What would that GT3 engine have that your engine doesn't and how much more horsepower Bypro?

1st & foremost GT3 engine doesn't have compatibility with a Boxster chassis. I'm sure it can be adapted but not economically feasible. 996 GT3 engine has simular torque output to my engine until 5000+rpm where the GT3 engine is designed to excell thru higher flow heads & cams. GT3 also has stronger crankcase parts & drysump oiling.
GT3 is rated 375 HP & 285 ft/lbs torque, in a 996. In a Boxster it will lose approx. 5% of that power & much more in smog legal form.
