    I have three 142s, one D-Jet, one Weber, and one with SU's. My Weber is on a 72 I bought new and converted about 20 years ago. After one kit in the carb it is still works great. 340K total on car. For simplicity I don't think you can beat it. To keep a D-Jet system going you had better have a basic knowledge of electricity/electronics and patience to find problems with an Ohm meter. The 71 with the SU's is the one I have not messed with much. It might be ok, but my understanding it takes a higher level of carberator understanding than a Weber.

    So, I you are in a trading mood I would like to have some spare D-stuff. In return I have a spare Weber set up I bought online but not used and SU's on a daily driver car that I am ready to get rid of.

      I would be most interested in your weber setup. I have a 1974 144GL w/a B20F that I would like to remove the Constant Fuel Injection setup. Is your setup a side draft type? Apparently, the downdraft setups have upper range flow problems.

    I'm looking to convert to D-jet 140-160

    hello,

    i'm looking to convert my 64 122 to fuel injection. How much are you looking to get for the parts. I need to find a manifold/butterfly, throttle position sensor, linkage? I already have D-jet injectors from a 160 6 cyl and the b20f head installed on my bored b18.

    I'm going to build a Megasquirt efi computer to control the system. Check out the link for Megasquirt info:

    I have an extra set of S.U.'s that need a rebuild (pulled from a car in a salvage yard) and can get a cast intake manifolds with the integral exhaust. (i have a separate aluminum intake installed w/S.U.'s, but being my daily driver i can't let it go until i'm done with the conversion.) Maybe your interested in a trade for the S.U.'s and or ?

    Is this a daily driver or project car or both?

    take care,

    You will get a whole host of responses for and against this idea. Mine is against it. D-jet is precise and reliable, and unless the components have failed, is better performing on a stock mechanical specs engine than any carbs.

    Phil S., who might weigh in here, wrote the excellent piece that taught me D-jet.

      ok. I read the article, but I still want to carburate the motor. Don't get me wrong though. The injection system sound very reliable and efficient when working correctly. I have a limited amount of time though, so I just want to get it running. Who knows. I might just leave the system in the car, and tweak and make it work later. Thanks for the showing me the article. It is a keeper.

        The easiest way to do this is just to remove the intake manifold and replace it with a carb manifold. You can actually leave everything else in place, injectors, etc. You will have to replace the fuel pressure regulator with one that will regulate in the 0 - 5 lbs. range. Just remember that the high pressure for the FI system is created by restricting the return line to the tank. Reduce the restriction and the pressure is reduced. If you do this and leave the fuel system wired to the ECU and the ECU to the distributor, the fuel system will work normally. If you remove the ECU, and/or other wires to it relating to the fuel pump, you will have to rewire the pump and relay. If you are going to remove the injectors, there is a freeze plug that will fit and is the easiest way to plug them.
