D-1sc with stock bottom end
Most people who don't do enough research and only see guys like the OP and think that they too can get away with it problem free, and thats just not the case, so it should be stated and known that this is not something one will "get away with" on a consistant and reliable basis.
I honestly wish you the best of luck with your car. But you have to know that it will go on you sometime, and that you are way past the safe limits of "boost abuse" you are putting it through. To say you pushed it that far in my mind isn't really that impressive, as you could just as easily sprayed a 300 shot of nitrous on a stock bottom end for big RWHP gains and track times, but I doubt you'll achieve 30,000+ miles with the setup before something goes
Do your combo as a daily driven car with WOT here and there consistantly for years without engine problems and just as many miles as would normally be had on a NA car until you are in need of a rebuild and then I will be impressed.
Hey I no what you mean man I am in the same boat as this guy with my car it is a stock bottom end to. But it is no big deal when she goes for me I will just build it bigger and stronger. BUT until then I will just have fun with it.
If you are going to boost a stock bottom end, this is the attitude to have.
I think most people know boosting a stock bottom end is risky, and I'm sure most don't care if the bottom goes on them cause they already know the risk factor like the guy above you posted. I feel these stock bottom ends are fairly safe on low boost meaning anything under 10psi for a CERTIAN PERIOD OF TIME, but like you were mentioning before, how long, No one knows. It's like anything, beat the **** out of it and a naturally aspirated car wont even last. Drive more conservitvely and respect the car and you'll probably have great results N/A or FI.
People just want the power gains you get from FI. The correct way is too build your bottom end and then purchase a blower/turbo. But quite frankly, most of us are on a budget of some sort and the bottom end decision is usually the last upgrade. Who has a solid $20,000 to spend on mods at one shot because until you purchase a blower/turbo kit($5,000 +) ((bottom end, probably upwards of $3,000 easy)) heads(at the minimum $1,200), intake, fuel system and whatever else, suspension , rear etc. It gets way out of hand.

10 LS Engine Myths That Refuse to Die
Verdad Gallardo I know what you are saying, but none the less that is the boat you are in. I disagree though that a NA car won't last a long time if you beat the **** out of it. A well maintained car that doesn't have abuse on it that it was not meant for will last for a very long time. This goes the same for FI.
I know several guys who are NA with a big cam and a nasty set of heads with 150,000+ miles and still going strong. I plan on my FI engine lasting at least 140,000+ miles as well before anything major goes wrong as my engine is built for the boost.
Now, you beat the snot out of a stock bottom end car with boost (say just 8#'s), and you'll consider yourself lucky if you make it 25,000 miles, even if its maintained. The abuse the boost puts on non forged internals and a high CR is just too much.
To say that the power that can be made going FI is appealing is obvious. But take in consideration that even boosting 8#'s with the supporting mods needed will still cost you thousands (figure $6,000-$8,000 all said and done). And then you're going to have what, maybe 375-440 at the wheels unreliably (without other mods)? Not even close to what I would call cost effective when you can get an awesome heads and cam and intake combo for like $2,000 and would probably net you the same RWHP and it would be reliable, as in something that would last for 100,000+ miles if maintained well.

There is no real cheep way to go fi the way I see it. The way I have always done it is one up grade at a time that way I can see the improvement and still have some time to drive my car and have fun.
Don't worry CALL911, it may seem like I'm trying to go against everything you're saying ,but I'm not. I do agree with you. It was just cool seing what the OP did with his car and all. I'm really trying to figure out myself what to do to the car next after I get a tubular K member yet. Do I get heads to support my cam(G5x4) and make only another 50rwhp at most or get some type of FI kit, and make probably an easy 80+ rwhp with a low boost setting. I'm in no way expecting to get 100,000+ miles out of my stock bottom end by any means. Just always wanted a blower or turboed car. And yes , I know, the G5x4 cam is not by anymeans a FI cam. But I like it so it will just have to do.
Any cam will work with a blower. The question you need to ask yourself is; "Is spending thousands on something that will possibly make my engine go boom and not give me much extra HP for the $ without going Kaboom for sure early worth it?".

I dont think you can generalize like that.
If it's built right (IE proper fuel system, pcv, etc...), tuned right, and not run down the 1/4 mile a 100 times a week or rev'd to 7,000rpm daily the motor can last a good long time at 8-12psi / 500-600 rwhp.
50K and counting.... and believe me he doesn't baby the car. Every time it's driven it sees full boost a few times during the drive. He has no self restraint
Oh and PS, the system was put together for about 3K and currently puts 650 to the ground to boot
Definetly the exception to the rule but it can be done if you know what your doing and can come across some great deals.
Not a bash on what your saying 911 as most people dont do things right and your comments definetly hold water for that group. Just a post to support that what 408 has accomplished thus far can be totaly true and not some internet fairy tale.
Then the 50K plus on my buddy's TA thats been running between 9 and 13psi for those 50,000+ miles must be a miracle.

For every one success story like you buddies T/A, there are 50 stories of guys that fried a piston before their next oil change.
You can say its fine, and reccomend it all you want, just as I will reccomend against it. In the end it's all a gamble unless its built for the boost.
If you are refferring to "being done" as hey look, I just put a 300 shot of nitrous on a stock bottom ended LS1 and my car hasn't blown up yet, then I would agree with you that not all will grenade themselves right off the bat. It takes "some" mileage and abuse. However saying it in this sense even though it hasn't blown up yet, doesn't mean its what I would call "successfull" or anything you can count on when traveling more than a few miles away from your local shop.

Lots of people know what they're doing, but all that does is lessen the risk of things going boom instantly. Knowing what you're doing does not mean you are guaranteed to not blow the bottom end. That's a lame reason for support of an arguement.
I concur! Even if you "know what you're doing" you can still make bad choices and run the same risk someone who doesn't know what they are doing with running a similar "risky" setup.
