I dont think you can do it on the KA. Show me someone who is running over 350hp on a KA engine or show me someone who is running NOS on it. I saw a pic of the sidewalls on the KA engine and there isnt even enough room to bore it out to allow for aftermarket pistons. You would have to be pushing around 17psi on the turbo to make say 350hp to the wheels and to then add a 50 shot of nos on there...your sidewalls would blow everywhere into your cylinders and then probably start shooting pistons everywhere since they would catch the broken walls and shatter your rods. I dont know a whole lot about the KA, but I know about boost, and I think that although the KA engine is very reliable, it isnt made to take that much stress. 350hp on a BUILT KA is #### good, but thats only my opinion. You want 400+hp, use the sr20, its made for that.
