I'm posting this about a friends car.Its a 91 integra 1.8 with i/h/e,act 2600 and a claimed 50 shot pill.Its a nos dry kit and it doesnt seem like its hitting hard enough.By that i mean spray 2nd gear and they wont even break loose .Weve moved the nozzle,it has normal grey plugs,and its definetely spraying into the engine.My guess is either i'm used to faster cars or a 50 shot really doesnt make much of a effect on that kind of car.
