well there's not nearly enough fuel in it till 4K, and I'm betting it's pulling the **** out of the timing until then. First thing, more fuel system and better fuel tuning.
On another note, if it's at 10.8:1, no turbo kit is appropriate. compression is too high and you'll just bump the pumping losses through the roof and not gain the power you thought you would. If you drop the compression you'll be able to put the turbo kit on it. Requires new pistons.
