I am very close to starting on my 6 conversion.

I have a decent inventory of parts now. Many of the parts are from my '77/'78 911SC hybrid donor car. I've seen that many folks ditch the CIS for carbs, but I would like to keep the CIS if I can.

I've heard about CIS interference issues requiring latch relocation and using banjo fuel lines to clear the trunk side of the engine bay. Are there any adjustments to mount locations needed to make the motor fit without cutting the car? What other surprises may I be in for?

Some of the parts I am using are RJ bulkhead mount, a WEVO 915, DW oil tank, and MSDS headers. Parts I still need are engine tins, oil lines(hoping to mod the 911 lines), and chassis reinforcement. Parts recommendations welcome.

Thanks

Rich calls for an installed height of 7" on his mount. It is possible that you may be able to lower it to 6.5" so the fuel distributor will clear. Give him a call and see what he thinks. It's what I'm going to do on my next one.

I also cut the trunk torsion bars out and used the shock kit.

I just cut the engine latch off and used hood pins on each side. Racing bling ya know.

You do know that if you want to use a 914 transmission you have to acquire a '70-'71 901/911 transmission** or have Kennedy make you a flywheel out of a type 4 or early 901 flywheel. 6 bolt thru the 2.7L and yours is 9 bolt. That's why I stay with the 2.7L even though I do have a 3.0L. Maybe there is another way of doing it, but I ain't that smart or have enough money.

** Clutch kit for this transmission is $800.

You will have to install the front engine tin after you have the engine installed. It won't clear the mount when installing the engine.

Well, that's my experience anyway.

Step away from the J Gumby

Thanks for the tips. You have CIS in yours? Any pics?

As for trans... I just finished going through the trouble/expense of modifying the 915 with a WEVO side shift kit and a Guards Club 40/60 LSD.

Yeh, Scotty nailed me on the tranny .... guess I don't read with comphrension.

I sold the first conversion and do not have images of it.

The second conversion is on the back burner so I don't have any images.

I used CIS on both cars.

Wish I could help you.

The modified 915 should bolt right up to your 3.0 liter, that's what it mated with originally in the 911, so no problems there. You'll like the 915 gearbox, it shifts nicely as long as you don't try to speed shift too often. Changing to the rear trunk strut kit will gain you a bit of room at the back of the engine compartment, and makes for a nice, clean install (actually a whole lot nicer than the torsion springs). It should be possible to relocate the engine hood latch, but the hood pin idea is not a bad one.

When it's all in, you should have a nice setup. You might also check with George Hussey (Dr914 @ Auto Atlanta) as I believe he has this same setup in one of his cars.

Is the 915 superior enough to a side shifter to warrant the expense ? I have both and have debated whether or not to use the 915 in the 914 or hold on to it until if and when I get an early 911 to build

For me yes. For others maybe not. My 901 needed a rebuild and I wasn't interested in spending anything on it. I really didn't want to live with the shortcomings of the 901 anymore.

You can flip the whole CIS system and have the airbox on the firewall side, I have seen it done, but you need to modify the engine shroud.

Also you will need a 6pin CDI or an MSD setup.

Cool! I was wondering about that. I'd like to have seen that.
I have an MSD.

the problems i ran into with my 3.0 install was the cis was to tall
so i dropped the engine mount by about one inch including the tranny.(on Eric Shea's recomendations)
deleting the breather hole on the back of the rubber boot attop the intake
and against the wishes of the purists and the paranoid i cut a hole in the fire wall for timing and belt replacement
and you will need to cut the engine lid latch off. relocate it if you choose to keep it
with dropping the engine the shift rod will need to be modified, and the rj engine mount will need to be ground a bit for clearance( on the engine side)
skip the idea of trying to turn the intake around...if you want to go to that length
you should just do carbs.
there are plenty of cis converted cars with the cis in its stock location

OK
First...you wont get an early 911 to build...face it.
Second...BEETLE...dont waste it on a 914....seriously
Its as tempermental (if not more so ) than a 901.

Rich

Says you, I know of 2 that are mine if I want them BEETLE ?? Nah I've got a bus tranny in my baja

Hole in head!!!!
Find me an oval already....or at least a split roof clip...
Rich

Yes that's why I haven't gotten either one. I have other projects I'd much rather do

Zactly...

Now, hunt me down a split window roof clip.....please...
Just the back window and vents...

Rich

With some minor resurfacing, you can use the 3.0 flywheel with the 901, you will need a new starter ring , clutch, pressure plate and throw out bearing(I got my parts from Kennedy). The 901 is easily up to the task with a 180hp 3.0.

I had to shave the ribs on the rubber intake boot with mine and notch the back edge of the engine lid around the fuel distributor. I relocated the latch but later pinned it.
I have the stock 6 mount, if i was mounting a new mount i would place it 3/4 to an inch lower to accomidate the engine height, and space down the tranny a little too.

I haven't tried it yet, but I would think that you could rotate the fuel distributor to clear the fuel inlet lines from the rear firewall. Since it is constant injection, the position of the feeds shouldn't be important as to cylinder number.

Just a thought.

I'm installing a 3.0 with CSI soon. I've collected a few pics of what others have done....may help:

Audi airbox used in the first 3

some more:

The Audi airbox pics are my old engine, It was a 2.7 and was first in my white six, before I pulled it for a 3.2 upgrade.

I sold it to Doug? and those are pics from in his car, It was a slick set up and seemed easy enough to duplicate. I think it was the airbox from a 5cyc audi IIRC with the fuel dizzy mounted on. You can see the pop off valve and the epoxy to seal the top of the runners.

Yellow one with the shaved ribs is Mountain Man's yellow six here in CO. Not sure what engine mount he has.

Ferg

Here is a pic out of the car, before it went into the orange car.

goose...that orange 914 with the modified airbox has it even run
i rember seeing those pics two to three years back....

I think he had it running and then sold the car. Not 100% on that, but I remember it being for sale shortly after he got it together.

Ran great for me. I drove it to CA and back twice, most reliable 914 I have ever had.

Ferg

....not my car, just pictures I collected in anticipation of my install. But I do have a project car in progress...or lack of progress. I started it a couple years ago but got busy moving, building new house and shop and boat stuff. I plan on getting back to it next summer. The car had a 2.4 (Rootwerks car), I built a fresh 3.0 for it....got all the good stuff to make it work...but no time . Stay tuned...I'll surprise you all one day when I drive it to a meet.

If you do a search here you can find pics of my 2.7 CIS. I cant find them on this computer. It is not hard to do

This thread has gotten interesting!

Ferg - That is a really cool setup. Are the throttlebody and intake runners mated to a modified (trimmed down) 911 airbox?

Goose2 - Thanks for posting all the pics. What do you know about the motor with the green shroud?

Also the 3.0 CIS has an AAR valve and another valve that stick way off the back of the system (flywheel side).

My 75 2.7 CIS fit fine in my car with no trunk latch, but it looked like those two valves on the 3.0 CIS wouldn't fit in their original location.

But my 75 2.7 was extremely reliable, had it running for 8 years with no problems...and it still runs I just upgraded to a 3.0.

Patrick Motorsports mount IIRC - can't find the part number though. Makes the 3.0L sit perfectly with the CIS.

Nana's_914, What did you end up doing with your 3.0L Injection??

I am about to attempt this and was leaning tward flipping the injection?

I would love to hear your results!
