As stated in earlier thread:

2.0 case, 96mm Je pistons, AA cylinders, "fat" performance cam 413 lift,258 duration, Melling oil pump, 009 distributor with Mallory electronic sensor.

CIS: VW Golf/Rabbit GTI Air/fuel meter box,Porsche 911 fuel accumulator,Bosch VW
warmup regulator(WUR), Bosch cold start valve, VW bus plenum and throttle body.
Injectors(#?), Fram fuel filters (one pre pump,one pre fuel meter), Bosch Fuel pump from Mercedes 300 series(as I was told,prob. good for any CIS auto from the 80's).

Thanks to Dave Toppin good friend(through all this) and mechanically inclined!

Thanks to Steve Limbert who inspected case and crank.

Thanks to Bill Boys(Possum Hollow Motorsports) who sorted out some bugs with the CIS.

The CIS is based on a design by Gary Miller and Ed Viella.
PS the flares are steel. Cheers,Dion

Can you provide more details , as in the fuel sump / pump setup ?? Any list of sourced part numbers ?? Another fella posted recently about converting to the CIS / K Jetronic setup , no feedback yet. How about performance , fuel economy ( especially sought after in these fuel times ) drivability , idle ,off idle capqabilitiess .
I for one am very interested , others maybe also . Please more pics and descriptions.

Thanks ....

Jack

Hey Jack,

The basic kit came from Gary Miller, I got it second hand from a friend about 4yrs ago before finally being installed recently.
Here is what I have:
Improved driveability over the tired Djet. You can feel the increased response. The torque is there. It idles smooth at 900 to 1000rpm. Fuel eco? Put it this way, even with spirited driving I don't visit the pumps too often. It sounds nice and throaty too,not quite as nice as a six... It is not sluggish.
I hope to get hold of a gtech for what it is worth,but will have it dyno'd.
On paper with the mods were expecting 120HP-130? at the flywheel.
Parts: Fuel pumpBosch #69430,WUR #0438-140-011,Inj. #0437-502-015,Fram filter
G371,Rabbit airduct 067-133-357and 067133373, Airequip and other Co.'s Fuel lines need to be rated for 250psi working rate. The meter is from G1 or G2 VW. Pick up a Bosch Management book for details on the CIS setups it proved very valuable.
Hope this helps a little.
Cheers Dion

Will add more pix soon...

=271055]CIS PIX

very interesting, I managed to keep a CIS setup from a GTI I parted out years ago. somethign to keep in mind.

Nice job!!! Have not seen one of those CO adjusting plugs in a long time.

Thanks Dion for the fast reply. Yes I have the book , been reading the heck out of it lately .Read from the STF about some of the VW guys using this conversion with good reports , also checked out websites related to this mod, Gary's seems to be unavailable for info, just haven't contacted the sand people. The engine I plan on using came with dual 40 IDF's , will rebuild them and use first , when the engine goes in , but am planning on sourcing this setup . The only parts that I have for OEM FI is a set of intake runners , no other parts . The sourcing of this setup would probably be a little less $$$ and easier at this point , no ECU stuff to debug . Thanks again , glad to see someone else posting this conversion and doing the pioneering for some of us .

Thanks...

Jack

Not one picture shows the injectors and how they're installed. Pix, please?

The Cap'n

Very pretty set up and clean engine bay.

Nice setup! I currently have CIS on my stock 1.8L but plan on using it on my 2056 motor that I'm in the process of building. Please keep us updated if you get it dynoed. I too would be interested in seeing how the injectors are mounted.

Cheers,Dion

Nice and clean looking , personly I'd fab some sort of injector holder . I wouldn't want a high presure fuel squirter coming out because of a hiccup or backfire. Were they originaly secured in the donor vehicle ?? Thanks for the pics , blurry or not , gives an idea of how the setup is accomplished.

Jack

Hey Jack,

Good idea regarding securing injectors. I'm not sure how inj. were secured in the VW's. But as far as coming out... It took a decent amount of oomph to pop em' in.
Thanks again for lookin' in.

Cheers,Dion

Nice work and nice write up. Thanks for sharing this.

No , Thank you for sharing the conversion pics and part numbers. the reason I asked about the secured injectors is that all the other conversions that I found online used some sort of injector clamp. The orings are to stop any vaccum leaks, but the injectors are high presure squiters not a lot different from D-Jet ,L- Jet and other presurized fuel injection and they have secured injectors .
Please post more when you can , also like I said before curious about your fuel sump / pump setup - location.
Great looking engine and 914 you have there , keep it going !!

Jack

Stock CIS injectors are just held in by the O-rings, but they are *in there*. Takes a heck of a lot of effort to pull them out, even with dry, cracked O-rings that leak air all day.

Really clean setup. It's somewhat tempting to me, since I've been futzing with CIS since buying a VW Fox 22 years ago (I still own and mod it). Any particular reason for going CIS versus a standalone system like Megasquirt? Note that "Just because" is an acceptable reason to me.

Click to view attachmentClick to view attachmentClick to view attachmentJack here is the fuel pump pix. The pump in front trunk secured to wheel well. Fuel lines entering under tank. One filter secured under steering rack. You can see in the one pic peering out from panel. There is no movemnet near this bellows so it became an easy spot to secure it. Did not want too much equipment in the spare well. I have yet to make a little"cage" to put around the pump. My bud Dave is a fabricator, he has some ideas and access to some cool metal materials.

Kerensky: I'm cheap. This was an economical? build. So to speak. The CIS seemed to be well proven on factory cars. Not to mention another bud of mine John I. has a turbo'd CIS car. His car has ran well. All these parts can be had at NAPA or a FLAPS,
and salvage yards. I wasn't building a race or "killer" car just a dependable nice driver. Thanks for the info on the Injector securing.

Cheers,Dion

The intent of a standard injector clamp is to keep the fuel line on the injector. The high fuel pressure would blow off the line otherwise. But on the CIS injectors, the line is threaded into the injector, so the clamp isn't needed.

The injector tip needs to be sealed into the plenum to prevent air leaks, but remember that on a normally-aspirated car, the plenum pressure will always be less than atmospheric, thus the car is always trying to suck the injector into the engine.

To sum up -- you're OK without injector clamps on a CIS injector.

Thanks Dion. So essentialy you're not using two fuel pumps to get fuel from the tank to the distributor. Most of the OEM Rabbit setups have a pump in the tank to pump to a sump , then the main pump draws on the sump to send presurized fuel to the front engine compartment to a fuel filter / distributor , if I am correct in comprehending the system . Thanks for the pics , so others say that the injector clamp isn't needed. Ok .

Jack

Good and helpful info DS -- also explains why there's no reason to over-tighten the 10mm retention nuts.

Thanks for the great pictures and description of your project, Dion, super-interesting!

The CIS system Dion installed is from my project when I was building the clone of Evil ED's turbo no need for injector clamps even with 12 lbs of boost!

Just for the record I didn't buy"John's project". Some major components came from the kit John initially bought from Gary Miller. Other parts were needed to tailor it for my car.Just sayin' John.

Just for the record The CIS kit that Dion installed was the entire kit as supplied to me from Gary Miller which included ; the intake runners and injectors, plenum, fuel pump, trottle body, fuel distributor with injectors and fuel injector lines, fuel filter, trottle plate boot and hose, custom mounting plate to mount the fuel distributor( to the engine fire wall). Not included in the kit from Gary; was the bosch fuel acculator ( but part # was supplied) and some additional high pressure blue fuel line needed. Just sayin' Dion

I kinda like the wheels.

Good Taste Elliot. Thanks.

John,Sorry I thought I gave credit where credit was due.You purchased the kit from Gary,then you sold it to Dave,then I purchased the parts. Some of the components had to be replaced because of non function. I was making the point that these parts can be bought with relative ease without going through Porsche and the ever increasing price of d jet parts. CIS works nice on these motors.

Cheers,Dion

If someone was interested in one of these kits, where would they go? Gary Miller is sort of a common name to google.
Never mind, found him pretty quick. Is he still making kits? His website is in disrepair.

Zach

Nice work! I love that CIS system. Definitely a good FI.

Jake installed a CIS system in one of his transporters a few years ago that was lifted straight out of a Rabbit or Golf. I can't remember if it was a K-Jet or a KE-Jet. It ran great and looked like it was meant to be there.

Zach,

Gary kinda disappeared, we tried calling for info when initially installing. No luck.
If you look at the components,you can find them in salvage,Napa,FLAPS and get a Bosch book. It takes some tinkering.
I don't know of anyone making a kit now for "retail"

Cheers,Dion

No problem, and cheap is an acceptable motive - I use it a lot!

Ok thanks for the pictures Dion. I have been looking for FI alternatives since rebuilding my D-jet earlier this year. I have found that the boards are starting to go after many years of heat cycling....I live in California...and am looking for future alternatives. I don't like carbs.

Several things if you don't mind:

1. How well does it run...Hot starts? Cold starts? Tinker factor with AF ratio's ect.

2. If there is cost benefit....then how much do you figure over D-jet? I know that D-jet parts are getting scarce. What did you pay for the parts..if you don't mind saying.

3. Is this a KE or a K-Jetronic.

4. Do you have any Dyno numbers ?

Thanks in Advance

Whoops....

Sorry should have read the earlier posts....

Very interested in the hot starts though where I live......

Thanks,

Rob

Who makes those wheels? Haven't seen a lot of 4-lug options. Link please.

Hey Rob,

During the toasty days we had in PA in late July 95*F It ran well.
It needed a little coaxing on restarts wth the gas pedal. I'd let the pump run a couple of seconds to push the fuel through.,push the gas pedal down,crank till it fired. It would start in few seconds. No issues.

The set up not counting the 2.0 rebuild with the bigger P&C's,was around $700.

The CO2 level is around 4.8 - 5.8 according to a gas sniffer.

I'd like to get it dyno'd by end of summer. I'll post.

Cheers,Dion

The wheels are by Revolution. UK based they did have a rep in AZ. I don't know if they are still in business here. I did see the UK site was still up. Mostly Rally wheels now.

this opens up a great option , such as running a euro dist,
but what does the big dog think
Jake...comeon chime in

Just saw the thread. Fantastic job Dion.
Very clean and proffesional.
I guess now you can kick some turbo butt.
lol lol

Just saw this thread after all these years. Really cool upgrade from the original early 70's D-jet FI system.

Could this CIS system be dialed-in for a 1.9L built up from a 1.7L? I have the 1.7L heads with the 4-bolt intake runners and the stock 1.7L air plenum

If I remember correctly, CIS is based on airflow, so I don't see why it wouldn't work. An air door pushes up on a plunger that adjusts fuel delivery. I think the only adjustment was idle CO.

@euro911 Mark I don’t see why it wouldn’t work.
I’ve sold that engine and induction on to jmitro.

He’s in the process of firing it up ... after 3 yrs.
Waiting on further word of how he’s doing.

I always thought the induction on Dion's engine had a "factory" look to it. I know it wasn't stock but looked like it should have been.

Too bad Jim/Type47 isn't around. He build a couple of these engines.

Here's a video of Jim and his engine. https://youtu.be/z-owfyoayUg

Nice one Mark, good stuff!
