Good morning and happy Saturday.

I bought a low mile rebuilt 2.0l engine that has carbs but also came with a full FI set up up that supposed worked fine before someone got an overdose of testosterone and felt the urge to tweak the fuel system (prior owners description (IMG:style_emoticons/default/evilgrin.gif) ).

Anyone put FI back on a car? Seems fairly straight forward but....

Check to see if the cam is FI. Carb cams different animal and will not run well with D-Jet.

(IMG:style_emoticons/default/agree.gif) +1 The cam is often changed when engines are converted to carbs. It's the only reason I've put restoring my original FI on the back burner.

Oh, well that is a good consideration.

I have no idea.

Changing the flat 4 cam is a lot of work. You will need to pull the engine out and remove everything necessary to be able to SPLIT THE ENGINE CASE OPEN to get to where you can pull the cam out to replace it. You'll also need to replace the fuel pump to get the correct pressure for FI.

Enjoy the car with carbs for now and put off the cam change.

Even worse would be IF the original cam for FI was never changed when the FI was removed.

Is there anyway to tell, short of disaseembky, what cam is in it?

It was an FI engine that was rebuilt with FI on it before it was switched (based on what I was told).

The way the '73 1.7 yellow FI car instantly starts and idles and pulls is compelling.

How much do you trust what you were told?

If it was rebuild and running on the stock FI before the switch to carbs then it still has a FI cam.

Hi Jim. Everything seems to check out from what I was told prior to purchase and then what I saw when I went in person to pick it up.

Worst case, I suppose, is that I would put the carbs back on it.

What happens when an FI system meets a carb cam? Earth spin backwards? Dog and Cats start sleeping together? Or just bad timing/fuel ratios?

Thanks!
