I am thinking of putting my fuel injection back on my '74 914 2.0. It currently has webers on it and I have the motor out on the stand. Will it help my resale value if I put the injection back on? The case is non number matching.

Depends if you have a carb cam. Not compatible with the FI.

If the cam wasn't changed then yes, more valuable with a good working stock FI.

Uh, yeah.

Reminds me of a joke my kids are telling right now...

"Road Work Ahead?"

"Yeah, I sure hope it does..."

It will drive smoother with better fuel efficiency. No gas smell either. Worth more, probably but it is a pain to track all the parts down and get everything working if your only goal is to get more at the sale.

My daughter and her friends wouldn't leave that one alone about 2 years ago (IMG:style_emoticons/default/smile.gif)

It will start on first crank, run smoothey when cold, and just be more responsive (IMG:style_emoticons/default/piratenanner.gif)

It will also run better up at your altitude than with carbs & without re-jetting whenever you go down to Bishop or lower altitudes, but the cam is the question as noted above.

My 73 2L with EFI always ran flawlessly down here in the LA/OC lowlands, & whenever I went up to Mammoth or other mountain resorts to ski back in the day when she was my DD.

Just got done last fall with refurbishing a 40 year old '74 2.0, kept the original D-Jet. Took a great deal to get it right, however, the car was ICE cold yesterday, had not been started in 5 months and started on the first turn.......very cool!

D-Jet is a very elegant example of Analog 'computers' which, for the period were state of the art and pretty much indestructible. Worth the investment in knowledge IMHO.

If you have the injection parts or access to them at a reasonable cost, put them back on. Since your engine is out, now would be the time. Much easier and increased value.

Agree with everyone about FI but don't overlook the important point above. If there is a carb cam in the engine, the decision is already made for you unless you want to split the case to replace it. And if you do, you'll be faced with the "while I'm there" syndrome. That's the boat I'm in.

Cam is key consideration from what I've learned.

If FI came now is the time - I'm going to do the same on one of the 2.0l I have.

Yeah but splitting the case and getting in there isn't that big a deal. Jeez, they are souped up bus engines.

Not for smooth transitions of power.

Cams have a particular profile relative to its use, FI cam lobes are shaped differently than a carb cam.

Carbs rely on vacuum to meter out fuel, while FI relys on vacuum the deliver air while a computer decides the fuel mixture.

The difference in what is being delivered and how determine shape of the lobe.
