1.8L vs 2.0L fuel injectors Options

[Geezer914]

I am planning to rebuild my 1.8L to a 2056L using the stock L jet fuel injection. Can you replace the 1.8 injectors with the 2.0 injectors? Would there be an avantage in performance?

Well, I guess I can scrap that idea! Thanks for the replys

No need to scrap it. It will work just fine and its been done before.
L-jet is much more friendly than D-Jet.
The issue with the injectors is simple:
1. L-jet injects 2 times in a cycle and D-jet injects just once for a short period. For this reason D-jet injectors have about twice the flow of equivalent L-jet.
2. Wire connectors are a bit different.
3. resistance is the same. All the talk about the resistor pack is not relevant as both L-jet and D-jet have resistors in series to the injectors but D-jet has them internally.
4. If you want a 2L or 2056cc L-jet, just get a bit bigger injectors or pump-up the fuel pressure to compensate the difference in volume. I gave you a list of injectors that you can use for reference. This is required since L-jet has a fixed injection cycle after ~4K RPM, regardless of the AFM reading. This cycle assumes a certain air volume (1.8L) that in your case became bigger.
5. You'l need to touch a bit the AFM as well to calibrate the dynamic ratio. All the calibrations should be done after the engine is up and running and there are tons of info on how to do it right.
Is that simple.

My advice, if you want to go this route, is to put the 100% stock L-jet on and go from there. Always remember that FI does not add HP.

I would't even consider trying this without a good wide band O2 meter and a head temp meter.
