Are there any diiferences between si and non-si del sol (non ABS) brake boosters or are they the same?

Is the 91 Civic ex sedan brake booster directly compatible?

Also just to confirm, as long as its a non ABS 92-95 96-00 civic ex si or 94-00 non ABS integra, it should be able fit?

 

You can use an online OEM parts site to confirm part numbers. Try Acura Parts | OEM Acura Parts | Factory Acura Parts

Integra and Civic brake boosters are different. You need the brake master cylinder for the respective booster. In other words, you can't use a Civic BMC on an Integra brake booster.
