The limitation is what fuel you have access to. You can hit 300 whp on the Vortech kit with E85 or a similar higher octane fuel. You can also barely hit it on the Innovate kit. If you want to do it on a 93 octane fuel, then the Kraftwerks C38 kit would probably be your best bet, but I haven't seen anyone with that independantly hit 300whp yet. I wouldn't worry about the spark plugs or changing them. Almost everyone is running the OEM gapped spark plugs with their forced induction kit. If you are worried, you can pull them out and gap them a little tighter.
