You have aftermarket VTC cams? Who even makes them? (I have never heard of it, that's why I ask)

I've also got JWT S3s with VTC for an s14 sr. When you order them you can request that they machine them in order to retain the VTC function.

My engine hasn't been assembled yet so I cant give you any numbers.

I think price for machining is something like $35-$50

good then have them compare your dyno chart to another making the same horsepower but without VTC and lets see the results?

What you are not getting, is that the VTC only increases your torque in a part of the powerband that you would NOT use in cases where you care about going fast.

....but you are sacrificing 40-50+ hp in parts of the powerband that you WOULD use when you are trying to "go fast".

In any real "racing" situation (other than going from a dig in 1st gear, which we all spin through anyway), you will always be keeping the revs at 4000+, so the VTC stuff is not of much help.

Basically what Cody said

Ok true, if you count Autocross as racing....because you are constantly spooling and unspooling the turbo.
