goals: 300-400hp (looking at around 18-22psi no more than 22). I also wanting to take it to the track from time to time i am guessing it will run mid 11sec on slicks....i am looking at either a gt30 or gt28 turbo i want a turbo that is not too laggy but will also produce big numbers on the d-series....the last one i built i sold it to a guy and he took it to jjspec and they changed the turbo to a gt3070(i believe) driving it whenever, everyone says that they are not dependable so drive it till it messes up and then fix it. this is not my daily but will probably be driven often. I would say around 20-30 miles a day

also what are some good inner coolers? ......i mean what are the difference between a ebay and a 500hp one, i would assume flow rates and efficiency but what makes the big money ones any different, maybe a smooth inlet and outlet?
