How much horse power does a gsr engine come with stock? I'm talking about the gsr engine that we get here in america not the jdm gsr. A friend of mine says the the gsr that we get only comes with 160 hp when i always thought that it came with 180 hp. And are the enignes which come from japan reliable? I heard they wont last very long becasue they are set up for a very high level of octane?
