The reason those little 2-3 liter motors can run such big turbos is RPM. They spin 9-10000 rpm. A lot different than a big block that goes 65-7000. On my last setup peak power was 5500 rpm with 7200 rpm shift point. Most of the import 6's have a 4k-7k power band. The only cars I have seen that run over 9000 rpm are non turbo rotary motors. Oh cool. My buddy runs a turbo 4cyl eagle talon and hes in the 9000 range with a 80mm I believe..
