This Honda Civic Si was built by Emmanuel Burciaga of NA Performance, and is currently making 330 horsepower from a high-compression 2.5L stroker engine running Ethanol blend. The parts list is ridiculously extensive, and while this isn't a project Emmanuel recommends for his customers, it's a testament to the kind of speed and power possible without turbocharging a Honda engine.
