I thought you wanted it to be streetable.
The truth hurts, 225WHP from a N/A D16 is...how do you say...damn near impossible.
With all the stuff you listed I'd be happy to see 150WHP and still be fairly streetable. All that is going to cost mucho...
Or you can take about $1200 and scour the internet for some used turbo parts and make a kit that will put out just as much, still be reliable, still get the gas mileage and take only a few days to install.
Just my $.02 since you asked for opinions.
