I have a 93 trep with all the goodies I can think off other than NOS. I have heard so many stories about how harmless it is, and how harmfull it is. I don't care how it affects cars in general, I care about how it affects a 3.3L. Anyone know (hopefully from experience) if having a 75 shot NOS will tear up the engine any? I hope someone out there has some insite on this. Thanks.
