the purple one is my 55 and the blue is my 57. i did the 55 pretty much stock a while back. when i got the 57 i knew how to do things and i changed things up. i added extra lines. such as nitrous, fuel, oil.... i took a oil pump from a stock car and used it as a fuel pump, which turned out really cool. i used a shotgun style scoop from a muscle machine car, i cut and glued a top fuel wing to the back, which i got from a fellow model car builder on here. i hope to get better pictures but the flash messed them up. this was the only one worth puttin up. thats what i get for having a cheap camera
