Hey everyone, im looking into building a rearmount turbo kit for my 2003 5.3 silverado. I was wondering what all i would need, i kinda sort of have an idea but not 100% positive. What i had on my list was the turbo, bigger fuel pump, bigger injectors, an air to air intercooler, a waste gate, an oil pump to return the oil from the turbo and tuning... What else do i need to add to the list? Im not trying to set records or anything, just want about 450 to 500 horsepower on a budget.
Thanks

 

tbolt clamps, small clamps, vbands, silicon hoses, feed line, return line, lots of alum tubing, t4 flange, remove cat(maybe), tail pipe, wg flanges, welder.

 

ive already got the cat removed, ive got pacesetter longtubes and off road y, which is the only reason i dont go with a front mount...how hard would it be to tune the truck without it actually being in shop farmtruc?
And i just got a turbo off a 2007 5.9 cummins given to me, this would work wouldnt it?

 

what fuel pump should i get? part number? and would 35 pound injectors be enough? im just gonna maybe try for 8 to 10 psi

 

wrapping the headers will help speed things up.

the turbo will work, so go for it.

as long as we get some a/f ratio reading back, we can dial it in, speaking of, you'll need a wb in the cab as well.

 

walbro 255lph.

no, you'll need more injector.

 

yea i figured i was gonna have too...i was gonna get an a/f, boost, and trans temp in a custom pod...
would the UIC intercooler be good enough for this? it says itll handle 550 horsepower?
And what about the XS Power 38 mm Wastegate?
Then a Walbro 255lph?
35 lb injectors out of a 3.8 supercharged t bird coupe?
What kind of oil pump would i need to pump oil to and from the turbo?

 

I don't think that 35 lb injectors are going to get it done for you. You may need to look at 44's or most guys run 60's. Also, You could sell your headers and do a front mount setup... I would help take them off your hands But if you are set on it already take a look at a scavenge pump... ebay has some:

Goodluck!

 

Well seeing that ive only had the headers for about two weeks now if i got rid of them id lose to much money on them...i kinda wish i woulda decided to go turbo'ed a month ago but o well

 

is that scavenge pump all i would need? im kinda confused on whether i need the pump to pull it to the turbo or to push it back from the turbo...
