The 2-valve [[SOHC]] {{convert|1972|cc|L|1|abbr=on|order=flip}} '''21R''' was produced from 1978 through 1987. Cylinder bore and stroke are {{convert|84x89|mm|in|2|abbr=on}}.

Output for export markets, largely unconstrained by emissions, was {{cvt|100|PS|kW PS hp|0|order=out}} DIN at 5,000&nbsp;rpm and {{convert|154|Nm|lbft|0|abbr=on}} at 4,000&nbsp;rpm. Air injection and federally compliant emissions equipment for the '''21R-C''' (1982–1985) dropped power down to {{cvt|90|hp|kW PS hp|0|order=out}} SAE net at 5,000&nbsp;rpm. The air-injected Japanese version, the '''21R-U''', produces {{cvt|105|PS|kW PS hp|0|order=out}} JIS at 5,200&nbsp;rpm and {{convert|162|Nm|lbft|0|abbr=on}} at 3,600&nbsp;rpm but dropped to {{cvt|100|PS|kW PS hp|0|order=out}} at 5,400&nbsp;rpm and {{convert|154|Nm|lbft|0|abbr=on}} at 4,000&nbsp;rpm in 1986.
