always go with a wet kit, If you don't your gonna be relying on your stock injectors to supply more fuel by way of increased line pressure. I don't know about you but I like to know i'm getting enough fuel when i'm on the bottle. Your also gonna need a bottle warmer and a guage. Never spray under 3000 rpms and anything less then full throttle. It would be a good idea to run 93 octane fuel too. I wouldn't go over a 100 shot on the stock s2000 motor, 75 should be plenty for what your wanting to do....pm me if you have any questions
