And I just switched TO FI. (IMG:style_emoticons/default/laugh.gif)

that got me thinking ...
do you still have the carb-cam in it?
or did you go back to stock cam? i'm sure you replaced the old fuelpump with a FI fuel pump, right?

just checking (IMG:style_emoticons/default/cool.gif)

A related question:


Is there any way to tell, by external inspection, which cam is installed in an engine? Or is it necessary to remove and compare it to a known one?

The engine wouldn't run without the D-jet trigger points in the dizzy, so he must be OK there.

i suppose, if you knew the numbers, you could measure lift and duration at the rockers ...

First off, rip off the injection and clean up the engine bay...LOL

I hate EFI!!! LOL

Don't hate EFI. You can hate the D-Jet - the D-jet is very hard to debug because it's all analog - and the only real way to test it's input is to measure all the voltages.

Carbs are in the same boat - you don't really have any idea how much fuel is being delivered apart from subjective tuning.

A decent modern EFI system will output all this information on a computer screen and allow you to tweak all the pertanent values, and thats better than both the D-jet and Carbs.

The D-Jet does run very well for a stock setup though - it was pretty slick technology 30 years ago and I'm suprised that so many cars are still running with it.

As long as we're on the subject. . . anyone have anything to say about L-Jet? I'm eyeballing a 73 1.8 with L-Jet. Owner says it runs good. I guess I'll have to wait until I get a chance to inspect the vehicle (in a couple of weeks) but any opinons on L-Jet, in general?

first thing that comes to mind:
how hard is it to get replacement part if something breaks ???

the PO converted my 1.8 to D-Jet (1.7) and it runs great ...

The statement, as made, is correct. You are misinterpreting it.

The only years that the 1.8 was available in a 914 were 1974 and 1975.

You have obviously interpreted "Charles" statement to mean "in 74 and 75, the only motor that was available was the 1.8". Which does not appear to be what he meant.

I swapped out my D-Jet on my euro-spec 2.0 (higher compression than stock) for the L-Jet, the car ran great, no issues.

Since I did not have to smog the car, I machined some plastic plugs to fit into the air intake elbow to clean up the look of the compartment and to help rule out chances of vacuum leaks.

What other components share that fuse?

Did the wire get hot that you "rigged" to the pump?

What you can do is rig the pump to go directly to the battery (with an inline fuse !!!!) Put a new fuse in the holder for the pump and see what happens.....the car will run and you have removed the pump from the equation.

dont know, Dad had to re route the wiring for the fuel pump when we where working on the pump because it was not getting juice no matter what we did.. he wired it from the relay to turn on when the key was on.

I have a late model 2.0 FI, what are you talking about with closing up the vacume ports? I dont quite understand what your talking about..

Thanks
