K-Jetronic installatio/mods

Hi,

I am about to try to fit a K-Jet from a 2.0L Peugeot 505, into a 1.5L 305 motor. A couple of questions/thoughts;

  1. I think I can get most of the stuff to fit, but wonder as what effect shortening of the intake runners would have?

  1. Would the air flow sensor be okay here, or would I have to find one from a smaller, ~1.5 L motor. AFAIU, it is the profile of the air sensor "hood" that is basically the "engine" map. They both have similar bore/stroke ratio, 1.04, 1.07

  2. I also figure that I could lean out the fuel distributor to brink the mixture closer to the requirements of this smaller engine.

I've also installed a lambda sensor to have some kind of indication of af ratio.

I would appreciate any input or ideas...

regards,

Yes- make the inlet manifold volume too small and you'll get the airflow meter plate bouncing at each inlet stroke and have all sorts of problems!! You need a 'buffer' volume of air to stop this. Don't ask me how to calculate the volume though...

The fuel map is basically controlled by the shape of the 'funnel' that the airflow plate sits in. I can foresee you're going to have more problems at low speed / small throttle openings where the plate is going to be open only a small amount getting the fuelling right.

Worth a try!

Make sure it doesnt run excessively lean!
