Just incase anyone was horny over the sound of bolting on a turbo, my 2004 corolla with custom turbo kit cost $11000, which included the piggy back computer, 2 stage turbo set at 5 and 12 pounds, garrett turbo, custom exhaust manifold, intercooler, pipeing, bigger fuel pump, exedy sports clutch and a 5th injector ported before the throttle body. With 12 pounds of boost and no internal work done, just proves how well these Toyota engines are. Clocked up 60 thousand kms since the mod and still going. Currently running at 184kws at the wheels. Was 100kws at the flywheel from factory. If you can get a bolt on TRD supercharger for an Aurion or Kluger for a little extra punch, it would be a much better road to take. Not having to worry about pipes, manifolds and all that type of crap. Does anyone know what the GO is with buying a supercharger and the computer side of things? Im looking at updating to a Kluger ATM
