Default fast 85lbs injectors on L92 intake

ill be paypaling Rick today for a turbo kit ( sadly not mine ..)
and I was wondring if these will fit the L92 intake manifold

this is the part number 30857-8 found them on Ebay for 380$

they are 85@58 psi

I dont know if they are the short style or the long ones

he also runs a 255LPH , I dont think it will feed them sufficently past 4.5-5k RPM

Those are the short ls3/7 type. I ran those in my turbo 6.2 with a stock flex fuel pump. Didn't have any problems. You will need the fast spacer adapters to run those on a l92 intake tho but there cheep I think around $40

yes sir... stock rails, stock lines and stock flex fuel pump. Ill have to ask my tuner what my duty cycle was but dont think it was ever a problem even with boost at 8lbs and a stock 6.2. Yeah with my turbo 6.2 setup there was really not much done to the truck. Basicly stock everything besides the addition of a t72 turbo system, meth, and those injectors. Truck ran strong.
