Need 2.3L advise.

It's not as simple as slapping a turbo on the current engine, unfortunately!!! The internals in it will not hold up to the boost pressure and you'll fry the engine, fast. A 5.0 swap is a nice idea, but not nearly as simple as swapping in a 2.3 turbo motor from a Thunderbird. These engines were made to handle the boost pressure and they essentially drop right in, with only a few wires needing to be repinned. Buy the 2.3, with 86K, it has a lot of life left, so you don't need to do this immediately. Do some research on here and www.turboford.org and you'll probably end up wanting to do this. Many on here will echo my suggestion. Buy the 2.3 and gather parts, or simply buy a parts car, to get a 2.3 turbo motor. Once you get all you need, swap.
