Injector size on my new engine
I recently got a new engine for my fox...it started out as a gt-40 crate engine but i modified it to be supercharger friendly. Here is whats done to it. Dart pro 195 heads, forged pistons, stiffer valve springs, 1.7rr, lower end girdle, holley intake, comp cams xfi cam, canton oil pan...not bad for a total of 3300 bucks but anyways i was curious what you guys would recommend running for injectors and maf? The engines going in this winter and is most likely going to be naturally aspirated for a few months b4 i get around to supercharging it so i would like to get injectors and maf that would be big for now but be able to use in the near future with the supercharger. Any help would be great thanks everyone

go 42's get the MAF to match and upgrade fuel pump to a walbro 155lph in tank with an inline 30-70 psi AFR from aeromotive...this way you can adjust as needed, remember you can always tone it down but you can't add beyond max ability of the pump and injectors!

+1 I would just go with a 255 pump, Im not sure about running 42lb/hr injectors on a NA motor though... even if your just waiting for a blower. I have a set of Motorsports 30lb/hr's if your interested

I agree, 42#r's are to big unless your wanting to run over 10psi. 30-36Lb injectors will be much better and one 255LPH pump.
