1994 ford mustang. it has the 3.8 v6. I want to put the 1990 thunderbird motor into it. also a 3.8. other then plug modifications and bybass all the fancy ai sensors, what will I need or need to do?
All my time, my budget is fair.To the OP, what is your budget for this project? How much time are you prepared to devote to this project?
How much experience do you have custom tuning and fabricating?
How do you expect the car to drive when done? Like a factory car or a race car? IE will your Wife/GF be able to drive it?
How did you plan on handling engine management? With the factory PCM or a stand alone engine management computer?
Does the car have to pass inspection?
Does the AC need to work?
There are tons of basic differences between the two motors. Differences that make them very different motors. One is from the speed density days where the other is from the mass air flow engine management strategy. So this is anything but a "plug and play" swap.
Anything is possible given enough time and $$'s. But before starting down this road, at least research a purpose made supercharger "kit" for you car. Going the kit route could mean driving your project after a couple of weekends verses looking at it in the garage for maybe months/years.
