88-91 Prelude Si fuel injectors into 91 CRX Si

I am waitin on a pair of 88-91 Prelude Si fuel injectors. Now, I know they fit in the CRX Si 91. My car does run rich already which can be a sign of worn injectors, but besides that, my friend said that'll I'll have to get a new fuel pump and something to make more air like a bigger intake manifold. This is what I have done to the car so far:

Exhaust/DC Header
Rebuilt Head
Short-Ram Intake
Spark Plugs/Wires
Next Level Performance Chip
Hollowed out cat. converter

So do you think if I were to put these Prelude Si injectors that something will get screwed up? Their brand new by the way.

Stock fuel pump is good for 200whp at least so it should be fine.

Getting more air will mean that the computer puts in more fuel. What you need is to get something to tune w/ lika a AFC.

...aren't those injectors the same flow-rate as stock si injectors?

could be, I guess I was assuming they were bigger

...pretty much all honda injectors flow at 240cc... if you want some higher flowing injectors.. I believe the 92-96 vtec preludes had 345cc peak/hold injectors...and later models had 280cc saturation injectors.. of course....I think these are just gonna make matters worse unless you've got a AFC..
