How much extra does one need to spend to make this go the advertised 50 mph?

Yes it will do 50+ and if you get the spektrum DX5C TRANSMITTER REMOTE IT WILL GO EVEN FASTER. ALONG WITH SOME GEAR AND SHAFT UPRGRADES MINE DOES 68-71MPH

Can it handle 100c Lipo ?

Using a battery that sustains the current demand of the motor is what is required, regardless of the C rating. Typically 5000mAh and 25C for vehicles this size are more than adequate. The difference between two 5000mAh batteries, one rated 25C and the other 100C would likely be unnoticeable as either would have the ability to deliver sufficient current. Higher quality cells from a reputable manufacturer would be a greater benefit than running the highest C rating that you can find.

Will both the 21t and 26t pinion gears for all the arrma 3s blx vehicles (models) fit?

Yes. Just keep an eye on temps. I think Arrma used a 20t to optimize speed and reliability.

What batteries and charger so I need for this? Also will I need anything else?

3s smart lipo + charger is advised. They can be pricy so I use a 2s smart battery and charger instead, and it still goes over 40 mph just fine. Also, the car has an ic5 battery connecter. Be sure to check whether or not the battery you buy has an ic5 or not. If not, you can get an adapter for a few dollars. After you have a battery and charger, you will be good to go.
