The Hooligan

hey guys im building a turbo kit for my dohc zc cause i need some more power and a turbo seems like the best and cheapest possible way of doing so. so far here is what i got.

89' mx-6 turbo,downpipe
93' rx-7 bov
hf manifold

stuff i need and plan on getting soon
oil lines
dsm 450s or stay stock?
fuel pressure regulator
fittings
intercooler
intercooler piping,silicone fittings
gaskets

im trying to run a very basic cheap kit to get me goin and upgrade in the future. things im wondering is if that turbo is gonna work for my application. some people are saying its comparable to a t-25. that would be fine for me cause it would spool up pretty quick and take care of business. im trying to get a reliable kit and keep it at about 6-7 for daily driving and 8-10 for track days. my main question and which os the most important is what i should do for tuning. plans were either the avc hack or getting a turbo program chipped om my pm6 ecu. any help will be greatly appreciated.

just so u dont have to read all that, is this a decent turbo choice?
should i use 450s or will stock injectors give enough flow?
can i get away with just increasing the fuel pressure to daily drive until i get a proper tuning program?
