Exactly right!downest said:For the MPFI swap you need a MPFI intake manifold, ECU, injectors, distributor, resistor box, and a soldering iron.
I have an HF and a DX. I'm looking at swaping the FI's around to keep the DX but have MPFI. If this just a simple swap everything over or is there specific parts I'll need from other models?2point2 said:Exactly right!downest said:For the MPFI swap you need a MPFI intake manifold, ECU, injectors, distributor, resistor box, and a soldering iron.
The wiring in the hardest part, it's very intimidating for some people but if you follow the instructions and ask questions you'll be fine.

This is for a ZC, but the only difference is that the Cylinder Position Sensor wires, which are the same colours, are external on a ZC instead of being on the main distributer plug - if you're confused, don't worry.. it will make sense when you do the conversion
This link is a nice reference to the way the pins are laid out, colours and functions.
This link shows you how to remove pins from the ECU plugs. Cut off some ECU plugs at the local auto wreckers leaving plenty of wire. This takes some practice.
Use solder and good quality heat shrink for all connections(the good quality stuff looks dull vs shiny) I like to double up on the heat shrink when two connections rub against eachother. Most importantly, take your time because it will prevent huge headaches down the road.
Good luck, you will learn a lot doing this conversion. :wink:
