Marvin, im not sure if you have purchased a car yet but have you thought of getting an FG especially as now they have electric conversion available. You could also use the SKY RC 1/5 scale setups to save some cash here are some links.
You could pick anyone of these models from very basic and RTR to all out comp models

I use all castle gear in my 1/5 conversions as well as NEU motors but you could also give SKYRC a go.
