Hello all! I'm SPOOLISH. It's awesome to be among the beginning of a huge car scene that's in its infancy!! Anyways, I've come across a lot of information on the RS that excites me. I have found a mustang EcoBoost online that makes 500hp on ALL STOCK INTERNALS. The car made the power with a 5858 turbo and some other supporting mods. This is really exciting because the focus rs has a better engine and a bigger turbo stock, well, not bigger than the 5858 lol. Now, we don't know what the stock turbo can do just yet but I think its safe to say the engine is very capable of 500hp safely and reliably.
