I might be getting a NOS kit, how well can our ls1's hold NOS if im running about 125 shot, my engine going to blow up?

Stock engine with just msd plugs wires, headers, ypipe, ls1 intake slp lid slp maf

 

you'd be okay with the stock set up running a dry 125 shot. some guys think you shouldn't go over 100 with a dry shot. up to you.

I personally am going with a wet shot from NOS, and shooting 150

 

Does it clog up your engine or anything, is it worth it you think

 

You should be fine, just swap to a TR-6 plug or something comprable. You may also want to ditch that SLP MAF for a stocker since that could present a few tuning issues. My stock long block has a seen a few 200rwhp shots but I generally run a 150rwhp shot. It's held togethor fine for a few years now and there are tons of other people running similar set ups. The key to keeping them togethor is saftey measures and a good tune.

 

you bet its worth it And no..a 100 or 125 shot will not give you any problems. Just keep reading this forum and learning. If you think of specific questions try the search feature and look up existing topics. If they are not answered make a post and ask away. Good luck!
