What kenne bell setup can I safely use on a stock PI 2V motor? How much boost, intercooled vs. not. Which setup wont push me over that dreaded, motor popping 425 rwhp?

gotta order it right from kenne bell, unless your having a shop install it (ie. modular powerhouse)
the KB creates a lot of heat and to protect your engine from pinging running more then 6psi your gonna want the intercooled kit. depending on tune/other mods you can probably get by just fine with 8psi intercooled just fine

I think they say around 6 psi non intercooled and 8-9 psi intercooled (will depend somewhat on what kind of gas is available in your area). I highly recommend viewing their website and reading their tech articles. They are highly informative and can answer most questions you may have about them and then some.

Some 2v's pop at 350WHP, others can take 500WHP stock. It's just in the tune. Stay in the 425-450 range and you'll be good. Maybe 400 if you want to be safer. Just have it tuned by a reputable shop.

my buddy has a 1.7 9psi intercooled kit and he has 445 and 467. his tune is from KB and is dead on as far as the a/f goes. up to 450 should be safe. dont get a non intercooled kit. you will regret it later if you dont buy the IC now
Go with either the standard 6-psi Non Intercooled kit, or even the 9psi Intercooled kit. Neither one of them will even get you close to 425rwhp on a stock car with the standard pullies anyway. Expect about 310-330rwhp with the 6psi kit and 370-390rwhp with the 9psi kit.

How much does it cost to have forged internals , part how much ? Install how much ?
After you forged it how much power can our 2v handle ?
Thanks for the info. I hear alot of talk about the strength of the 2V bottom end here on stangnet. My estimate of 425 rwhp is just an average of all the different opinions of peak power on stock internals. I realize that that number can go up or down depending on various other factors but I have to play it super safe because my car is not only my car a daily driver but it is also not paid off
. I don't want to start a roots versus centri showdown but I must say for the fact that I can't get one to put on myself, I may lean more toward a procharger. I cant afford someone elses installation fees. Any other high quality roots blowers out there I can do myself? I like the idea of a supercharger with an independent oiling system thats why kenne bell and procharger are so appealing. I need some hot, nasty, bad-a$$ speed 
on a stock block daily driver.

Don't let the thought of installing a centrifugal blower intimidate you. Aside from tapping the oil pan, the rest of the install is cake. And even then, tapping the oil pan isn't hard at all.
As far as alternative Positive Displacement blowers are concerned, you could always look into an Allen supercharger kit, similar to the one I've got. With their use of the stone reliable GEN V Eaton M90, the kits are running nearly head to head with the Kenne Bell kits up to about the 400rwhp mark (which is pretty impressive when you consider the M90 is a much smaller blower than the 1.7L and 2.1L Kenne Bell utilizes on their kits). The Kenne Bell Screw compressors will obviously outpower the Allens M90 when you start really pushing things, but at that point, you've already reached the limits of the stock internal components anyway. I can certainly vouch for their quality, craftsmanship and their customer service (which is more than I can say for Kenne Bell). And as long as you’ve got a basic automotive knowledge, a place to do the install and a weekend to pull it off, you’ll do fine.
For further info on the kit, contact and/or check out http://jroal.home.mchsi.com/ Jim has installed different versions of the kit on 5 various vehicles now and usually can’t say enough good things about them. He’s also got a couple versions of the Kenne Bell installs under his belt for you to reference.
Another good choice (if they've got the kits ready) is the FRPP kit. The kit uses the same M112 based unit found on the ’03-’04 SVT Cobra (minus the intercooler), which again is based around the reliable Eaton supercharger. They’re good for about 330-350rwhp on their own and more with water methanol cooling and/or additional bolt-ons.
I bought my kit for $1999US, balancing cost me another $300, got the block machined hot dipped and cleaned for $500. Put the bottom end together with a friend in his garage so that cost me some beer money. Install cost me nothing, put it in myself with friends. Now it's good to about 900hp. The 4.6 blocks are really strong compared to the old 5.0 blocks, they were junk after 500hp.
Right. The blocks on the 4.6's definately aren't known for splitting right down the middle, but our problem is pistons and rods. The pre 93 5.0's had forged internals, and we have hypereutectics, which are so brittle that they have little to no tolerance for detonation. The 5.0's were good to over 400 easily before you had to worry about anything breaking.
Most people here tend to agree that anything over 400 is pushing it. However, it could be argued that anything over STOCK could be considered pushing it. Have a backup plan in case something happens. I know I will.
I am getting a $30k loan in a few weeks, and have pretty much decided to buy a KB. My only question now is whether to get the 6 psi non-intercooled or the 9psi intercooled. I was thinking of going non-intercooled, and later, after I can save up more money, I'd buy the intercooler. Does KB sell the intercooler seperate? Would you recommend getting the IC right of the bat? Suggestions?
If you can afford to do it all in one shot, it's always the better route. Yes, Kenne Bell does sell their intercooler seperatley, but it requires dissassembling the majority of your install again in order to install it. In a sense, you're doing the job twice.
Since you're still pinching your pennies, I'm going to assume you're taking a good portion of that $30,000 out for other reasons. Don't make the mistake of spending too much of it on your car like I did. I'm still paying off loans for things I don't even own anymore. And paying interest on an item only increases it's total cost.
Yes, i'm using a good chunk of it for other things, which include finishing off paying for my car, and I set aside a lot for investment. The reason I can do that is because here at the USAF Academy, they give us a $30k loan at 1% interest. They call it the career starter loan, and its an amazing deal. I'm finding CDs and savings accounts for 6% (which will net me 5%) , but i'm also considering an IRA.
However, I can't let this opportunity pass. I probably won't have a spare $5k sitting around again, so I'm jumping on the opportunity to buy a KB. With my current plan, I'll be able to afford the non IC kit, but to have enough to buy the IC kit, i'd hafta reduce my investment plan. Thats why i'm wondering about the posibilites of buying the IC later, then cranking up the boost a bit. The difference between the IC and non IC kit is $1100, and I can't decide if the interest I would get on that is better than the enjoyment I would get out of 9psi compared to 6psi.
Be smart about it.....if spending the extra $1,100 is going to tighten things up for you, don't do it. If fun is all you're after, the base kit will still provide plenty of it.
