So, some of you know, I have always built carbed setups with nitrous. Every time I want to do a turbo setup, it just kills me trying to gather all the parts I want. I have had the turbo, IC, waste gate and boost controller. Sold all of it to build another car.

The thing that always stops me seems to be the fuel system.

What is the best options for the fuel side of EFI with boost?

Fuel pump
Injectors
Regulator

These things I have always ended up finding cost too much to go through with the build.

The walbro pumps seem hit and miss with failures. I myself did a stock 5.3 EFI swap and had the walbro brand new fail.

So, application would be 10 PSI or so and then be able to lean on it pretty hard later.


May do this for my 94 GT that is getting an aluminum 5.3. Will be carbed for a little while, but I think a 07+ truck intake with E85 injectors may be a good option for a little bit.

Walbro 450, Deka 80s, and any regulator (including stock rail mounted).
Solid combo for 99% of street builds.

Don't get a knockoff Walbro....

What Joe said,
Only difference is I went with Bosch 044 "non-knockoffs", Fuel lab FPR, Deka 80's. I also went with fuel rails, but have been told the stock rails will go pretty far for you.

From what I have read the 044 pumps flow better than Walbro's for higher hp numbers. I am like you though, this is my first turbo build. I'm a carbed NA and Nitrous guy. So it is a little overwhelming at first. Just stick with it and get it done this time.

I was always wanting to use the A1000 pump, but that's 400$ off the top.

Wondering if the 3/8 run of the mill factory lines will keep up ok or not.

I'll see what the prices are for the Bosch 044s are compared to a 450 walbro.

Just want to stick with cost effective. I don't mind spending 6-700$ on a BW S480 or so, and I hear the cheap waste gates and blow off valves seem to work well. Just not sure what to do for boost controller yet either.

JoeNova

A1000 is overpriced junk.
Walbro 450 outflows the Bosch 044 at lower pressures but is internal vs external.
3/8 line will support more power than you'll make.
I run a $20 ebay manual boost controller. Don't overthink it.

Or just run it off the gate spring until you can afford a controller. You can buy a genuine Walbro 450 pump for like 120$ shipped.

Don't over think it! A Walbro and stock line will go well into the 600 whp range. I made 651 whp on 1/4 line and a single walbro 400.

I'm going to run a 044, I like them because that are a stock part for some vehicles and most autoparts stores can get them quick in a pinch if yours happens to fail. You can get some injectors for fairly a good price. Check out injector nation. I know the guys that owns the company and you can't get better service then what he offers. And he pretty much beats everyone's prices. IN900'S are the way to go.

Well, so far this little thread is rolling well with great info.

So, the question for some of us, what in line fuel pumps are available for a reasonable price? I want to run external pump on some cars. The mustang maybe not since the tank comes out easy, but when building a 82-2002 F body, I find accessing a external mounted pump to be the way to go since dropping the tank sucks ***.

Stay away from the A1000. Been there, done that. They need to run wide open al the time. So if your not running a lot of hp that needs the pressure and or flow, you end up running a ton of fuel back in the return line so the pump capacity is really wasted. They can overheat and die, mine did. Its more of a drag race pump. They don't like to run and live on street cars.

For the price I am avoiding it. Lol

Of course the S and S pumps I use for the carbed setups works fantastic.

JoeNova

IN900s are $250 more than Deka 80s.

On my gto i used twin racetronix 340s
They come with a billet y block and bracket holding them together for less than 250 bucks
Aermotive regulator
Hardline to -an adapters to use my stock rails and stock feed as a return.
Ran a new feed from a bulkhead in the bucket to the regulator
Siemens 80lb injectors

Supported over 750 hp on e85

Nice, that will support more on gas then I'm sure.

How did you wire them ? I'm thinking of using this pump for my whipple build, dual relay harness and 1 on a Hobbs

Used the factory fuel pump wire to activate a new relay and hotwire from the battery
2nd pump was on a hobbs switch

redss82

the aem 380lph pumps are nice like a higher flowing 044 for a 150 bucks

Was going to say, a member on FB in the sloppy group posted the 50-1005 AEM. That is what I am interested in price wise. 150$ for 380 LPH. One said it should support 750 on E85, so on gasoline it should support 850-900 I think.

I can tell you from experience an aem 380 will support 15# boost on e85 ,on an lq4 with deka 80s. -8 feed and -6 to the engine using stock reg and return style stock fuel rail.

just swapped to an aem 380 on my nova when a went e85. my old 044 worked well to ran mid 10s on 10# boost on pumpgas. both will make power and are cheap. I consider these pumps as good or better than the base a1000. iv seen to many a1000s fail.

I have been running the bosch 044 copy for over three years now and its from here in the states. I believe its made in Texas. PEFP is the company. And i paid less than 100 bucks. So far on stock truck rails and 13 psi on the dyno the car made 535hp with deka 80s on 60% dc.
