4age turbo? 4age? 7age? 4agze? or 7afte Options

[MonsterBOX]

I have the ****ty ST...i can't afford a 3sge or 3sgte, its too much cash to do the swap and the tranny and the wiring is hard so instead I want to go with an easier route....i know most people with the 7afe put the 20v 4age head on and they end up with a 7age but they get low revv and only gained hp in the 5k range...is it better the just switch out the whole engine with a blacktop 4age to ur st tranny giving u 165 at the crank? and is it possible to turbo charge this in the future? Other get the 4agze but it only pushes 165 in the low end so isnt it better to have a black top with same hp and without the supercharger...i just dont know what to do...i need a reliable engine cuz my 7afe is bout to die...
