I am retrofitting this thread to be my full on conversion thread, documenting my change from dual 40 Webers to MSII fuel injection.
Here is what I have so far, and what I need: HAVE:
Built on 1.7 heads. Jake's 9530 cam (carb cam similar to Web 494) Mallory optical ignition ACCEL (UltraCoil) coil. SSI exchangers for exhaust. My goals for this project are to have near stock intake noise volume, better cold starting - especially in cooler weather, negate the bad effects or Ethanol on carbs, teach myself something about fuel injection. Since I already have a pretty good ignition system, I am not going to go after crank fired ignition at this time, but I am not ruling that out for the future. Before I begin the conversion, I am going to pull the engine and do a little refreshing and cleaning, including:
QUOTE I am getting ready to start my conversion form carbs to EFI. My goal is to use as much stock EQ as I can, but replace the sensors and such with modern, easy and cheaper to find stuff. Plus, since my car has a cam, the stock FI will not work. My engine has 1.7 4 bolt heads. 1) are the 1.7 and 1.8 intake runners the same? 2) Is the intake runner inside diameter smaller then the 2.0 intake runner ID? 3) is the throttle body for the 1.8 smaller then the throttle body for the 2.0? If the 1.8 TB is smaller then the 2.0, can the 2.0 TB be swapped in? Are 1.8 injectors high or low impedance? I am asking this as I will be able to get Joe's discarded 1.8 bits when he pulls his engine and starts going down the 2056 route. Zach |

If I have the loaner motor, I won't need it.
If I dont have it, my car won't be driving at Hershey. Kinda like taking an umbrella on a cloudy day to ensure it does not rain. At this point, if there is someone that needs the motor, I can't justify having it on hand for insurance. Especially if you are going to ship it cause you are not coming this weekend. |

Well, I will keep it on hand for you until you know for sure. They are in no hurry for it as they are Volvo guys. He was just going to design a ms system for us d-jet guys as a favor to me. I have it on hand in my storage unti on an engine stand in plug n play condition. Something happens and you need it, I will strap it to a pallet and send it right away. |
