I know this is probably a stupid question but can you up the size in fuel injectors and high volume fuel rail kit on a NA motor???? Trying to put out all NA power, figured im going to be putting out more spark and air volume with the mods im going to be putting on my car

current mods:
motordyne tdx shockwave
injen intake
cosworth intake manifold

ordered or ordering:
hks twin dli II
okada plasma coil packs
ground wire system
fast intensions hfc (3in. custom)
3.9 central 20 gears

 

I see no reason to upgrade the injectors if you are staying NA. I don't know what the stock injectors are good for but willing to bet they can handle NA power. Looking at your mods you are not going to need any more fuel. If and when you get tuned your tuner can see how the injectors are doing and if they are close to maxing out...but if they are I would be suprised.
