There really isnt a lot of options for the stock KA engines. One company (XS Engineering) I think has finally released a turbo kit for the DOHC KA(around $4000). The KA is a big 4-banger and can put out some decent numbers at just 6psi. I think the kit makes around 240hp at the wheels. The best way to go is an SR20DET swap its expensive though.

SR engine is good for around 400hp on stock internals. Dave with the SR swap(dont think he is on this board) recently ran a 12.4@116 with larger turbo injectors etc.
