Basically, it's converting a DX or LX model EF with dual point injection into multi-point injection by using a MPFI intake manfold, Si or HF model distributor, Si ecu, and an injector resistor. There are also some wiring changes to be made to the DPFI wiring harness. Try searching the archives, there is a ton of info in there.
