What are the size of a 99 civic ex Fuel injectors?

 

240cc

 

what is the best size to run n/a and what style? (saturated and peak hold)

 

240cc injectors running at a recommended maximum of 80% duty cycle can support 38 Hp each. Multiply that by 4 and you get a 152Hp max for your stock injectors. The thing is though, you will need to either adjust fuel pressure or the injector pulses to accomodate the need for added fuel.

Saturated are a little more durable but peak and hold will deliver your fuel a few milliseconds faster. I would suggest sticking with the style that you have in your car now.

 

what style is in the car is what we are trying to figure out?

 

Saturated (high impedence), 240's

 

will 310's be tomuch for n/a engine?

 

probably. unless you have a pretty radical build, 240s will be fine.

 

is there an upgrade 240 injectors, and where can I find them?

 

what about stock b16's...what size are the injectors in those?
