Cars are all different my turbo honda has a 1.6 engine and makes 333whp at a scant 12psi, 91octane and cast pistons, been this way for nearly 3 years now, the ej motor simply dosent have the volumetric efficiency, also evo's all have factory twin scroll which helps. Suby is dual duty car but more well mannared and street oriented...
