All depends on how much you want to spray at it......

 

i was thinking a 100 wet, maybe 150.what do you think?

 

You can spray up to a 150 pretty safely on your stock internals. One problem you could possibly run into is your fuel pump maxing out.
To be safe, I think you should consider a Walbro intank fuel pump of 255lph or more. This will insure that your don't have a fuel starvation problem. Which could create a lean condition.

I have always been a firm believer in upgrading your fuel system for any nitrous application above 125HP, wet or dry. It's logical to do so, if you plan on doing alot of modifications anyway. Its a cheap upgrade.

 

Run a 100 shot if you're going to spray it often. I ran 10-15 bottles through with a 150 shot with no problems really. I feel that a 100 shot is "safe" and a 150 shot you're teetering on the brink of disaster. The LS1 can handle roughly 20hp per cylinder with stock internals.
