Here`s what I would do if your car was mine.
A set of pistons for at least 10.5 to 1 then an afm cam. Why afm, because it will run nearly as good as any of the customs, and I would put the turbo out of my head. It cost too much once you add up all the changes you will have to make to the car and suspension, a set of pistons and a cam and some gaskets and you should be mid to low 11`s around $1000
