Dustin’s Scion FR-S received a BEAMS 3SGE engine swap just in time for TX2K15. Days before departure the turbo kit was coming together. Hours before departure it was loaded on the dyno for a full tune. A few days and 2000 miles later it was returning home from it’s successful maiden voyage from Kentucky to Houston TX.
Coming from a Toyota MR2, Dustin was very familiar with the 3S engine series. The BEAMS variant was an obvious choice for his FR-S engine swap, combining the solid cast iron inline 4 cylinder block with an improved cylinder head featuring dual cam control. Once the engine was in place planning began for the rest of the setup. A custom turbo manifold feeds a Precision Turbo 5866 billet turbo, which feeds a custom RacerX/Dynosty intake manifold. The FR-S was originally equipped with Drive By Wire, and that feature was retained and improved upon with a larger throttle body and a Haltech Elite 2500 standalone engine management system. The Haltech Elite 2500 has standalone control of the engine, and flawlessly runs the dual cam control, drive by wire, knock control and more.
The BEAMS 3SGE swapped Scion FR-S is just getting started at 330WHP on low boost and 93 octane pump gas – which would be near the limit on the stock boxer FA20 engine found in the FR-S. Check out the dyno chart and video below, and stay tuned for more updates as we increase boost, rev limiter, and setup flex fuel for E85 tuning.
