I am wondering what all is involved in taking a NA and converting it to a turbo? I have an 88 924S and a Subaru STI turbo. I want to put them together. I plan on doing this in 4 months or less. Does anyone have a good write-up of this procedure?

well
obviously for starters you would need to have someone build you a custom exhaust manifold which will accomadate the sti turbo. Also you will need some kind of stand alone fuel and probably igntition setup. And I will leave it to the turbo guys to fill in the rest for you. But seems like it's alot of work and money. It would be more cost effective just to buy a 951 or 931.

I am not worried about the cost!
I am a 17 year old with no bills and a VERY good job. I thought about using some of the parts off a 944 of the same year. What do you guys think?

Without knowing your skills I would say take it too a shop and have them do it then.

If you have no bills and the paycheck - then sell it, buy a 944 Turbo, and spend your time and extra money modifying that. The end result will be better. You'll spend so much time trying to redo what the factory already figured out. I doubt the STi turbo is even that well suited to the 2.5L motor.

Consider a different engine swap; the 968 3.0L motor has been done, into the 924S, and seems like an excellent upgrade. I may someday do one myself, to one of my turbos.

Other ways to waste your money? Well, you could always go racing. Or try doing something different. A coworker of mine is finishing up the install of an STi drivetrain into a 914 2.0L! RWD, of course, but otherwise complete.

OT: wow..that will be something to see going...914 2.0L AWD.

Yea...if you dont have bills buy a 944 Turbo S and you will be more than satisfied !!
That is the ultimate 924 (except the 968 Turbo

)

and....for lunch the porsche 944 turbo generaly prefers ferraris altough it is known ocasionaly to snack on corvettes..

I am attached to the car and don't want to just get another one.
I have a fair amount of skills (just none in drivetrain).
I can do basically what ever I want.
Can 944T intake and exhaust parts be used to make a 924S-T?
Renegade hybrids does the 914 2.0 STI. They have some cool videos of what one do.

Thanks for the interest.
I am new at this and not sure how to say this but here it goes:
I bought this car because it is beautiful and different. It is the only one in my town and I want to add more power. I don't know what to do but I have a lot of people that want to help and I work at a parts store. I have money to spend on the car and want more power. I don't want to just buy a fast car.

It is one thing to just buy a fast car, and another to build it!!!!!

Is there a kit out there or does this mean three months of the car setting in a garage while every little piece is made?

remember your not dealing with a lot of bolt on parts here for a ford or GMC engine. everything you need will basically have to be custom built. As for possible horsepower, who knows, but if you want cheap horses go buy a chariot.
