I am looking for a few pictures of a L-jet setup.

I would prefer 75 or later and detailed showing the mounting point of the AAR and the decel valve mounting.

I'm in the process of putting my engine back together and I did take several pictures but apparently not detailed enough in the right areas.

thanks

Couple of them...

AAR:

The three prong grounding piece should be under the plenum in order for all the cables to hook up correctly.

The decel valve:

Nope. Notice the double relay on the battery tray. (IMG:style_emoticons/default/tongue.gif)

The big UFO, circular one may have been mounted on the air injection valve bracket which was attached to the 3-4 cylinder intake runners.

Yup, it's either a 2.0 manifold or a 912E manifold. But the AAR shown is the same type that was used on the L-jet 1.8s. The Decel Valve shown is the type used on the D-jet cars (1.7, 2.0) and also on the very early L-jet cars.

The later pics do show a 1.8 manifold.

Having zinc plated a bunch of the hard parts I had a tough time figuring out which arts went were but they are coming together.

I completely forgot that the decel valve was mounted to the engine, I looked in the bay and sure enough its still stuck to the wall.

Here are a few shots for reference, the first shot shows the thermotime switch. The second and third are the auxillary air regulator.

A bit more progress.

The engine is fully assembled less the airbox and AFM. Hopefully when all plugged in the wiring will look a little less messy.

I'm really looking forward to driving again.

I have a few different pairs of intake manifolds laying around. The 2.0L are easy to identify, not sure about 1.7L & 1.8L.

Anyone have the part #s handy?(IMG:style_emoticons/default/confused24.gif)

The 1.7 and 1.8 intake runner pipes are the same length, but the 1.8 tubes have a larger diameter. The 2.0 pipes have the larger diameter but are shorter because the plenum is wider.

Check the tubes where the intake pipes hook up to the plenum.

For part numbers, you can go to the Porsche website and (under Porsche Classic) find a PDF of the factory parts catalog. That lists part numbers for just about everything.

(IMG:style_emoticons/default/agree.gif) My '75 had a little plastic elbow, and then the unobtainable braided 22mm hose. I am currently running my original hose, but I would love to find some new. I bought some rubber 3/4" hose, but I can't bring myself to put in on for aesthetic reasons.

I did just that, and it looks mighty shitty! (IMG:style_emoticons/default/stromberg.gif)
