riggs 74

Which size and price on a set of injectors for an LS2 NA 500 to 550 HP
at the fly wheel.
Mods well be, Cam, headers and a retinue, plus port and polish if things go well.

I wasn't sure if I could actually go too big, or could I leave room to grow with out any
ill affects on performance.

Thanks in advance.

What are the part #s for 60lbs injectors? I have data for one type only..

I'm interested in something in the 60-65 lb-hr range for a H/C LS7. What would you recommend? How much?

I'd also like to use the stock LS7 injectors on my 5.3L Truck; do you have adapters for that? If so, how much?

Thanks in advance.

The FAST 65's would work great for you, they're $370. Please give us a call about the truck fitment.

Question regarding injectors:

After my cam-only setup, I'm currently at 84% duty cycle(at WOT) per my scans and am debating the switch to E85 in the relatively near future.

Is there any downside to going with a big injector NOW in preparation for the E85 in the future?

Can the tune be adjusted to 'downsize' the injectors until more fuel is needed?

My apologies if this question is elementary, but I figured I'd ask.

Thanks in advance

Car details are in sig if they're needed

You should be fine as long as you don't go too large. You can't change the amount of fuel they flow in the tune.

I have a C5Z with a built motor and YSi. Im upping the boost alittle 17-18lbs(flip drive) and sold my 80lbs injectors just incase I need more. I currently run a LS3 intake. What injectors would you recommend? I will be buying them within the next couple weeks. Also if you have a recommendation on fuel rails. Ones that are good but hopefully cheaper in price.

THANKS...
