Toyota K engine
Template:About Template:Use British English Template:Use dmy dates Template:Refimprove Template:Infobox automobile engine
The Toyota K series is an inline-four engine that was produced from 1966 through 2007. It is a two-valve pushrod engine design. It was originally built from the Toyota Kamigo plant in Toyota City factory in Japan.
All K series are non-crossflow engines – the inlet and exhaust manifolds are on the same side. They have cast iron blocks and aluminium alloy heads, with a crankshaft supported by five main bearings. K series motors have both hydraulic tappet or hydraulic valve lifters, solid lifters and 1.5 ratio rockers with an adjustment thread for tappet clearance. 7K engines were released with only the hydraulic valve lifters from factory, whereas 4K and 5K engines were made with both hydraulic and solid lifters (depending on year and which model vehicle.)
KEdit
The 8-valve OHV Template:Convert K was produced from 1966 through 1969. A similar K-B was produced from 1968 through 1969, the -B designates twin carburettors. Thus equipped, the engine produces Template:Convert at 6600 rpm.<ref name=Toy75th>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> The Publica SL received this more powerful version.
Applications:
- Toyota Corolla (KE1x)
- Toyota Publica (KP3x)
2KEdit
The eight-valve OHV Template:Convert 2K was produced from 1969 through 1988. The cylinder bore and stroke was Template:Convert.
Output in 1978 was Template:Convert at 5800 rpm, and Template:Convert at 3800 rpm.<ref>Template:Cite journal</ref> In 1983, New Zealand received a version with Template:Convert at 5800 rpm, while Europe received a version with Template:Convert at 5600 rpm, both with a maximum torque of Template:Convert at 4000 rpm.
Applications:
- Toyota Publica/1000 (KP30/KP36)
- Toyota Starlet
3KEdit
The eight-valve overhead valve Template:Convert 3K was produced from 1969 through 1977. Cylinder bore and stroke was Template:Convert.
The 1969 through 1975 3K-B was a twin-carburetor version. The California-spec 3K-C (1977–1979) and 3K-H were other available versions.

3K-REdit
The 3K-R engine, also known as the 137E, was a special version of the standard 3K fitted to the Toyota Starlet (KP40) for use in touring car racing in Japan. The engine was developed by TOM’S in 1974 and was one of their first major developments as a tuner for Toyota. <ref>Template:Cite news</ref> The 3K-R has a 16 valve dual overhead camshaft cylinder head with a compression of 13:1 and was fuelled by a Nippon Denso built mechanical fuel injection system. The engine was also bored out to 1.3 L (1293 cc) and had a dry sump oil system. The engine produced Template:Cvt at 9000 rpm.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

The Template:Convert 5K was produced from 1983 through 1996. Typical output is Template:Convert at 5600 rpm. Bore and stroke is Template:Convert. It was available with either 4- or 5-speed manual transmissions. Like the smaller 4K model, it uses hydraulic lifters as well as solid lifters for the pushrod.Template:Clarify

Template:Anchor 7KEdit
The Template:Convert 7K was first introduced in 1983. Cylinder bore and stroke was Template:Convert. Output was Template:Convert at 4600 rpm and Template:Convert at 2800 rpm while the EFI version which can be found in Toyota Kijang KF80 produces Template:Convert at 4600 rpm and Template:Convert at 3200 rpm. The Engine was available with a 5 speed manual & 4 speed automatic transmission. Available in both fuel injected and carburetted configurations, the 7K produces much more power and torque compared to the other K engines however it is a lot less 'rev happy' due to having such a long stroke.
7K-E is available in KR42 Townace SBV vans (1997–2007) using a large G52 5 speed gearbox (same bellhousing to box pattern as W55), or automatic.
