BTW Jeff did you have to add a fuel return line with an upgraded pump and an rising presure FPR when you were at 11psi (build your fuel system)? I really don't want to invest that much in the fuel system unless i'm going on to the next "stage". I'm also thinking about just running meth injection for the time being.
As far as fuel goes:
You can do a cheap fuel upgrade with a set of 550cc injectors, walbro pump, and rising rate regulator. Well it's not cheap, but it shouldn't break your bank. I did it for about $650. Involves modding your stock fuel rail for a return fitting, run a return line to the tank, put in new pump, add a FPR, and throw in new injectors. I'd say that will be able to safely carry you to around 450whp. The stock motor can take 450hp for a while, but its just a matter of time before the weak rods snap and thin ringlands break.
The stock fuel system...I wouldnt recommend you going more than 7-9psi boost with it. The factory injectors are a measly 280cc or something pathetic lol. Also you will have to worry abotut the factory ignition system past 400hp. The boost at that level tends to blow the spark out.
At 11psi, i would recommend a set of new injectors at the very least. The return line , pump, and regulator can be optional but i'd still recommend it since I'm sure you will be upgrading in the future anyways. Everyone always say the wont but they end up doing it lol. I ran on completely stock fuel when I was at 9psi and it was leaning out a bit up top already. When I upgraded fuel along with 2mm HG, I went straight to 15psi.

I really want to, but i do understand the cost of the next level...which is pretty much out of my budget right now, and i won't be able to achieve it until after this summer.
I was also told that my stock fuel won't be able to keep up with the 550s, so is it possible to throw in some 330s instead and still have my stock fuel keeping up with it?

nice write up. it didnt look like you had to trim any of the chassis to fit the piping thru.
well im thinking about boosting too, cant debate to just slap on a kit, the only thing stopping me is afriad of blowing the engine. but im considering a engine swap which is easier and no worries. but trying to go the budget way.

Very wise words lol. I wouldn't recommend anyone here to do an engine swap unless you are really really prepared for it. You can achieve very similar power results with the GE motor just by building up the bottom end with stronger internals. You don't have to worry about all the custom fabrication and such.
ElitistK, you can throw in 550's right now. Even though the stock pump can't fully fuel 550's. Maybe those injectors will only put out like 350-400cc or so at max with the stock pump. Once you do eventually upgrade the pump(cheap only like $100) they will run at full 550. No point to buy a set of 330cc now and then buy another set of injectors later. Just start big and work your way around it. The AEM FIC controls the injectors directly...that means you can tune around it all. Still I would recommend at least an upgraded pump. You can hold off on the FPR and return line for last.

wow what a great write up man ive got the same kit just waiting to be put in my car in my garage!
ive got a couple of qs for you though
::
I highly recommend upgrading your feed and drain lines. -4AN for feed and -8AN for drain
Feed list (don't need NPT to -AN adapter)
555-100050 #4 STR HOSE END PUSH LOC
555-102200 #4 PUSH LOC HOSE 5' BLUE (or whatever length you need)
Drain list
555-100129 1/2"NPT TO #8 FLARE 45 degree bend
555-100107 3/8"NPT TO #8 FLARE
555-100052 #8 STR HOSE END PUSH LOC
555-102220 #8 PUSH LOC HOSE 5' BLUE (or whatever length you need)*
*People usually run -6AN for their fuel system, but if you decide you want to flow more, then you can go up to -8AN and buy like 20 ft. of this stuff.
::
where can i find these??

SAFC is just marginally enough. I used a SAFC as my very first piggy back. Although it worked, I'd recommend against it. Think about it this way...SAFC $300 or FIC for $450 or so. Not that much of a difference in price, but the FIC is a world better than the SAFC.

1300 for the kit
200 for the 1.3mm HG kit
150 for the piping
250 for AEM UEGO wideband
350 for AEM FIC
Misc. stuff is about 200-300 bux
Total is about 2550.
Not including all the tools that I bought.
