I understand the best band for the buck, but lets face something here, what is the OP's history of automotive experience? does he have the ability to put a turbo system together, tune it properly, and maintenance it properly? OP if you can do this in your sleep i apologize as your first posts made it seem you were new.
IMO if this is your first build you need to do the basic NA build we laid out for you. It will be easy and cheap to build, it will be a big return for your work, and most importantly you will cut your teeth and learn from mistakes. IMO most people go to boost for return without spending the time to LEARN what makes an engine work (build matrix, tune, etc). Boost is not just blow and go, its something that you learn to control and use to your advantage. That said if you cant do a prep and clearance a head for a goal, install and tune an NA induction, and build off of it to make it more efficient, you have no place running boost.
These boost guys are always in favor of blow because they can get their quick hp boost, but if you want to LEARN dont do exactly what someone else did because all the mistakes are fixed, i.e. you wont learn that way, it was given. Every motor i build and help build i learn a ton, you'll do good to do the same.
