It appears you're fairly new, so I will answer your question as well as point a few things out for future reference.

1. Sell the car and buy a TII. Seriously. This has been beaten to death 1000 times over the last 20 years and the answer is always the same.
2. You need to search. Again, this has been covered so many times there are dozens of multi page threads bantering back and forth about this topic.
3. This is a build thread section, not a Q&A section. The thread will be moved by a mod, if not deleted. Being as you're so new, you should be posting in the new member tech section if you insist on making a thread. When you're experienced enough to be posting in the main tech section, you will be ridiculed for not searching and asking such a question.

Your first thought is going to be "I don't want to sell my car and I want to have the satisfaction of building it myself". Everyone says that :). You will spend more money and have a worse car than if you would just sell the car and buy a TII, like everyone will insist. If you decide you're still smarter than 99% of everyone else before you, you can search for Aaron Cake's website where he did an NA-TII build. He's perhaps the most infamous and documented individual to do the conversion well.

I wish you luck and I hope you get the power you're looking for. Just please, brush up on the topic before you proceed any further.
