Subaru JDM Version Engine Guide

Updated: Jan 8


There can be a lot of confusion about JDM engine codes and version numbers so we thought we would list out what means what. This is a very general guide but should provide some insight.

Version literally means which version of the Subaru Impreza it is. V1 is the first Impreza built, V2 is the second Impreza built, etc. The Version number was mostly used in JDM Subaru models though they stopped labeling them as V1 or V4 after the year 2000. If you are importing a JDM engine and the importer calls it a V7, V8, V9 or V10 - make sure to figure out specifically which year of car the engine is coming from. For help in determining which engine you have please take a look here.


NOTE: As of January 2021 we are longer wiring Version 1 through 4 engine swaps. Customers have had problems not only getting the swap going but also keeping them running due to harness condition issues/availability as well as the lack of replacement parts, tuning options, and not passing smog. We highly suggest if you are looking for a swap engine to check out these options.
