You can not have different empires start with different levels of technology. However, you could mod in a new racial tech trait that gives copies of the most advanced items you wish to start with. I will call it Uber racial trait. Then, add a tech area, such as Uber Tech, which all of those components, facilities, etc. require. They only require Uber Tech. Set the Start Level of Uber Tech to 1, so you will start with level 1 in it. Thus, you will start with the equivalent to high level technology if you select this trait.
