SRP's, JE's, or Ross pistons will do you great. They say typically off the shelf forged pistons will handle around a 300 shot. If you plan on squeezin more than that, then lean towards some custom nitrous pistons....

For a good 100-150 shot on an LT-1, I'd recommend an NX wet kit (PN 20920-10). I think most of the people on this site would agree with this recommendation. If you plan on sprayin over 100 shot, you're going to want to upgrade your fuel pump as well.
