Default Question on injector size.

I have a lsvtec and im curious to know what injectors would be enough to support e85 and around 500hp.

B16 head:
P&p
skunk 2 pro 1 cams
flat top valves
skunk2 springs and retainers

Block
eagle rods
je 10:1 pistons
81.5mm bore

Turbo
Sc61 with upgrade compressor

I had a stock b20 with a tiny .48ar turbo with dsm injectors and it worked for pumped gas.
But i have never done and turbo build to this size before.

Thanks

1000's will basically be the bare minimum, and limit you to right around the low 500's. Jumping up to an ID 1300 and a larger fuel pump would be the way I would go. Either a DW301, somebody's 340, or the Big Walbro, any of those pumps will get you to 500. Need to upgrade your pump wiring in the process.

And it's always better to have more injector than you need. rather have too much and not need it than to have not enough and need more.

1000s would be the lowest I'd go, 1300 or larger would give you a bit of wiggle room on the power levels

Depending on your fuel pump setup, Fuel Injector Clinic 1100cc injectors for the B-Series could be a nice solution.

When these are run around 50-55 psi of base fuel pressure they will support around 500 whp.
If you run a Walbro 450 in-tank pump it should be a good match for this setup as long as you're not running super high boost (up over 35 psi or thereabouts).
