However, the JDM equivalent (Celica SS-II) had 190hp. In American/USDM trim, the Toyota Celica “GTS” had 180hp. Typically, if there is a small HP difference reported between a JDM and export version of the same engine, this can often be attributed to a different ECU/tune and also to the fact that the octane rating in Japanese fuel is generally higher than in many other countries.Ī good example of this is the 2ZZ-GE from the Toyota Celica.

Let’s say you have just purchased a Mitsubishi 3000GT VR-4 (of course only after reading our Mitsubishi 3000GT buyer’s guide). If JDM stands for Japanese Domestic Market, then it stands to reason that a JDM engine is simply an engine that was originally fitted to a JDM car. something that was originally made for sale in Japan and not for the export market.
