The 91 (far as I know this is true for 88-91 CRXs aswell, but I know 91 for sure), CRX Si and HF, both have MPFI (4 injectors), not DPFI (2 injectors), and most certainly not carbed... The DX or base has DPFI (2 injectors), no carb here either... Si is def the heaviest, but not by much, and stripped down, they are about the same anyways... The Si & HF, are both easy swap candidates, since they are already wired for MPFI, as this is what you need to do just about any swap... The DX, since its DPFI, would need to be wired to MPFI before any swap... So you should not have problems with your Si and a swap...
