1995 Millenia, Upgrade or 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.  

Honestly, I would sell it and get a better base platform.  The automatic trans is a major weak point the car is heavy.

Your parts list sounds about right, but you should work on the suspension too.  I wouldn't suggest a turbo from a junkyard though, unless it's only been there for like 20 minutes; additionally, you would need a whole kit, and one that would fit your engine too.  As for a hot turbo, that is a load of BS.  You don't buy a turbo that has been stripped off someone else's car unless you would enjoy having your own car stripped.  

who would strip a millenia though? = ) yea i know i would need to upgrade the suspension too, but im looking at it now and its just so much money to sink into my grocery go getter. im just gonna buy a junky 240 or shell and rebuild it from the ground up, but do a silvia conversion on whatever model i can get. cuz i mean, that is my dream car.
