Default Bigger fuel injectors, how big?

I was thinking in to buying some slightly bigger fuel injectors for my 93 civic. I just want some thing new, that will give me a little better throttle respone. I dont want to go too big, I just want the new injectors to compliment some of the other mods on my engine. What is the size of stock injectors on a 93 civic ex 1.6 in CC's? Also, how big should I go, and what brand?

Thanks!
Andrey

Depends on what you have on the engine.

go with some 97+ prelude injectors. they are 280cc as compared to the stock 240s. its not a lot bigger, but you dont need too much for those mods.

thanks for the reply.

Would the prelude injectors fit right in to the AEM fuel rail for the 93 civic, and would they work with skunk2 intake manifold? In other words, would they just pop in and hook up with out any other mods?

Thanks a lot!

im 95% sure they will. i know the mitsu injectors people use a lot, need a little bit of modification, but its nothing major. but yeah, for high compression NA, go with prelude injectors. but they have to be 97+ because you need saturated ones, not peak and hold.

I take it that the stock fuel pump will be able to keep up no problem?

thanks Sacicons!

with the 280s, yeah, no problem, though you will want an adj. fuel pressure regulator to get the full benefit of your mods.
