I wouldn't worry about all that. There are a few "different" people around here. It's part of the charm of the board. Anyway...
I am new to the turbo scene as well. I am almost done installing a Cartech SS kit on my 94. I didn't buy it from them, so, as I have said, I can't comment on their delivery times, promise keeping ability, etc.
I can say that the parts all fit. I did cut a couple of small holes in my fender to make it easier to get at a couple of bolt. I also removed a small bit of "extra" metal (nothing important) to make the intercooler plumbing run easier. Also, I got rid of the air pump and associated plumbing. The rest of the install went very smooth. All the parts are good quality. I did cut and re-weld the intake tube so that I can still use my crossmember, but I do not think Cartech intends the crossmember to stay.
Now, I can't answer your question about the amount of power it will make. Hopefully next week I post something along the line of "This turbo kicks ***". The kit I have has the upgraded T-64, and that turbo is rated to around 750 hp, as I recall. There is a sticky up top that gives that info. The guys at JMS (they are doing my chip) run turbos, and they say that at 10lb of boost, a turbo is good for about 50 MORE hp than a supercharger. I have seen plenty of guys running 8lb superchargers making 400rwhp with aluminum heads, etc. With my 306, forged pistons, etc, I am anticipating 400 - 450 rwhp. I my run into some cam problems, as I hear the stock cam is great for a turbo, but we will see. Anyway, with a 347, I would say 500rwhp is not out of the question. That is more than enough to break a lot of stuff!
I just reread your post - a 347 with stock heads? That seems like an odd combination. Did I read that correctly?
1990 LX Coupe 5.0 5 speed w/ 2000 Exploder GT-40 engine, P heads, mystery cam (F cam per previous owner) 3.73, and not much else. In the parts pile - UPR tubular K member, CC plates. Future plans - Megasquirt & On3 turbo system.
