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?

Sorry Cap'n ... my spec sheet says all are low impedance (2.5 ohms) as I remember. Just another case of mis-information as I don't know the voltage of each.
Regardless, the 912E and Bus injectors are low cc/min also. I would assume that the ECU lengthens the pulse width to accomodate proper fuel delivery for the size of engine. |

This is correct, electrically they should be pretty close but flow is way different. I was under the impression that L-jet adapted pretty well to displacement changes so I am not sure why you want to switch them, even if you were going for big power I would think the l-jet intake would limit you just as much as the injectors would. L-jet injectors are still available new and the locking connector is a lot nicer then d-jet stuff, I would chose the l-jet injectors for pretty much all custom applications. The 2.0 injectors are huge for a type 4. On a properly setup system you would maybe be at 50% duty cycle max. Even on a fully programmable system the only thing you would get is an idle that is harder to tune. |
