The older body style probes did come with a turbo version of the 4 banger. The newer probe GT's came with a 3.0L V6. Although I never did drive a GT I heard that it was a very smooth V6.
I like the newer body style probe and would buy one as a daily driver. 5.0 HO is right though, I wouldn't put any money into it.
You'd have to sell the farm to get alot of performance without using Nitrous. And even then I would rather buy an older fox.
But good choice for a daily driver. My mom had the 2.0L I4. It was a nice little car.
