I need help!!!!!!!!!!

Ok, first off I would like to thank everyone for taking the time to read this. I am a new user and have never used one of these ever before. So I am in need of help! I just bought a 1997 Toyota Supra from a friend who's parents separated and his mom ended up getting the car from it. They bought the car brand new and have only put 92,011 miles on it since buying it. It's auto, all stock, and turbo'd. I really don't know much about the car because I have always owned and been interested in American muscle, ( no offense guys). I have a 98 ta ws6 that I did a 383 to and it's a blast to drive. The reason I got the supra is because she needed to sell it fast and I got the first chance at it. I bought it for $4900 including shipping! I was wanting to know how to mod the car? I want to do a 3.4 to the engine but I don't know what or where to get info for mod'in my car. I really don't know anything about the supra. So if you guys can help me out I would really appeciate it and I will post picks of the car soon, thanks!!!!!!
