I'm running a Kyosho Inferno Sport with the GS .21 motor that came with the car, but I don't feel like it is enough power for racing, which I would like to get into.

Can I please get a few suggestions for a new motor and where I can get them? I have heard that the OS RZ is a good options and possibly and RB motor, but I don't know where to go on the web to buy them.

Any suggestions on pipes would also be appreciated!!

Thank you in advance for your help!!
