Porting a gen 3 blower and LIM can be beneficial for those with an IC, but bypassing what gives you the power seems like it may have the opposite effect of what you are looking for. That said try out the BBV mod, and see what effects it has. If your car is like mine and it doesn't give you knock, then you will quickly find out the result of blocking off the BBV. Then you can figure the opposite may be true in opening it up further...
disclaimer: most of the time I don't know what I'm talking about...so experiment at your own risk.
