Turbo route is quite expensive but bang for the buck, it is the better of the two. N/A buildup costs a lot of money to acheive the results of a basic turbo kit. The price of what you want to do would be well over 2k and you wouldn't even be close to 200whp, whereas, my Greddy kit is putting down 215whp @ 8 psi after about 3k worth of parts and minimal tuning. Unless you have a trust fund or shit out money, N/A probably isn't the best route to take if you have high HP goals.
