My 1995 Millenia, Upgrade? Sell?

So I want to go faster, quicker. But all I have to work with is my 1995 Mazda Millenia Base, 136k on the motor and about 4k on the new tranny, 2.5L V6 automatic. So I wanna see if anyone has tried this and failed or what. The engine makes 170hp according to edmunds.com and weighs 3200+ pounds, even more with me in it so it is severely underpowered. I would be happy if i could drop the weight to 2900 pounds and even happier if it could lose more but then I also wanna make more power.

Bolt-ons are what I obviously would go for to make more power. Im thinking 2.5" exhaust and a high flow cat, and maybe 3" exhaust after the cat, it would all have to be custom made though, Im not going to trust any universal BS. I am even considering a turbo running on low boost and of course I would have to up the fuel delivery with all neccesary parts and a tune. A wider, lighter rim and good rubber to help deliver whatever power I make.

Before I get the "just buy a bla bla bla and do a (insert engine code) swap" solution, Im broke and the turbo would most likely be from a junkyard or be hot. OR should i just supercharge it like a Millenia S and have more displacement than Millenia S as well. IDK yall let me know what you think and bounce some ideas around.
