Then you use the search function to search specific forums and even specific threads based on what you learned in the link above to find out about the specifc mods you want to do.
Finally, if you have questions that weren't already answered, post a question in the correct forum.
That said, anything regarding modding these cars is most likely covered and espeically what you need to get to your power level goal.
Oh yeah, posting some pics of your new toy would be cool to.
