First, hi to all - very helpful website

I own a 95 Manual non-MIVEC with a 6A12 GR, and am looking at my options. I see there is a ton of information here, so forgive me for asking this.
But what would be my most viable option? Slapping a turbo on the side of the current engine or what I quite like the idea of is the 4G63T... or the seemingly much more popular 6A13TT option? I like the idea of the 63T as there is a ton of aftermarket options available for it..
