Cheapest cost effective fuel system
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.
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.
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.
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.

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 ***.
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

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.
