I don't think you will notice any significant gains in Horse Power. Marginal at most in a street car with low boost and muffled exhaust. I spent a lot of time on mine, way too much. This was for a different purpose. I wanted to try to reduce pressure from the turbo to the combustion chamber. I am running a dinky RX6 kit. From the research I did before I purchased it, it is getting out of its efficiency range at around 14 - 15 lbs of boost. This means that for every extra LBS. of boost you will be creating LOTS of heat compared to a larger turbo. There are tradeoffs for quick throttle response. I went over and beyond to try to reduce back pressure because of this.
The easiest thing and most practical is to pin the upper intake to the lower ( so the ports are in a fixed position ) and then match the ports for about 1 - 2 inches. ( Where the upper connects to the lower )
