context_page_description: The Toyota R family was a series of inline-four gasoline automobile engines. Designed for longitudinal placement in such vehicles as the Celica and Hilux and in production from 1953 through 1997, usage faded out as many of Toyota's mainstream models moved to front-wheel drive. Overhead cam versions featured a chain-driven camshaft.
context_section_description: The 1.9 L (1,897 cc) 3R family was produced from 1959 through 1968.
  When introduced it had a 7.7:1 compression ratio. In 1960 the 3R was uprated to 8:1 and the 3R-B version was offered from 1960 through 1968 with the old 7.7:1 compression ratio. The 3R-C was introduced to comply with Californian emissions laws. The 3R-LPG variant was made for the last five years.
