i would say JR supercharger cause thats what i got im only on 5 pounds and it pulls pretty damn hard for a D. we also have the same engine. i raced a B20 and won so that should give uan idea of how it runs on 5 pounds
Yeah but their kind of hard to get your hands on since they discontinued all D series superchargers , but what else do you haveunder your hood to go with that ? and after market engine mods ?
