I would recommend the metal servo saver(if not equipped) the metal servo horn, upgrade the servos, lightened outdrives(personel choice), extra clutch bearings, extra tie rod ends, the covered hex nuts(the stock ones allow dirt and moisture to get into the axle shafts, making the grub screw rust and get stuck), do the shock mod( it's on this sight, recommend using tire foam over the doubled up o rings), extra shock blatters, the turbo conversion if sticking with the 350, extra plugs, Dymanite Max Life clutch shoes, tires/ rims/ inserts of choice( recommend AKA), a good caliper for reading measurmeants, and then just pratice and have fun.
