Big fuel injectors

June 14, 2013, 03:33:28 AM

My spec clutch doesnt have many miles left before its broke in and I put my Stinger PIMP ECU in. I want to put 65lbs injectors in but I am not sure which brand to get. Stinger Doesnt sell 65lbs anymore more, so I dont know what to look for to make sure they fit properly even.
Any help would be greatly appreciated! Thank you

I use a lot of FAST injectors in my engines. They work great on my LS builds. Hers is a source for the ones you are looking for. I think the PIMP can support these. If not call STINGER for specks. Hope this helps Thanks

If you're not sure, just buy a set from Stinger, even if they're a bit bigger. The ECU is programmable. The typical issue with larger injectors is trying to get a good idle quality. This was more an issue in the early days of the MS (and other aftermarket ECUs). These days with improved resolution and control, it's not a problem. Get some 80's or 85's and not worry about it. With your mods list, you might be limiting yourself with 65's anyway.

OKay thank you guys for the help. I wasnt sure if injectors 75LBS and up would give me worse gas mileage and just not preform well. Stinger has yet to email me back even.

What is your goal HP number??? If it is 400 you will need eighties. Other wise they might be a tad on the big side if HP is lower but workable to a point. Also what will your FP be. If it is 45 LBS?? Eighties are on the high side but workable at 80% and .6 @45 LBS

Well Id like to run around 21-22 lbs of boost. Ive heard that these motors blow gaskets at around 24-25lbs. So I am not sure what horsepower i'll make with my mods at 22lbs of boost. I am not sure about fuel pressure. However I am looking at the 75lbs injectors from stinger. The stinger PIMP will do most of that tuning and for fine tuning, I am going to take it to a local dyno tuner that specializes in cars with power adders.

Then the tuner should recommend the injectors. That is what you are paying him fore!!
