I have a 97 Integra. I want to use 450cc injectors off an eclipse. Can I just exchange the 450cc Injectors with the ones on my car or would I also need the clips from an eclipse?

 

Is 97 obd2? If so, you will either need the clips from the eclipse or obd 1 clips. You will also have to put in resistors or a resistor box for them.
Do a search under the forced induction section and you'll find tons of install info.
