When you're planning on making 400whp and above there is a lot of planning and parts that are required to support the power that we don't always think of. In this video I share what parts I had to get in order to be able to support 400whp in my Subaru Impreza GC8. Of course, if your starting point is a different model or platform then this list will be different but this video can give you an idea of what you need to be aiming for.
