Fuel Injection Options and Advice Options

[bkrantz]

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?

Going aftermarket really opens up your choices as far as cam selection and head work which will make a huge difference in how your engine performs. Aftermarket will also allow much more accurate fuel and timing control which will also affect how your car performs. Add to that the fact that all d-jet is 50+ years old now and pretty much all new parts are NLA, including some parts that are absolutely necessary for the system to run and the fact that even when new d-jet had its shortcomings/limitations.

Dont get me wrong, d-jet is a fine system for what it is. 3 of the 4 914s I currently own are d-jet cars at the moment but my car with a built 2056 and Megasquirt is just a night and day different experience from a driving perspective, especially when you have built a motor to take advantage of it.

I think it really should depend on what you are looking for. If you are going for concourse/originality or don't want to spend the time and money to go aftermarket, stick with the d-jet setup you have but those are the only reasons i would consider sticking with d-jet at this point (and sticking with d-jet may wind up being a false economy in the long run anyways)

Im currently recovering a numbers matching 74 LE bumblebee, its getting the last of my stash of 2.0 d-jet parts but its been a fight getting it running correctly and I spend the whole time wishing I could just let myself put Megasquirt on it (but i wont due to originality purposes) The rest of my d-jet cars will eventually be getting Megasquirt, just not at the moment as they are currently running fine.
