As i was reading up on the 1jzgte i read that as well as being a twin turbo it also came with a single turbo. Now for all the people that go single or are looking to would this be a good place to start if not wanting major power instead of modding the twin turbo just to start with the single turbo and upgrade that???

 

The JZZ30 was powered by the 2.5 litre 1JZ-GTE turbocharged engine. Initially featuring two identical small turbos running together (unlike the sequential twin turbo systems of the Supra and Mazda RX-7, for example), it officially produced 206 kW (280 PS; 276 hp) and 363 N·m (268 lb·ft) of torque at 4800 rpm. This was in keeping with the Japanese Manufacturers' advertised power limit agreement, however real-world power outputs were somewhat higher. In August 1996 the engine received Toyota's variable valve timing system (VVTi) and in conjunction with a single, more efficient turbocharger, produced much better high and mid-range torque (in fact, 378 N·m (279 lb·ft) at just 2400 rpm - see The Toyota JZ Engine Guide below) while still producing the "official" 206 kW (280 PS; 276 hp) of power and better fuel economy.
