Siemens FI114510. Direct fit LS2, USCAR/EV6, 48mm length and 53.5lb/hr @ 43.5psi and 62.0lb/hr @ 58psi.

Was told they are a "stock SRT4 injector with no data for the ls1 box" by someone. Looking to verify. Wondering if anyone has these and if they got tuning info with them or if they are running good or what not.

NOT looking to run spacers, adapters, or resized/redrilled injectors. Trying to find a tunable LS2 drop in injector in the 60# range if possible.

Thanks for your help

Main problem i've found with those style injectors from OHC engines, they use a wide spray pattern, the port walls get wetted with fuel.

FIC should be able to get you injectors the right spray pattern.

Either that or use FAST LS2 injectors, direct fit.

The FASTs have intriqued me and I would go with the 57s although I've heard NO data is provided with them. No calibration sheets...etc.

Dont know how they sell any of them without it, but its enough to keep me from buying until I get the facts which is VERY hard to find on direct fit LS2 stuff. Its like Im the first person trying it (I know Im not, but jack **** comes up in searches everywhere).

Thanks.

Have you checked with RC Engineering?

I'm positive the FAST injectors are modified factory LS2, they flow 57lbs/hr @ 58psi.

Roughly i'd guess them to be 48lbs/hr @ 43.5psi
