you've never heard of a turbo? and i bet a rebuilt bottom end with forged goods on a honda motor costs like $82. if you know how to build a 4 banger, it will be brutally fast. ever seen an inline four motor running 45 pounds of boost on straight methanol making more horsepower than all of the cars in your driveway combined and doubled? okay then.
to all small engine haters: you're weak. grow up.
