By saying that, you haven't done ANY research into the process whatsoever. Give it up. Stick with a non-turbo first. Move on to a TII. Get an FD when your comfortable with the TII. Build a sick fast 13B. Do the 20B last. You have NO IDEA how long it will take, and what type of fabrication you will need to do. Just with Dragon doing his conversion in the shop, I can GUARANTEE you that your "two mechanic friends" have NO idea what they're getting themselves into.
