I want to leave my m3 e92 with + / - 500hp without installing superchargers or turbochargers. I want a project only aspirated.
I thought of installing air filter K & N sports, polishing collectors, sized titanium exhaust, NGK Iridium plugs, gasoline podium, remapped ECU, forged pistons and perhaps to increase the rate of cmpressão. What do you think?
