93 mx-6 help please

Yes I'm new to the site and I hope I'm able to do this here. I'm currently in the process of buying a 1993 mazda mx-6. But here is the problem...I know a decent amount about my honda engines but I have no knowledge about the engine in this car i'm about to buy or any mazda for that matter. The car I want to buy is a riced out 93 mx-6 with a 16 valve DOHC with a garett turbo that HE SAIS is tuned on a dyno to 32psi and has fuel injectors that are open for 80 milliseconds more. My question is can this motor even hold that psi even if it's been built in the first place and LAST? Most cars with that much boost built would still rip the engine apart. He say's it's been built but 32psi is a lot and I'm just scared I'm getting into something that's gunna cost me down the road. How much Horse would that be running on AVERAGE if it's tuned to 32psi and say it's built properly to handle that?

I haven't been able to ask him what's been done to the engine other then what I mentioned he wants $3000 for the car it needs paint that's it.
