I think I can feild this one.
Most will tell you that it costs far less money to sell the NA and buy a TT. In most cases they are right. A "COMPLETE" TT swap will cost about 5k using used parts and about 10k if you pay someone to do it for you. Figure 5k for your car + 5k for the swap = 10k you could have spent on a TT

With that said. It can be done for less but you have to have the know how and tools to get the job done. Can you weld? Can you solder electronics? Etc.
It's a rough job with lots of downtime and NOT for everyone.
