Automatic Bolt-on Turbo

[TRD SPEC]

Hi guys,i got a ncp42 vios[1nz-fe engine same with the scion xb]
I got my hand with a td04 turbo and an evo3 intercooler that fit well,but my question is can i bolt on a turbo without changing my injector and without an ignition timming tuning?After buying some piping,manifold,oil lines,blow off valve,actuator...i end up with my wallet having a huge diet and cannot afford to buy a good piggy back ecu,all i have now is a apexi safc[can tune the air/fuel ratio],so if i bolt on the turbo and use my safc to tune it would it be dangerous?or if i temporary running my car on low boost like 5psi?if can how much horsepower can 5psi give?and would it be any faster than stock?

The stock ECM is not setup to see anything beyond zero vacuum (beyond that you transition into boost). If you install the turbo without fuel and ignition management you will be looking at spending a whole lot more to replace your engine.

What about blitz supercharger?Because after finishing the turbo system theres a friend of mine willing to buy it for a higher price simply because it save time and he has a greddy ultimate ready,i'm very new to the car screen and since the supercharger is located behind the throttle body so can it be easily hack with just a air/fuel tuning?or do i still need a ignition timming tuning?[btw i've got my hand on some 1zz-fe injector]
