I wanna know what size injectors are ideal for my set up.

I've got a rebuilt bottom end (built last year) with a e303, aluminum svo turbo swirl heads, 1.7 ford Motorsport rockers, explorer intake, 65mm throttle body, mac cold air intake, straight pipe exhaust etc.

I currently have 24lb injectors in the car right now and have a set of 30s with matching maf laying in the garage. Would there be any upside to getting the 30s put in or are the 24s just fine where they are at now?

Okay cool! Do you know what the limit is to the 24s and when 30s would be needed? I plan on doing 3.55 gears next, I've got 3.08s right now. Not sure if the gearing would call for more fuel but I'd say I've got a finished motor as far as all my planned mods go.

24 lb injectors will support 300Hp @ 80% DC and fed with 43 Lbs of fuel pressure.

you can change the gearing all you want, it has no effect to the need for more fuel. If you dont already have one, I would recommend getting an adjustable fuel pressure regulator, preferably Aeromotive brand [patriot]

wow, I was always told Aeromotive was one of the best and BBK was junk lol. I've been running my Aeromotive for about 7 years now, no issues.

They're all roughly the same price so if one starts acting up on me I'll get my money back and get the other
