Are the 92-95 Civic Si injectors the same size as the 94-up GSR's? I've been hearing conflicting info regarding this. A few peeps have said that they are the exact same thing, while others say they are not? Who can settle this once and for all for me?

 

Someone answer this - I want to know too.

 

Yes, they both use 240cc injectors, the difference is that the Integra uses a bigger fuel pump and a different regulator set at a higher fuel pressure level. Your main resistriction on the civic is the pump and regulator.
