R92A/B

Racing engines based from bored up FE engine, the displacement was increased from 958 cc to 1261 cc with new 78.0 mm bore size from FA engine. This new engine was known as R92A and used for powering the 1965-1966 Daihatsu P3 and 1967 Daihatsu P5 race cars. The cylinder head was also modified from 8-valve OHV to 16-valve DOHC, an extremely rare configuration at that time. At first the power output was originally 110 PS (81 kW) which was then increased to 130 PS (96 kW) at 8000 rpm.[10]

In 1968, the engine displacement was increased again to 1298 cc with new bore and strokes of 78.5 mm x 67.1 mm and also renamed to R92B. Equipped with new two Mikuni-Solex 50PHH carburettors, the power also increased to 140 PS (103 kW) at 8000rpm with 127 N.m at 7000 rpm of torque.[11]

H
Main article: Daihatsu H-series engine

The Daihatsu H-series engine is a series of SOHC 16-valve inline-four water-cooled petrol engine, ranging from 1.3 L to 1.6 L.

J
Based from Japanese Wikipedia article

The Daihatsu J-series engine is a series of the inline-four engines specially for Daihatsu's kei cars that was produced from 1994 to 2012. This was the first and last inline-four engine for Daihatsu's kei cars, debuted on L502 Daihatsu Mira that was launched in September 1994.

The specification is water-cooled inline-four cylinder DOHC 16-valve EFI, the bore and stroke size is 61.0 mm x 56.4 mm, which made 659 cc of displacement. The camshaft was driven by a timing chain, which is very rare for a kei car at that time.

It features smooth engine rotation, low noise, less vibration and quite powerful power in its class (turbo version). But since the stroke is short and volume per cylinder is small (164.75 cc) compared to the inline-three engine (±220 cc, which is common for kei cars), the torque characteristics and fuel consumption in the lower rpm is not that great compared to inline-three engine. For this reason, it can be said that the engine is more specialized for sport driving rather than "stop and go city driving".

Based on the turbocharged JB-JL engine, the JC-DET engine that powered the M112S Daihatsu Storia X4 had its displacement increased to 713 cc by lengthening the stroke to 61.0 mm, making it a square engine (61.0 mm x 61.0 mm).

On 31 August 2012, as the production of the first Daihatsu Copen ended, the production of the J-series engine ended as well. Daihatsu has announced that it will integrate the engine for kei cars into inline-three in the future (EF engine).

The third digit of the car number model (xx2), is a sign that the car is powered with J-series engine (except for Daihatsu Copen), for example: L502 Daihatsu Mira or L902 Daihatsu Move.
