503e was intended to be Toyota's engine for the still born Group C Formula (Jag's XJ220 was designed primarily for this formula aswell). Upon the announcement of the IMSA series, Toyota and Dan Gurney (motorsport LEGEND) joined forces to create the all dominating Eagle GTP car.

Possibly the most important attribute of 503e, was the installation of oversized water jackets surrounding the exhaust ports.

can't quote as fact, but the 503 was the race inspired version of the 18RG, but equipped with the 16v head, with later became the 3STG. the name '503' was possibly just an accession number through some trial and error on the project, much like the 2TG derivative of similar title.

a little googling found one that revs to 18000RPM and was ~1650HP... so there are some who think that this is not enough.
