What does it take (parts wise) to go through with this, I <3 downtime, so I will probably buy an extra wrx block to do this, I know I need to buy sleeves and the whole nine, but I wanna know exactly what I need to do this.

I was going to buy a 2.5 from bobnissan, but due to problems with the transaction I am going to just do a 2.0 -> 2.2
