It can be done. It has been done. The MAIN reason most people don't is......

The extra pressures in the combustion chambers on an engine that comes factory with 9.2:1 compression ratio (vs. 8.0:1 in turbo engine) will cause BHG quicker than it should.

I suppose it may last a while if you keep the boost down to about 5psi.....but why spend all the time & $$$ for a not much faster motor.

You really need larger injectors too.
