RE: servo torqe*
If you are upgrading from stock rtr servos, then a Hitec 645mg or the Futaba 3305 is a good choice for the price (around $30). If you can spend $50 or so, then the Hobbico CS-160 is a good servo.
For a B4, I would be more concerned about speed then torque. Just get what you can afford, but the more you spend the more you get. Once you get high end servo's ($100) they will spoil you and you will never want anything else. I love my Hitec 5955 and JR 9000s.

Iuse a Savox SC1257TG in my B4 which was originally intended as a helicopter rudder servo but is listed as suitable for car use. I completes a full swing at 6V in .07 seconds and can push 138oz-in of torque. That's plenty of power and speed for a 2wd buggy. You really only need about 75 ounces of torque but, more doesn't hurt. Acutally, .07 seconds is almost too fast; speeds less than .2 and down to .12 are pretty quick and are noticeably faster than the stock servo.
The Savox SC1251 and 1252 are low profile so they weigh less but still push over 120oz-in of torque and have a .09 second transit time.
As you can see everyone has their favorite brands. I really like Futaba equipment but, these Savox units have been working for me and they have a lot of different choices available. The servos the other guys listed are good, have plenty of power and aren't too expensive.

In my B4.2 kit I put a Radiopost (local company) Speed servo which does a .05s/60 swing with 138Oz*In torque @ 6.0V. In my E-Revo I use their Torque servo which does a .09s/60 swing with 419Oz*In torque @ 7.4V. I like fast servos though. They run $120 a piece but are very good for the money.
Like everyone is saying though B4's and other small buggies don't need much torque focus on speeds below .15s/60 if you can find them at your price point.

100 oz-in or more, as fast as you can afford. Hitec 625 is a cheap good quality option.

Go to google and type (carefully, you must spell the unit names correctly)...
"convert 100 ounce inches to kilogram centimeters" - without the inverted commas.
Google search has not failed to convert anything I've asked it to do over the years, provided you phrase and spell the units correctly it gives you an instant result right below the search box.
