What you have is a completely different car not upgradable to become a F14 EVO.
If you're not racing it against anyone, I would just enjoy it as is. But if you if you want a car that is faster than it should be, get a F14 EVO and put a brushless/lipo combo in it. I only have a 5.4 Tekin mini rage and it is way faster than it needs to be for the size track I run it on.
