Converting Revo to Electric

Well there is a lot of threads in here that deal with converting Revos ,but I couldn't find exactly what I needed. So I made my own thread.

I'm new to electric R/C (I do know electric know how just not in R/C).

I've been deciding to convert either my LST or Revo to Brushless and Lipo power and I decided to convert my Revo.

I plan to race my revo and want to reach at least 40-45 mph top speed with my truck. I also want to have nice runtimes that I can race with. 25+ minutes.I'm guessing for the ESC MMM when it comes out.
What I'm wondering is what motor and battery will satisfy my needs ,but not break the bank.

Oh and I also am planing to use the Tekno R/C conversion.
