My car has a 2056cc engine in it, but with the stock L-Jet fuel injection. And when I was modifying the engine I went ahead and put in a slightly more radical cam. I was wondering if I shoulf keep the L-jet and try to "tweak" it to privide enough fuel, or if I should switch over to Webbers?

BTW, does anyone out there have information on the diferences between the fuel injectors on the 1.8L vs. the 2.0L (mainly flow rates).

What modifications did you do to the L-Jet (if any) in order to get proper mixture on a 2.0L?

Nothing.

The extra air pulled by the 2.0 made the AFM flap open farther. That made the mixture correct for the 2.0.


I ran 3% CO and the car ran great!

do you have anyway to compare performance of a stock 2.0 D-jet and a stocke 2.0 w/L-jet? or any comments on the comparison?
