Supra / SC300 / Soarer / GS300 Products


This page serves as an overview for my most popular Toyota/Lexus items
I've been building and servicing Toyota Supra MKIVs for the last 18+ years. From simple TRD gauge cluster swaps to custom build prototype-projects like PnP 850HP OEM Twin Turbos to full restorations and builds - I've done it all. Every project is unique and requires personal advice and consultation, so there is no "shop" on this page. Every item is build by hand and thorougly tested before delivery.
To place an order please CONTACT ME via E-Mail or Facebook 

IMPORTANT UPDATE 6/17/2021: I'm currently have a backlog of about 7-10days due to pending orders!
