The GT500 pump is a great option if you're looking to support a small amount of boost. However, if you plan on bigger plans down the road, I would suggest a twin in tank pump kit. This way if you decide to upgrade, you won't have to go through the hassle of dropping the gas tank again and buying another pump.
For fuel delivery, I always try to upgrade once and save some cash and hassle down the road. Although, if you plans don't go farther than this, then the GT500 pump will be perfect.
Good luck with your build! I just wanted give you a few tips before pulling the trigger.
