ok guys, well i finally made the move and bought a custom made front mount turbo setup off a friend of mine, it uses flipped truck manifolds, Gerret GR4202 74mm charger and 4 inch downpipe. Im in the works of building a forged LQ4 for the car but for right now i want to use my 5.3 junkyard motor to work out the bugs. the car its coming off is a budget built LQ4, cam,stock 317s, head studs,ls6 intake etc. made 81X whp on 18 pounds through a 4L80E unlocked 3500 converter.
My questions are:
My cars a 1998 so im limited to a 2 bar map sensor. whats the alternate methods of using a 3 bar map sensor besides re pinning my wiring harness for a 99+ PCM?
My HP goal for the 5.3 is 550whp on 8-10 PSI can my stock fuel lines and rails support this? if so what is the limit on stock lines and rails? i have some big plans.lol
What is the best injectors you guys are using or have used that are reasonably priced and will my PCM run High impedence injectors, if not what do i have to do to run 60+ lb injectors? or is there a 60+lb injector that is low imdedence?
I want to run twin in tank fuel pumps, I have an idea of how to wire the second one in but if anyone has a sure plan or has done it please take the time to explain to me your method it will be greatly appreciated. thanks guys

Your stock fuel rails and fuel lines will hold that power, but I will consider upgrading your fuel lines and fuel rails for some high flow returnable fuel rails not returnless before trying to push some more boost, could cause damage to your pistons if too much boost is increased with stock fuel lines. It all depends on the tune also!
As far as 60 pound injectors you should be good with 60lbs injectors![Happy](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_stretch.gif)
And you could upgrade your fuel pump for a twin pump that way if you have bigger plans (which as I read you do) youd be good and not worry about it later, just make sure it meets your requirements... That also includes upgrading your fuel lines and fuel rails for higher flow rails
I really cant help you out on the map sensor part lol I dont have lots of knowledge on that topic, hopefully somebody will help you out![Happy](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_stretch.gif)
Hope some of this info helped a bit
