What does this all mean?
If you have a Subaru equipped with an EJ205/EJ255/EJ257 and want more pep than the factory shmol boi can make, this unit is a solid upgrade. It’s a direct bolt on replacement, meaning it will bolt in/out just like the OE shmol boi does. But, keep in mind you’ll need to upgrade your fuel system accordingly so you don’t melt stuff. Oh, and you'll want a built bottom end to handle the amount of torque this medium boi can make. If you don’t know what you need to make this turbocharger work, shoot us a message on the website or email
