Editing Toyota R engine (section)

===7R===
The {{convert|1591|cc|L|1|abbr=on|order=flip}} '''7R''' was produced from 1968 through 1971 with a twin throat down-draft carburettor.<ref name="RT41parts">Toyota Corona Deluxe, Parts Catalog, No.53212-68</ref><br />
The '''7R-B''' was produced from 1968 through 1969 with dual [[SU carburetor]]s and higher compression.<br />
The '''7R-LPG''' was produced from 1969 through 1970.

The 7R was similar in displacement and technology to the 4R except the wider {{convert|86|mm|2|abbr=on}} bore and shorter {{convert|68.5|mm|2|abbr=on}} stroke of the 7R gave different power characteristics.
