wich ESC/motor

Why do you need such a high kv motor for? General rule of thumb is you want the brushless motor to spin about the same speed as the nitro motor that came out of it. I don't know the setup on the car you mentioned but I'm sure it's similar to most 1/8 vehicles. Your going to want to run at least 4s if not higher for efficiency. At 4s something in the 2000-2200kv range is generally used, 5s 1600-2000kv, 6s 1300-1800kv. A 4500-6000kv motor in a 1/8 would need to be geared with about a 5-6 tooth pinion to be useable without pulling enormous amps on start up
