i would go with one of the go engines i here they are great for the money.and for another car i would reccomend the Cen Matrix it is one of the most underrated buggys out their today its tough and very fast on the track i have had mine for about 2 months or so and i love the car and i have owned the higher end cars but the car is awsome .
