I have a handful of engine-building and engine-measuring videos spread throughout the channel for Subarus (WRX/STI etc). However, all of that info is scattered. So I figured it would be best to try and compile everything into a singular video for those who want to DIY and Build their own engine but do not know where to start. So I hope this video helps those who need it!
