Sell your NA and buy a TT. Even doing the labor yourself and bargain shopping you are going to spend 5K minimum and likely much more. After all that money and time spent you are going to have a bare bones swap. Clean relatively low mileage TT's can be had for ~6k and it wont take hundreds of hours of labor and headaches. If you want the experience buy a Z to part out and learn that way. Take the money you earn doing that and add that to whatever you get from selling your current car and buy a TT. You'll end up way better off that way.
I own a swapped NA to TT car by the way. The previous owner did it but looking at the receipts make me cringe. 10k+ for parts and labor not including the initial cost of the car and several mods. That was pretty much an NA to stage 3+ TT swap. The only reason a swap makes sense is if you want to go all out and build a monster while completely restoring the car or if you want a TT vert or 2+2. There are a lot of benefits to a swapped NA but trying to do it on a budget is stupid.
