912E engines were 2.0 914 engines with L-jet fitted to them. Intresting point that someone brought up was the fact that the engine was fitted with a carb cam....at first thought, I was like huh?

but it kinda makes sense....the whole reason that carb cams couldnt work with D-jet was because the vaccuum signals at idle weren't what the mps wanted or was looking for...so the idle was rough to say the least (a pure guess).

So, in L-jet you have this intresting change....an air flow meter, designed to match the amount of air entering the plenum with the "correct" amount of gasoline, which is running a tad rich--due to the displacement difference. But it doesnt matter how choppy the vac signal is, as long as the engine draws in air, the AFM will know and will give the air some fuel to mix.....


so my Question: could a carb cam be used in a L-jet system for a little extra pep?

1.7L 72 engine.


It's late, so if im way off, just lemme know.
