I finally got to drive my 914 again! (IMG:style_emoticons/default/mueba.gif) (IMG:style_emoticons/default/biggrin.gif) Back in June I was having fits with the L-Jet system that was on my car so I decided it was time to tackle a project I was wanting to do for some time, a CIS conversion.

I retrofitted a CIS Basic system to my stock 1.8L engine using parts from various VWs and Mercedes and today I fired it up for the first time and was able to take it for a long drive. It felt AWESOME. Smooth reliable power all the way to redline. It has a nice growl to it too. (IMG:style_emoticons/default/evilgrin.gif) I'm quite impressed. I still have to make some small adjustments but at least now I can get back to driving the car daily and the best part, NO MORE JACKSTANDS! I'm going to drive the snot out of the car this week to get the system dialed in and hopefully next weekend I will take it for a day drive in the mountains. (IMG:style_emoticons/default/driving.gif) More details and pics to come later.


The cat is happy too!

(IMG:style_emoticons/default/popcorn[1].gif) I always thought CIS off a VW Rabbit would work nicely. Post lots of details! (IMG:style_emoticons/default/first.gif)

Great idea and congratulations. I'll bet a lot of folks will be interested in hearing about what you did.

CIS works great on TIV engines.. I had the set up on my Grey shop Bus 10 years ago along with a stroked TIV.. The torque was phenomenal and so was the MPG.. The simplicity of the system is what I appreciated most.

I didn't touch it for 7 solid years.

CIS? Would that be "Cat In Situ"?

you guys are nuts...I don't let the cats on my cars because they scratch the sh$t out of the paint!

Easy to train them. Just wait till they're settled in on the hood and fire it up!

I am working on the same thing except from what Rick suggested, from a Rabbit. Actually, Someone else is working on it (already installed one on his son's Teener) to teach me how to do it. I absolutlely love what he did.

You should see the top on my 1973 911 targa, they love that soft top for sleeping and clawing.

Okay here is a break down of everything I used.

Fuel distributor – VW Rabbit
Warm up Regulator- VW Rabbit
Fuel lines-Audi
Fuel Injectors-Audi
Fuel Pump, Filter, and Accumulator – Mercedes 300 class
And assorted flexible hoses and fittings from various German cars

I used stuff that was readily available at the local junkyard and I spent less than $150 putting this system together. The easiest route though would have been to just get everything off a VW rabbit and be done with it but the junkyard didn't have a complete Rabbit at the time.

The pictures show my initial installation of everything. I’ll clean up some of my workings now that I know the system works to my liking. The airbox/ fuel distributor is simply bolted to the intake runners, the warm up regulator is mounted to the firewall, and the Mercedes fuel pump assembly is mounted on the firewall under the engine.

For the injectors I had to fab up some brackets and spacers so that they sit at the correct depth.

And finally since I was completely new to anything CIS, this book was a great reference!

One of these Volvo 240 Aluminum Air Box Tray's would probably fit in there a little better than the Plastic box.

Yeah I need to do something about that. I had to remove the rain tray just so it would fit. I was thinking about fabbing up a new box. I'll have to look into the Volvo tray though.

I was drooling over Dan & Jeff Dixon's CIS setup on Dan's Type IV at WCR and asked for detailed info. Jeff sent me this great site Ferrari400parts.com. The is a lot of documentation there.

Volvo 1800s also used this system and I've found some info by searching for it.

This is definitely something that is in my future since I've got my own 914, my son's 914 and my other son's VW Bus to think about. It certainly looks superior to anything VW/Porsche ever put on a Type IV!

Are there particular years of Rabbits that you want to find for this?

Thanks for all the photos!
