Hi everyone!
Currently have 4gen f20a4 with chipped p28 ecu. I want to make it a bit faster. What are good tuning alternatives, like intake, cams? I know h23 or f22a6 intake are bolt-on and gives some power, but It’s hardly possible to find them in Europe. What about other like f22’s or f23? I researched that it is possible to put in f22/f23 intake from accord, but the thermostat is a bit different. Also have 4-2-1 headers. Are there any other power options besides turbo or swap? Yeah yeah I know that these engines are not the best for tuning.
