Do you guys think I will be ok on a heads and cam car putting a 75 shot of nitrous on it. I got new plugs and was going to buy a inline pump but the guy I bought it from said i didnt need it. The kit is a TNT wet kit by the way.

 

What are you putting down now, any idea? Even for just 75 you're probably on the borderline. Make sure to keep an eye on your AFR until you're sure everything looks okay. If it were me, I'd go ahead and install the pump since you have it. Once you try 75, you'll want more anyway.
