I have had a few different cars and quite a few different engines. I sold most of the race level cars but still run my RS4 Racer here and there.
It has a Mugen MT-12 in it and man does it fly around the track. The RS4 is not on the same level as the race breed cars but its very cheap and light. The MT-12 hauls this thing around the like a rocket....lol

I think they still go for around $150 or so online, maybe even a bit cheaper if you look in the right places.
You would need to be sure and get the standard shaft if you decided to try one.

This is in my opinion one of the best most powerful engines out there.

The O.S stuff as mentioned in previous post in my opinion is good stuff too, I also hear the Fantom engines are really good.

I think you would be happy with any of these.
