Whoa…I dont know why or how but I didn’t begin reading from post #1… LOL That was strange… Oops
Anywho…on one hand I want to discourage you from investing so much time and energy in a 94’ Plymouth Sundance…and on the other I respect your Gumption and willingness to wrench. It seems you are capable of doing whatever you want mechanically so…just do what you want.
If it were me? I’d start seeking out parts from a Lebaron Turbo or similar Chrysler/Mitsubishi engine…build yourself a high boost sleeper. Something like that…surely you dont want to do all this in stock formation?
I mean this vehicle is essentially worthless unless you find some kind of attraction or what have you with it… It would not be worth 1000 dollars in engine mechanicals etc… So I’m not sure what it is you are attempting here…are you trying to piece together something on the cheap, saving money using your skills? Nothing wrong with that… But dont go spending big dollars here…because there are far better platforms to begin with and with your skill you can turn it up from there.
