If you want a fast 19t motor get a corally black edition there slightly more exspensive but the are a very fast 19t motor. And have amazing acceleration. As for speedo. See if you can pick up a cheap second hand nosram dominator evolution off ebay. Limit is either 5turns or 7 turns and as everyone is going brushless there will be alot of people selling them.
As for cells speak to neil at
www.stormforceracing.co.uk Sanyo 2400 are fine for 2wd with a 19t motor or if you want extra punch and duration get. His IB 4200.
