ya the sr would be nice becus the rhd would fit the car better when people pop the hood compared to seeing a ka but as far as na ka's funk used to kill sr's and he only had exhaust headers and a tune from my knowlage so ka plus turbo means un stopable till motor pops but idk i think ill try doing a standard rebuild on a ka and doing a low budget turbo kit and run like 10 pounds daily and 12 on days i feal like racing something i think that may be reliable its only like 230, 240 to the wheels
