Here's what you need to do: -Buy a new exhaust -Buy a new power steering pump and new hoses -Buy a new alternator -Buy a used radiator -Fix your fuel leak (most likely a hose or loose hose clamp) -Buy a used lock set with keys off a wrecked TT and have fun installing those. -Buy a new oil pressure sensor -Conduct the 6P's and clean your IAC assembly
If you don't feel comfortable doing the work you're probably looking at paying someone else for around 25 hours of work on your car.
Also most of the problems aren't going to go away by doing a TT swap.
"The 300ZX Turbo is a dance; it's a song; it's rolling, roaring automotive art. There is no color that doesn't suit it. There is no mood-lifting chemical substance it can't replace." - Automobile Magazine
