What engine do you currently have in the truck now?
If you have a 2.3 already, then you don't need a 2.3T out of a Tbird to do the swap. You can build your existing motor to turbo specs.
What year is your truck?
You won't have to make a custom exhaust manifold for the turbo, Stinger (www.stinger-performance.com/
) makes a great header and downpipe for the ranger.
Bob Lee (40bob.com) makes one hell of a header as well, and will customize it to your specs too. (within limits)
Don't expect 450HP out the gate with either engine swap though. You'll have bugs to work out of either swap, it's best to start with a swap as close to stock as possible to help avoid all possible problems and hickups. Then mod from there as you work things out one at a time.
