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 |

Last week I picked up a triad muffler from Bill in Mt Airy.
Over the weekend I blasted it clear of old paint and what little rust it had. I also got a free, used O2 bung from a fellow teener this weekend at ECC. Today I cut in the opening for the O2 sensor. I cleaned up the used bung and welded it into pace. I could not find a 18mm fine bolt, so I tried to be very careful not to warp the bung while welding it into place. Then I put the first coating of grill paint on it.

The second and third coats of paint will come ay a later date. The first was put on quickly today to keep it from rusting up since I had blasted the metal bare yesterday. Zach |
