If you're into modding yourself it's easy to just create your own race and adding the starting techs that you want to it.
You just need to mod the race config file. I don't know of any specific mods that have a stronger starting race. It tends to make it unfair.
This is a race that I made just as a tests once. The Tech's are at the end, as you can see I added quite a few. It was way too easy to win with this many techs but it will give you an idea of what to do. You get the names of the techs from the TechTree file
