We design this kit for the guys who are looking for more fuel but not necessarily needing a dual pump set up.
Our Walbro 485 kit will allow you to fit a Walbro 485 pump inside the tank and still retain the Oem Venturi system, OEM filter, OEM lines.
We also includes components to switch out the OEM fuel pressure regulator to a 1:1 rising rate regulator without sacrificing the oem siphon. Scion FR-S Subaru BRZ
We received more Arias/FBM Custom pistons in stock with upgraded wrist pins. You can see in the photo of the standard duty pin versus our upgraded pin.
Our pistons are designed to handle 30+ psi of boost with larger rings, skirts as well as other advantages over most off the shelf piston.
