If they are not the skinny pencil style injectors, but the fatter SVO injectors, you will need to trim around the topside of the injector port to get them to fit right

you shouldn't have to, i have the pencil style injectors on mine and they fit no problem. from what i have seen with the fatter injectors you have to trim the top edge around the injector boss where the upper shell meets the lower to get them to fit correctly

Do not trim the intake, you need o-ring adaptors, I have has to buy them. Call fuel injector connection (FCI) and they will hook you up

Id buy injectors that are actually designed to work with the intake. Not modify the intake to fit injectors it wasnt designed to be used with.

From who? I would call FAST and ask....


Mine looks just like that, and CPG said I can use my stock LS1 injectors as long as I use their O-rings...

Who did you talk to? Its an FI system...Fuel is sprayed into the runner, not the valve. There are tons of people not running the pencil tip LS2/LS3 injectors with this intake w/no issues.
