What parts can i swap from older or newer integra's to my Civic?

 

Like what? If you're asking about every little part you best do a search before you get flamed.

 

I mean like headers, intake manifold, etc. Minor bolt on parts.

 

IF you have the d16y8 motor, then you're intake manifold doesn't need to be changed. As for a header, I would suggest getting an aftermarket AEM header. The throttle body would bolt up. If it's a non abs car I think you can get the rear brakes off it... also rear sway bar.

But I don't really know what a DX is, I'm just assuming it's like my EX but I don't know...
