OP, in my signature is a link to my turbo build, may be worth some research so you can avoid all the mistakes I made along the way.
When you choose your kit, you have to make sure you also have the correct K-Member, suspension, etc as well.
Now that I know what I know, and I have picked up a TIG, I think I would build my own kit, minus the headers, that I would purchase. But, it all comes down to budget which is a moving target.
