Pearl's rcsb awd turbo build!
#154
i know how you feel - right after college, i broke a rod in the old 4.3. having only temporary on-call work, it took 5 months between saving up the $$ and installing parts to simply get a new engine running in my only vehicle.
it'll come around soon enough!!

Here is what I plan on my fuel system.
e85
160lb bosch injectors
walbro 450 in tank
a1000 on a rear sump
10an feed
8an return
aero boost regulator
Might be a little over kill but it will get me more than i need!

In terms of injector matching, even with those 2 in parallel you are pump limited. 160s are huge injectors compared to the pumps.
at 20psi of boost with a 60psi base pressure (stock)
160s flow 771 l/hr
450+a1000 flow 712 l/hr
Which means you will actually drop fuel pressure above about 12psi of boost. Not really a big deal, because even with the pumps max output at 20psi of boost you have enough fuel for about 1150rwhp on the corn. Your injectors max (at 95% idc) around 1250rwhp on the corn.
The matching looks worse on gas, about 150rwhp difference between injector capacity (1770rwhp) and pump capacity (1620rwhp).
