"Building a motor" does not make you more power It ensures that your power adder isn't as likely to blow up your engine. Once you build the KA for the cost of VG turbos, you still have to buy a LARGE turbo for your KA to get the same top end power as with a diminished low end. Meanwhile, I pull my engine, put on two mildly upgraded turbos and put it back together and run your numbers all day with lots of low end fun torque, but enough top end to kill Vipers all day at the strip. >"Kill Vipers," just an expression. Don't try that at home<
