Hi rallyvan, I decided to put EFI on one of my Toranas a couple of years ago. After lots of reading, asking questions and research I eventually went with the Holley system. Not sure what engine you are running or if its stock or not, but I went for EFI for three reasons.

1) Better cold starts. Engine used to foul plugs if I didn't get it right.
2) Ease of driving at low engine speeds. ( my wife can drive it now) 513hp 383 Chev
3) Complete control over ignition timing and better fuel tuning.


I went for the Holley HP EFI system. which can control throttle body injection, multipoint, sequential, boost, water injection, nitrous or just about any combination you can think of. You can use the system to control throttle body injection and keep it simple, or you can with the click of a tab in the software control cooling fans, A/C cut out, add a knock sensor, RPM spark or fuel cut, timing control and the list goes on. The Holly Terminator system uses the same software as I am using but uses the 4160 style carby look alike. I reckon the Snipper system looks shocking and doesn't look like a conventional carby but is a fair bit cheaper if that's what you want.

The system was very easy to install and is self tuning. I have done over 4,000 km without any problems. I can now lean in through the window, turn the key and it starts first pop every time and idles very well for a performance engine and never stalls. The availability of a knock sensor is great for when I haven't used the car for a few months and the fuel isn't fresh anymore which can very quickly lead to pinging or worse detonation. I have played around a bit with fuel and timing to see if there was any further gains, but in reality the default standard self tuning was almost perfect. I was never warried about fuel economy as performance was my kick but yes I defently have better fuel consumption and a tonne more driveability in every driving situation. And one last thing, I connect my note book up to the Holly computer and through the software can monitor all the engine parameters in real time and can use the datalogger for when I get home and check every parameter and every stab of the throttle, fuel pressure etc.
