Flows Automotive’s 2005 Lexus IS200 originally came with a naturally aspirated 2.0 L 1G-FE inline-six. They eventually grew tired of that and swapped to a turbocharged Saab B204 inline-four on custom mounts. The engine features stock internals, custom baffled oil sump, Holet HY35 turbocharger, custom exhaust manifold, and Siemens 660 cc injectors. Flows Automotive retained the factory Toyota J160 six-speed manual transmission, driveshaft, and rear end thanks to a custom adapter they designed.
