Yes Incubus you read right. Toda makes a VTEC killer package because when racing (read road racing) The motor usually stays above the VTEC switchover point and so the extra weight and friction from all the uneeded switching mechanicals are just dead weight. Also, since the only real reason for Having VTEC is so that you can have a racing profiled cam for high rpms while maintaining that dubious honor that most hondas have as being fuel efficient at lower RPMs. It makes no sense to use a fuel efficient cam profile while road racing since the lower RPM cam profile will essentially end up being the same as the higher RPM profile.

I know it doesn't make sense in the fact that if you were to Turbo a honda motor VTEC actually can be a benefit if tuned properly. First off if you use turbo cams it can help the motor make more power while the turbo is still spooling up while also providing an optimized performance at higher RPMS after the switchover. However supposedly if you use the VTEC Killer package you can use a single cam Profile to optimize the Turbo and motor during spool up and the same profile can be beneficial at higher RPMs at the same time to keep the turbo moving. It's debatable I know but I guess it depends on the cams your using, the motor, and your application for the car.

By the way I already said I agree with you that Type R motor are not good for forced induction so I don't know why you restated what I already agreed with you on.

As for buying a GSR Head and there being a great enough difference from a Type R head that I could buy an intake manifold, rods, pistons, valves/valvesprings, I'm not sure that is true. Compare a Type R head and a GSR head that is ported and polished and then let me know if it is still cheaper to go with a GSR head.
