Theres more than a few LS1s around here that run 150 on stock pump and of course stock bottom end. This is with all available safety measures in place, good fuel, timing pulled, and some TR6s. The only time Id watch out for this is in really hot weather where detonation would be a bigger possibility.

I have heard of a guy in orlando spraying a 200 shot on his t/a stock no fuel pump. Doesn't mean it is right but I haven't heard of him blowing it up yet.
I tried the 200 out on my car at it just blows the nittos away at any speed.

the 150 puts a real strain on the fuel pump. it's hard for it to keep up. you can run a 150 without a fuel pump, or a larger shot, but you run the risk of running lean and not knowing untill you are up in smoke! a inline pump is cheap insurance....along with a fuel pressure gauge.

Don't waste your money on an inline pump. Get a walbro 340 intank pump or the Ractronix setup. FWIW, I ran a 150 shot for over a year with no safety features. Was I taking a chance? Yes, a little 1 in my opinion. Considering my experience with nitrous, I wasn't too concerned, until I put H/C and a couple more boltons. There is only so much your stock bottom end can handle. If I were you and a lil concerned. Install TR6s, install intank pump, and setup window switch and fpss and you should be all set for a 150 shot with out any worries.
I have seen stock cars run fine on a 150 and I have seen stock cars run out of fuel on a 100 shot.To be honest with you every car is different.Even though they have the same fuel pump some of them are weaker than others.I know guys spraying a 250 shot on a stock bottom.I dont suggest it but people have been known to do it.Some people can afford to take the chance some cant.My self I can afford it but why tear it up if you dont have to.
Thats why I always give good safe advice.It doesnt mean you cant go further.It just means you are taking a risk. Ill let the dare devils wonder out there on there own.Ive done it.When it comes to most people they want the good safe advice.If thats what you want im your man.

Well I ran a 200 shot on a single stage NX Gemini twin MAF kit on a stock lower end with out any problems. I would suggest all the saftey features, window switch set at 3000 RPM on the low end, WOT switch, FPS switch, a Walbro 340 intank pump, 2 degrees of timing for every 50 HP shot, A/F set rich 11.8:1 or better and good bottle pressure, at least 1000 PSI but I prefer 1150 PSI. 10.08@136.7 with a shitty 60ft.
