Papadakis Racing Stroked B58 Inline-Six

Andre Simon from High Performance Academy interviewed Stephen Papadakis from Papadakis Racing about their B58 engine development for Fredric Aasbø’s 2020 GR Supra. Depending on the track, the car runs a 3.0 L B58 inline-six or a stroked 3.2 L B58 inline-six capable of 1200+ horsepower on E85 fuel. Stephen explains the engine stills uses the factory aluminum block with a stock bore and factory oil pan. Aftermarket parts include a Brian Crower 100 mm stroker crank, Brian Crower MOAR I-beam rods, JE forged pistons, and King/ACL bearings. On top sits a B58B30O1 six-port head with Supertech valvetrain, and six ID 2000 cc injectors. A BorgWarner 9280 turbocharger provides the boost. Listen to Stephen explain how his company developed a 1200+ hp B58.
