HAHAHA. Thread was definitely worth multiple laughs. Epic find!
Wikipedia said:Starting in 1994, Toyota solved this problem by offering a Roots-type supercharger with air-to-air intercooler, providing 6psi of boost (these models were called the "S/C"), bringing the engine power up to a competitive 160 hp (120 kW). Initially, the S/C engine was only available as an option on the LE in 1994 and all models in 1995. For 1996, the normally aspirated engine was discontinued, and the S/C became the standard engine on all trim levels.
FSWerks has done a few turbo kits on the transits.
