Thinking about trading my car for a 97 Procharged/intercooled GT and need some help

First off I have a 98 TransAm with a Ls1 and it has some mods and runs in the 12's.I've owned acouple of Ta's and had good luck with 2 of mine running bottom 11's on motor,high 9's on spray.Now I've owned a couple of Mustangs in the past,but nothing supercharged.A guy with a 97 Mustang gt wants to trade.It has a Procharger (i believe the ds1c im not 100% sure) with the intercooler(not sure what stage intercooler)says it has the 12lb pulley.Car has 102k and the charger was recentally installed.They hand tuned it with a SCT handheld programmer.The internals are all stock.Car has built auto with a 3500 stall,shorty headers,xpipe,slp loud mouth exhaust,30lb injectors,373 gear and some visual mods.I'v done some research on this sight on the Procharger and alot of people here have some good info on it.My question is what kind of rwhp will the car make and will the internals hold up with 12lbs of boost on a stock motor.I like the way the car looks but don't want to go slower than my ta.Any input will be appreciated greatly.

The ProCharger comes standard with the intercooler, and offers a stouter intercooler (3 row I believe) that is recommended, especially when gearing to over 9 pounds of boost.

You can't do a complete custom tune with just a handheld tuner (you need some way to monitor wideband O2). I would recommend a trip to a good dyno tech pronto.

102k miles is a little long in the tooth for an ambitious new blower install, but if the tune is sane and spot on, it will be OK. If the intention is to turn up the volume to over 400 rwhp (which is potentially where you are with over 12 pounds of boost, assuming the fuel system is what it should be to feed the beast)...

I'd recommend an overhaul with forged internals, and some thought given to things like the rear suspension (LCAs in particular). Keeping a sane street tune in there would probably drop a few horses, but keep it from destroying things.

Much more power than that and you start having problems, including valve float as well as endangering the stock rods. These are actually pretty tough SMALL engines (keep this in mind when comparing to your much larger GM cars), but around 400-425 rwhp the stock parts start to show their limits.
Ok.Thanks for the great info I really apreciate it.
I was wrong on the charger being a d1sc its the p1sc so I'm not sure how much that matters.I've heard from others with the 12lb pulley on it that the motor is on borrowed time.Its a hard choice to make where I really like the Mustang,but I like my car also.Wish I could just have both.
