    single turbo on 98 silverado?

    alright guys/gals heres the deal.

    i've got my 98 1500 silverado that needs an extra geddy up and go for the road and for the drag strip.
    its got a 5.8L vortech(rebuilt not too long ago 34k) all manufactured parts which isn't cutting it out for me.
    i've been lookin all around and have found estimates for hp on my truck to be 250bhp & 325rw and i want to get around 400hp & 475-500rw
    i'm not too sure wether or not if i should get an engine mounted or lower mounted turbo system its a bit ify on both sides.
    room is a problem in my engine compartment and so on and so forth.
    i know i will need a tune up to get around that hp, new rods gonna try to get some forward mounted shorty headers(becauseofspace) and any and all other things i need.
    i know buying kits are cheaper but i want this a custom kind of fit for my truck.
    i know that i need a .64 a/r from end of header to hot turbo side but not too sure what i should get.

    Any points,anyone or anywhere ya'll know of that could help me out?
    any personal experience?
    anything will do.
    thanks.

    Just buy a kit. Saves you all the hassle. Comes with everything you need.

    What good are headers going to do if you're building a turbo system?

    Fuel system all depends in the power goals that you have for the truck

    Absolutely nothing.
    Well it could also be considered a waste of money.

    The 96-98 Vortecs are pretty much unupgradeable as as far as fuel systems go

    You could put a holley steath ram intake on it, you'll have to drill it out to get it to bolt to the vortec heads. Then you can run conventional injectors. You'll have to splice the injectors in to the harness, and lengthen the wires for everything else(TPS,IAC,MAP,) and ditch the EGR. You could put an inline pump in. or run a walboro intank. But this kinda setup isn't cheap.

    They don't make bigger stock type injectors. I suppose you could run a stand alove injector driver, and mount a couple injectors in the intake but it would be difficult to tune to say the least.
