I recently acquired a car that was originally a 2L and have been told the engine size has been changed to 2.1, which I have not checked yet? The engine currently has webers. Can I use stock d-jet FI if it is 2.1?

If you're after a cheap option to try, you can increase the fuel pressure to the injectors by adjusting the pressure regulator. Probably best to install a pressure gage in there to what you're doing. Remember that flow rate is proportional to the square root of pressure to your injectors, thus is you want 10% more flow you need to increase pressure by 1.1 squared, or 21%.
Since you're only increasing displacement by 5%, in theory you'll only need 10.25% pressure increase. Not sure just how much a stock pump is capable of putting out however, no experience there. |
