The End of 30 Years Old Subaru EJ20 Production
One of the 10 Best Engines of the Year. The long-stroke engine started off with a SOHC head and an output of 113 ps. Over time, the engine went from 2 litres to 2.5 litres with turbocharging added, taking outputs as high as 324 ps and over 400 Nm of torque.
Subaru Japan had announced that production of the outgoing WRX STI had ended and with it the end of the legendary EJ20 boxer engine. The EJ20, which replaced the EA engine, started off in the first generation of the Legacy in 1989. Over time, it was offered with other Subaru models and also powered racing cars competing in events like the World Rally Championship and Nurburgring 24 Hours.
The new performance flagships are largely expected to have the FA-series motors under the hood (with the 2.4-liter FA24 to power US-market WRX STIs and BRZs), meaning the EJ25 will end production as well. To commemorate, Subaru is releasing a limited run of EJ20 Final Edition WRX STI Imprezas for the Japanese market.
