Dude.
Yes it can work, yes it can make a difference, but no, it isn't going to be simple or easy.
You need two things to pull this off:
knowledge and skill.
Mechanical skills take time to develop, even then you need an aptitude. Only you can decide if you have those skills.
Knowledge is also aquired, but not from posting questions on a board like this. No one wil lbe able to guide you through it because it will be a custom installation.
Your project is going to be basically a one off type of deal.
You need to get books on turbocharging, supercharging, fuel injection, and type 4 engines and study them, over and over.
Then you will start to develop a clue about how to pull this off sucessfully.
I hate to discourage anyone but if you don't have the skills and don't want to spend the time to do the homework, you will fail.
I speak from experience.
I turbocharged a type 4 914 from scratch, I have a non-stock turbocharger on my 911SC, I built a supercharged chrysler hemi in the 80's.
I was sucessful only because I did my homework. For years i was like a sponge, searching for and absorbing every single bit of information I could find. Eventually it all made sense.
You can do it but you need to become an expert on the subject BEFORE you start the project, not after you give up.
BTW, I gave this same speech to a few members of this board who were planning to start some unusual projects over the past couple of years.
At least one of them did what was necessary and his project worked out very well.
I toasted his efforts and raised my glass to him. You know who you are
One of the others did not complete his project. I doubt he ever will.
