Hello everyone! I picked up a turbo for my SBF 347 stroker setup on a 1989 LX Foxbody. It's a single 76/74mm (I believe) Precision Turbo, 2x. 45mm Turbosmart wastegates & 1x. 50mm Turbosmart BoV.
I have a built motor with a standalone tunable ecu but its lacking a fuel system. It currently has the stock fuel rails, unknown/older regulator, stock fuel lines and TrickFlow 44lb (Non E85) injectors.
> My plans are to run E85 and I'd Like to upgrade my fuel system to be able to reliably hold 700HP on E85. (but also open to running regular gas) Planning on starting out with 7-8lbs of boost.
My question is WHAT is the best or recommended combo or components I'd all need to get to where I wanna be. (ex. Fuel pump, regulator, injectors, rails, etc) preferably with Part#'s
I don't want the cheapest thing possible but I'd prefer it not be the absolute most expensive thing. and yes, I know it wont be a cheat date. What is everyone else running or recommend for that?

On a stock block, with a 2-bolt main or is just the fuel system getting the 700HP treatment?

8AN feel line, 6AN return line, Aeroquip fuel pressure regulator, aftermarket injector rails, and 80 lb/hr injectors (used a calculator with 700 crank hp, boosted, and on e85). So with 80 lb/hr injectors (or whatever size you use) you will need a fuel pump that can feel them.

80 lb/hr x 8 (number of injectors) = 640 lb/hr
640 lb/hr divided by the weight of e85 (7 lb/gal - I found it to be anywhere from 6.5 to 7.5 online) = 91.5 gph or 416 lph

So it looks like a 450 lph pump would work but if you noodle around you will see most 450 lph in tank pump manufacturers will say a 450 lph pump will only support 550 crank hp with e85. I would so a lot of research here and see if you need to go external like this one:

A1000 In-Line Fuel Pump

This is the pump that started it all. Durable, reliable, good looking and it supports high horsepower. Perfect for the daily driver that doesn't run like a daily driver.Fuel Injected Engines: GASup to 1300 HP - naturally aspiratedup to 1000 HP - forced air inductionCarbureted Engines: GASup to...

You may have to go larger on the fuel lines so you will need to look at that as well.

Just the fuel system. It's far from stock. It's a fully built 347 stroker. DART SHP block, forged internals, engine management system. Just need help with finding the right fuel system for turbo/boost potentially on E85. Should be ROUGHLY 600+rwhp. Would like wiggle room for HP ratings

Thank you this is very helpful. And yes I have larger braided fuel line. And this pump would actually work good. External is no problem for me.

When my car was turbo'd on e85,I ran a 525 hellcat pump on an Aeromotive hanger, 95# ID injectors with 8an feed and 6an return lines with BBRC rails. FYI, the BBRC rails do NOT clear the dizz,even though they claim they do.
