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 |

I've got a nice fuel pump you can have if you decide you need it. It came with my car which the previous owner had converted to ITB fuel injection. However, when I bought the car it had no engine, so I built a six with Webers. I'm using a Holley low pressure pump.
The extra pump is a Bosch 0 580 254 979 which is rated at 165 liters/hour and maintains pressure at 5 bars (72 psi). It came stock on 78-79 930's and 79-82 924 Turbos. The pump was probably used for about 500 to 1000 miles of driving. Anyhow, the pump looks like this: (IMG:http://www.914world.com/bbs2/uploads_offsite/i954.photobucket.com-11663-1318475865.1.jpg) This is a stock image, though. Mine has -AN fittings on the intake and exhaust ports, plus a mounting bracket. They cost quite a bit new but I really don't need it and I have noticed you contribute quite a bit to this site's content. So if you want it just pay for postage (probably $10.) and it is yours. Let me know. Rob |
