Its really up to u if u wanna go FI or not. U certainly dont need to go FI to get close to 500 rwhp. And if u wont have a rear end already then ull need 1 with NA or FI at 500rwhp. It sounds like u have a good chunk of change into it already goin the NA route. Seeing as ud need to get different heads injectors fuel pump and alot of other small crap u might be beter off with NA as ull actually not waste all ur money on a car. Once u go FI its impossible not to want more. And with a turbo its a turn of a **** away if u have tuning software so it makes for a tough scene if u dont have alot of money to throw at it. I knwo i love mine and im happy with teh **** ton of money im throwin into it but it aint for everyone. GL man

My buddy Jarrod (RICE ETR) made 638RWHP and has been at that level for a 1.5-2years now... Completely stock 98 SS with a cam-swap (that to be honest isn't even apparently all that neccessary) and 11psi with a 76GTS front-mount turbo kit that he fabbed up himself. Chack out this video I made of him on the dyno, right click and save-as: http://www.frozenwaste.com/Frost/RPM/rice_etr_dyno.wmv
Here are some passes of him last year leaving the line WITHOUT a 2-step even: http://www.frozenwaste.com/Frost/RPM/JC.wmv

We had a 2002 Vette at the Chicago Chevy Vette Fest that made 476rwhp @ 6100rpm on our Mustang Dyno. It's build sheet was an A&A Corvettes Vortech kit, Comp Cams 26918 Springs, 60lb/hr injectors, Racetronix fuel pump, Kenne Bell Boost A Pump, Vig TC, FLP Long tubes, Magnafow cat back, and an FLT transmission. That was at 9psi, pump gas, 16 degrees of timing, and an AFR of 11.9:1. Put that car on a DynoJet, and it's over 500rwhp.

So what do you guys think that I can expect with an Eaton Magnacharger running 10psi, a blower grind Comp Cam 226/234, 598/599 w/117LSA, ported 243 heads w/72cc chambers, 90mmTB, 44#injectors, Walbro 340 pump, Kooks 1 7/8 headers w/Magnaflow high-flow cats, 7.4 pushrods, 1.7 rockers, on a forged 347cuin bottom end with a good tune? I'm curious.

LT1...not so much with 500rwhp. LS1...bring it on!
After this weekend, I plan to be around 485/490 on my FI setup. The only internal engine mod I did was dual-patriot valve springs.
My tune is also quite conservative...18 degrees of timing, 11.6AFR in boost.
I love the feel of the boost kicking in via a turbo. The exponential feel of your face becoming flat and your arm muscles tightening up as you hold on the steering wheel is amazing!

ls1/2 motors can make really good power on their stock bottom ends. The weak link is the ringlands in the pistons. Eventually they'll go even on 'safe' tunes.
Oh there's no such a thing as a budget when it comes to forced induction. Prepare to have a credit card or extra money set aside.
Once you go boost you'll wish you never wasted money on n/a stuff! And you WILL want more power, trust me.

Now when you say no budget do you mean because of breaking stuff or strictly wanting more power. I'm really interested in the STS kit. How do you guys like it? Do you think it would make an OK dailydriver????

I like mine as a daily driver. Over 70mph, it gets pretty loud with just the turbo as a muffler, but unless your foot is in the pedal, you'd never know it anything else done. Once you slam down the gas though, hold on!!
Stuff doesn't break...at least it hasn't on me. The budget thing is just that every little thing cost you more and more money. It ALLLL adds up...many times over!
Boost really is contagious. When I 1st got my car done, I was amazed at the power it was putting down. Now, I'm like...ehhh...I could use some more

I want my car to scare me, that's why I am 'upgrading' to the APS Twin Turbo kit. I figure 800 rwhp should scare me, if it doesnt then I have serious problems!
My car last dynoed at 526 rwhp thru the auto and no so efficient converter. I feel like it should have came like that from factory, lol. Just wished it stopped as good as it accelerated.

I believe this forced induction thing is going to be on hold for awhile now. I'm on my 2nd 10 bolt rearend and it's starting to make a soft, non-metallish flat-tire/airplane sound. That's what my last one started to do at first and about 500 more miles it splattered. Looks like most of the money I've saved up is going for a stupid rear end, this time I'm getting a good one.

it seems as though it's been done by many running on a stock bottom end if you're not over 600 at the wheels. I guess with that new rear end and about 5-7 psi I'd be ok 
what kind of problems are we looking at if the shortblock doesn't hold the power? just a new shortblock or complete rebuild?
