Rc Cars Engines

im building RC cars and can not decide which of these engines to choose?

I'm building my own RC truggy that, I can not base, and they decided between the HPI Nitro Star K5.9 or K4.6 HPI Nitro Star HO. there are both the same price and the show dosent 5.9 specification then wondering what is faster for truggy

Engine 4.6 is better for truggies. It is the engine used in the new truggy HPI Trophy.
