I know Mike sells the best pinions. Here are a few links for good spur gears:

Sorry for the long list, I actually was looking for the same thing a made it a while back. I would personally go with the biggest pinion I could fit. I run a 1521/1Y in my truggy and it is a new experience compared to any Feigao type XL motor. The only motors that will match the 1521 and 1527 are the Lehners 22xx. I'm actually waiting to put my 1527/1.5Y in a new chassis after I get it done or Mike does it for me.

IMPORTANT: Get the best damn battery you can find and a 2P will be the way to go. Use the biggest bullet connector and 10GA wires.
