Ls1 Iroc Swapping to Turbo - billet 78/75 and A/W
#21
I slready own them, friend made 750/850 whp/tq with these exact injectors on e85 in a full size Chevy pickup with the same turbo I have. They will get me to my goal of 650. Then when I want more I'll have them ported. Spending 4x what I paid for the car on injectors is not happening.
Doing a similar build goal of 600ish with E85.

ive maxed out that same 7875 turbo with 80 lb injectors on e85
-6 feed and return
twin 340 pumps
ive used 80s on 3 seperate builds and theyve all made over 700 tire on corn with room to spare
you dont need a giant fuel system for what youre wanting to do.

Yessir, 2.25 tube. I built the one for my nova and it came out very nice.
Thank you, that is the same thing I read all over. Glad to see some more input. The billet 78/75 I don't believe has been released, I'm expecting delivery late this week/next from my pre order. According to vs racing, it's shown about 18% improvement over the cast 78/75. Very excited to try it.

80# injectors on e85 will go pretty fast . my buddy's Camaro ran 9.44@ 140 mph @3550 lbs
20.3 psi boost
15 degrees timing
e85 58 psi base fuel pressure.
80# deka injectors 99% dc.
single on3 78/75 .96 turbo
sbe 5.3 triple 12 cam 706 heads , truck intake/tb.
the 78/75 and 80# injectors are a good match on e85.

Looks good! I've started the same thing but it's the opposite. Just started pulling the 150k 5.3 apart and going to rip it out of the car. Got a custom cam motion cam that just came in and lots of other goodies showing up. Money money money! Great to see another 3rd gen on this forum!
