a cast iron block with aluminum cylinder head. Output was at 5,600 rpm and at 4,400 rpm. In 1998 VVT-i was added, which bumped output to at 6,200 rpm and at 4,400 rpm for the Altezza/IS 200. Production of this engine family ceased in 2008 after the discontinuation of the Crown Sedan mild hybrid. Applications: Toyota Altezza/Lexus IS 200 Toyota Crown Aug 2001–Aug 2008 Toyota Crown Sedan GBS12, GXS12 Toyota Chaser/Mark II/Cresta Toyota Mark II Blit Toyota Verossa Toyota Supra Toyota Soarer 1G-GEU The 24-valve DOHC 1G-GEU was intended for high performance and featured a pent-roof combustion chamber. Introduced in August 1982 and produced through 1986, mostly for the Japanese market, output was at 6,200 rpm and at 5,600 rpm. This was Toyota's first multi-valve twincam engine to make it to the market, and won the "JSME Medal for New Technology" (Japan Society of Mechanical Engineers) in 1982. To minimize the downsides of a multi-valve setup, the 1G-GEU was also equipped with T-VIS (Toyota Variable Induction System), increasing low to mid-engine speed torque. Like all following twin cam Toyotas, it used a timing belt rather than chain, for less noise and lower maintenance requirements. In August 1983, the fuel injection system was changed to EFI-D, which measures the pressure in the intake manifold to determine the proper air-fuel mixture. Applications: Aug 1982–1985 Celica XX GA61 Aug 1982–1992 Toyota Chaser/Mark II/Cresta Aug 1983–1995 Toyota Crown Feb 1983–1991 Toyota Soarer 1G-GE The 1G-GE replaced the 1G-GEU in 1988. It was detuned from to and served the same cars as 1G-GEU did. Torque was at 5600 rpm. It was produced for the Supra GA70 until 1993. 1G-GTE The 24-valve DOHC 1G-GTE added two CT-12 turbochargers to the versatile motor. There were 3 generations of this engine both air-to-air and air-to-water intercoolers were used, pushing output from at 6200 rpm and at 3800 rpm using the air-to-air over the air-to-water. This was the most powerful engine of the whole G family. In May 1991 it was replaced with the 280 PS 1JZ-GTE on most Toyota cars. Applications: 1986–1992 Supra MK3 (GA70; JDM only) 1986–1992 Mark II/Chaser/Cresta (GX71, GX81) 1986–1991 Soarer (GZ20) 1G-GP/GPE The 1G-GP and 1G-GPE was an LPG version of the 1G-GE engine. Output is at 5600 rpm and torque is at 2400 rpm. Applications: Toyota Crown Sedan (GS130, GS151) Toyota Crown Comfort/Sedan (GXS10) 1G-GZE The 1G-GZE was a supercharged version produced from
