"Japanese engine runs different cam profiles and variable cam timing. With the better octane fuel in Japan, the Japanese WRX runs much more timing advance, not so much "more boost". The engine is able to make more boost down low because of timing and cam factors, not the other way around. Drivability is much better as a result. Or, as a friend said of the low speed running of the Japanese WRX, "It feels like a V-8" in comparison to the US car."

"Again by way of comparison, the American car as a throttle than can only be described as 'wooly' to use the old British tuner expression. It does not want to go below 3000 rpm, and the motor just does not feel happy at all below 2000 rpm. The Japanese WRX runs on light throttle at 1500rpm, pulls cleanly and smartly from 2000 rpm and is making good power by 3000 rpm."

"In the EJ205 'world motor', Subaru engineers have made a turbocharged engine that runs more like normally aspirated engine below 3000 rpm with a transition range to 4000rpm where it behaves like a turbo motor. It has only the quality of materials internally needed to stay alive at modest power levels"

I'll take JDM
The G block is the bottom of the barrel. It made 220hp and was used mostly in Legacy's. It had HLA's and is an old Phase I block. Some were closed deck but that is meaningless at the HP levels they can handle with stock internals. There were some better G blocks RS/RA and early WRX engines. Finding one of these is rare. Finding a low mileage USDM is easy. Mike is comparing JDM EJ205 and STi EJ207 engines to the USDM EJ205, NOT THE EJ20G
