Decision time soon (preferably only once). Later this month I will pick up my refurbished case, crank, and heads from Competition Engineering in Phoenix. I want to build this up to 2056 and use fuel injection.
So, do I keep the stock D-jet that was on the car? I have no idea if it works. And I expect that I will spend time and money tracking down rebuilt/replacement components. Plus modify the system for the increased displacement. Or do I go aftermarket, spend more time and money, but hope for better results? And maybe some sexy twin intakes? |

I’m planning aftermarket FI my 2056. And I thought I wanted ITBs, but I don’t want to have to sync anything. That's one of my reasons to convert from carbs to FI.
So here’s a question... Is there any reason to think the stock djet runners, plenum, throttle body won’t flow enough air for a 2056? Discuss - I’m riding down the highway through Planet Utah. |

So here’s a question... Is there any reason to think the stock djet runners, plenum, throttle body won’t flow enough air for a 2056? I think you would need a pretty extreme 2056 before it becomes an issue to consider. I dont recall the exact figures but i did the math on it before and I think it doesn't become an issue until you start getting above ~140HP at which point you also need to be thinking about exhaust (headers) as well. Mine is a bit of a screamer (spins to 7k) and im running it through a modified 1.8 l-jet Plenum with 50mm Vanagon TB. I suspect where you are at the stock 2.0 plenum and runners would be preferred from a drivability standpoint as it gives a better vacuum signal, and in theory probably better midrange torque. |
