After all the arguing, the ka building is for torque happy proud home mechanics (ME) and the sr is for quick and easy swap and go boost. There is no sense in biachin about each motor; I like both and I firmly believe the sr is peace of mind F.I. swap. To the guy who started this thread if you start building your ka you will see how much paitence you need OR you could just get the pre packaged SR swap NUFF said.
