This system uses a ballast resistor, here is a pic of the parts I used when converting my '74 164E to this system:
The dizzy is from a US spec '75 164E with B30F.
ECU is from an early 264 with B27E.
Coil, resistor, and wiring harness are from a 240 with B23E.
I can supply the coil/resistor/harness if you're looking for those parts, possible an ECU also. The dizzy's were US market only and very hard to come by.
As for the injection, I have a lot of D-Jet B30E parts available, ECU's, injectors, sensors, wiring etc, however it can be hard to get the system to run right. The MAP sensor on the RH inner guard is a weak link in the system, the diaphragms in them often fail or people try to adjust them, finding one that works properly can be hard.
The contacts on the TPS and on the timing points in the base of the dizzy can also become dirty and cause problems.
I originally planned to convert my project 164 to Megasquirt, and bought a kit which I never assembled, the car remains unfinished but at this stage I'm leaning towards running it on straight LPG instead, with an Impco 200 clean air mixer, as it's simple, easy to tune and reliable.
The D-Jet system is pretty cool from a historical point of view, being one of the first EFI systems, from memory the ECU doesn't even use any microprocessors, just lots of transistors, but it's not easy to keep it running well at this point in time.
As for cleaning the injectors, anybody who cleans EFI injectors will be able to do it, the machines consist of a small ultrasonic cleaning bath, with a rack that the injectors sit in so that the tips are just below the surface of the liquid, and wiring plugs for each injector.
The machine slowly pulses the injectors while they're in the bath. The solvent used is a lot more serious than kero, it strips the paint off the bodies of painted injectors, so reco injectors usually have a fresh coat of paint.
The machines normally also have a series of test tubes where they can be run at full duty cycle and the flow rate measured, and spray pattern observed.
You might be better off to give them a pile of injectors, and tell them to test them all and mark the best six for you.
