Looking to convert a xb9, looking for the conversion kit and a esc if possible

There is no conversion kit as such
I did mine with a Losi 8igjt battery tray $40 and an integy xray 808 conversion kit (just used the motor mount) $60
Got them both from OZrc
Chop the Nitro radio tray in half to keep your servo mount

Ok thanks for that bro
