      you might / will bend a/couple of valve, for higher rev you need stiffer valve springs plus electronics that can control the fuel and ignition at that RPM

        You mean valve float?

                  The Eta cylinder head physically CAN NOT rev that high. Nothing will bend or break, it just won't do it.

                  Not even Megasquirt can make an Eta engine rev that high. Super awesome suggestion though.

                        The ONLY way to make it do what you want is to swap an i harness and computer. You'll also want the i throttle body, intake manifold, and injectors if you don't have them. Along with the i AFM and crank sensor.

                        Not sure why you're "trying to avoid the i computer. Swapping the harness and all other parts I mentioned above can be done in one day easily.

                              very different, very easy swap though. It took me about 20 minutes and 10 of that was drilling out that damn hole in the firewall
