LS Motor

LS Motor?? It has a 9.2 compression ration if i were to prot and polish the intake manifold and head and get a 5 angle valve job along with boring out the bottom to a 1.9 litre and adding eagle rods with je forged pistons and then adding a Drag 3 turbo kit. What would i be looking at for compression? horsepower? and how much boost could i run ??
