The high-pitched scream of that engine made her Mitsubishi Mirage a nine-second car all day long. The 4G63 head was like icing on the cake when it came to the rebuild that created the fastest street racer Detroit had seen in a decade, and this one belonged to a girl. When she entered the racing scene with her sea-foam-green Mirage with the jet black stripes, even the boys who raced every weekend got a little nervous. The reliable sellers on eBay always had her back when it came to replacing that 4G63 cylinder head with a new brushed aluminum head. They even had the right 4G63 head gasket to complete the changeover without missing a beat. It really is not that rare these days for a girl to love a fast car just as much as the boys do, but this girl has something special when it comes to winning races. She takes the checkered flag on the quarter mile without even messing up her hair. That 4G63 head definitely gets a workout when that Mirage hits the road.
