Geo Storm/Impulse Modifications

This is a list of most of the upgrades I have done sofar. The latest on the Engine swap and other timelines can be found on my Blog.
Since I don't like to waste anything, I will be dropping the Storm engine into the RS and making sure it runs, clean up some of the rust, then selling it. I plan on removing the AWD and keeping it and probably installing it into the Storm.
