As for your car, that looks a good bit of kit. I'm in the UK and I'm not familiar with that brand, but I've had a look on the net and it looks a really strong truck. The infinity engines are good engines as well so reliability won't be a problem either.
Your best bet is to take the car along to your local hobby shop. They'll set the engine up for you depending on if you've 'run in' the engine or not, as that will require a different set up from the full on set up.
