yea
Almost all parts will interchange as they have the same chassis and series of motor.
There 's none.
yes they are the same transmission, does not matter if the engine is a d15 1.5 liter or a d16 1.6 liter
If its a 89 Honda CRX si wih manual transmission, use genuine Honda MTF. You can purchase it at any Honda or Acura dealer near you.
All 1984-1991 crxs that haven't had motor &/or trans swaps have cable transmissions. Only swapped ef crxs depending on the swap, have hydrolic transmissions.

No not the bumpers.

== == Honda didn't make a CR-V in 1991, so I'll assume it's a typo and you meant a 1991 CRX. In any case, it also depends on whether it's automatic or manual transmission. Regardless of whether it's a CR-V or CRX, here's the guidelines on fluid recommendations: Manual transmission: Honda Manual Transmission Fluid is preferred. Alternate substitutes are 10W30 or 10W40 motor oil. If you have a CRX, it'll take 1.9 quarts of fluid. If a CRV (1997-2002), you'll need 1.8 quarts. Automatic transmission: Honda ATF-Z1 Automatic Transmission Fluid.. If you have a CRX, it'll take 2.5 quarts. If a CRV (1997-2002), it takes 3.0 quarts.

The trans from a 89 CRX DF should bolt right in to the 91 CRX HF. The only problem is if it is a 1988 transmission, then you would need a different clutch disk and possibly a new pressure plate too. All flywheels, mounts and axels for these years fit all the transmissions for these years. They do not interchange, but they all bolt up to your trany the same. The CRX EF has a special low-reving engine and a special wide ratio transmission to get you 50 MPG. With a higer geared trany, your MPG will drop. No one knows how much. But it will bolt right it.
All CRX Si came with manual transmissions.
