Only 150 of these exceptional SE30 models were built. 15 of which were converted to "Jota" specification although 28 Jota kits were produced. The "Jota" was a factory modification kit designed to convert race-oriented SE30 into an actual circuit racer, albeit at the cost of a street-legal operation. A revised engine lid with two ducts protruding above the roofline forced air into the intake system; a similar lid design would later be used on the Diablo SV model. With even more tuning of the Diablo's venerable V12 engine, the Jota kit produced nearly 603 PS (595 bhp) and 639 Nm of torque. An open exhaust system produced deafening engine roar, one of the main contributing factors to the Jota's track-only status, although some owners converted back to standard exhaust in order for enjoy their "super Diablo" on the road.
