Turbo 5.3 Need advice
I am currently in the process of finishing a 5.3 swap into a G-body and I'm stuck on my fuel system. I'm running a stock 5.3 with new rings, new mls head gaskets, ARP head bolts, TBSS intake and Fast 90mm tb. I bought the Msd inline fuel pump http://www.speedwaymotors.com/LS1-Co...Kit,41792.html thinking i was just doing a swap,
now i have a bullseye S372r turbo
Compressor Wheel Inducer 72mm
Compressor Wheel Exducer 105mm
Turbine Wheel Inducer 83.4mm
Turbine Wheel Exducer 74.3mm
Turbine Wheel Trim 79
Horsepower Rating 900hp
with a 1.0 AR housing
i'm planning on running around 15 pounds and running E85. I would like to know what pump would be ideal for this setup and have room for upgrades. i want to run a tu0 from speed inc in the near future. i also have ls2 injectors but i heard there is company than can make the injectors biggers. Would you guys recommend that or should i just buy new.
I would also like to know what size fuel line i would need, im running the stock fuel tank, thought about a fuel cell but i think ill get my gasoline robbed at night

I would run at least 1 bosch 044 fuel pump. but ideal would be 2. I am running 2 extrernal bosch 044 fuel pump to feed a 79mm turbo 5.3l with 80# seiman deka injectors. the fuel system is cost effective and will supply for well over 1000hp.

Two 255 pumps side by side in stock fuel Assembly and relay with large hot wire to feed them . fuel line will be limiting factor before the pumps ,$250 parts to build the setup.fuel line size -8 (1/2") if you want to save your cash you can use your stock 3/8 fuel line as return . that will support 1000hp or you could just buy a kit . depends on how deep is your pockets . i did it the diy way lol ps. the pumps sniper suggested will work great to i just think the in tank pumps run cooler last longer if street driven

wow good catch where was that , i see it now lol. well every thing i said will work with his specked combo on e85 im thinking 700 rwhp + - some depending on combo and set up @ 15psi . that being said hp is only a twist away with the controller lol. i would go with -10 -6 fuel lines and a dedicated race e85 pump for any thing around and over 800 rwhp and have room to grow injectors would be around ID1600s in that 700-800 power range , 2000s after that . 800rwhp + on e85 i would call a sponsor and have them put together a dedicated e85 kit pay now or pay way more later. thanks gezz

The concept of two fuel pumps is getting to me, would i run them in series or in parallel?
I decided that i'm going to use a -8 an line cause i picked up a sump for my og fuel tank and that's what the outlet is, lol
i'm more of a diy type of guy, i just need some assistance sometimes. i would beat my self if i bought a kit or something pre-assembled already.

i was in the same dilemma a few weeks ago but after giving it much thought, i'd rather skip the idea of multiple pumps because that just gives more points of possible failure. 2 relays that can go bad, 2 pumps that can go bad, etc..
i'm going with a big single so that if it does fail on me, i'll just lose complete fuel pressure and the car will shut off.. not like a dual pumper that if one fails you'll go lean and POP goes the cradle.
magnafuel's 4303 pump is a great street pump that is more than up to the task of making high hp (1000+ is common) and its continuous duty so you can drive it on the street as long as you want with no need for expensive fuel pump controllers.
i'm going with a Weldon 2025a pump with the -12 inlet and -10 out and spending the money once and (hopefully) not need to buy another fuel pump again in my lifetime. The 2025 pump is also a good candidate for a street pump but is a bit pricey.
FWIW: i'm building a 5.3 w/ a t6 s475 1.10 a/r in an S10 looking to make 600-700whp on e85 for now and 1000whp in the distant future.

youd run them parallel next to each other and Y them off into a single line to the rails.

best of luck with whichever pump you choose.

have you seen this in the tank pump? and its only $99.99 from SDPC one of the sponsors on here.. The AEM High Flow In-Tank Fuel Pump (PN 50-1000) flows 320 lph (84 gph) at 43 PSI and is capable of supporting over 1,000 HP at 43 PSI.*

I ended up going with a Holley 1400 deliminator pump and a 10 gallon fuel cell.
I stayed away from the A1000 cause i read a bunch of those horror stories, that's the last thing i need. It like a 1 hour drive to the track in bumper to bumper traffic.
I saw a couple in tank fuel pumps but i would have to run dual pumps. I changed my build to a 6.0 with ls3 top end, and tu2 cam
