914-6 Fan Shroud Education, Fitment and availability of upper air guides Options

[DennisV]

We have an original 914-6 engine, sans the fan shroud (aka upper air guide) and tin. Can someone educate me on fitment and availability? Is there a definitive fan shroud article or post? If so, I could not find it.

What I understand is correct would be a 911-106-901-00 Air Guide Upper Black. This appears to be shared with 1969-71 911T with carbs.

What we do have is a red shroud, which appears to be off of a 1977 911 Turbo. It has a couple cracks and some bolt holes broken open. I have no doubt it could be salvaged with some effort, but even then I am wondering if it would fit correctly. There’s a post on the early911sregistry site, which suggests there are differences beside the color but doesn't go into much detail.


It seems like they are hard to come by. I did find one currently on eBay that says it has been “modified”. It this my best current option? Does anyone recognize the modifications?


Of the after market vendors I found mentioned in old threads, it appears that series900 may still be selling them. I am waiting to hear back from them. Does anyone have first hand experience with the quality and fit of their product compared to original?

Thank you.

blk one on Ebay is a year too early,,, but could work if you had the grey oil cooler duct wich the 914-6 Has.
Should look like this, But Blk .

jeff,

doesn't your yellow example have the injector cut outs?

I don't know crap about the right one for a -6
but assumed it was probably not an injector cut out version.

they do show up from time to time on pelican for sale in the classifieds...
I haven't looked lately.. but bought a few over the years from there.

That would be consistent with the Early 911S 2.4T MFI photo caption.

That's a good suggestion. I see one was up a few months ago, but without the grey oil cooler duct. Is that something that can be added on, or do you need to find one with it already attached?

I have a black on on my car currently. Wanted to go to amber at some point

I think I see what you mean by this now. According the parts catalogs, 911-106-406-00 Air Guide for Oil Cooler was on:
* All 914-6
* 1972-89 911

Are we talking about the same thing? It looks like that part can still be bought from Porsche. Is it retrofittable to the older style main shroud?

The subtle distinctions on the 914-6 combined with 911 could drive a person mad!

[sixnotfour]

yes yellow has mech injector holes ,,reason i didnt mention it ,,There is no blk with injector holes, and the Red 930 shroud has wrong shape intake also.. CIS

[sixnotfour]

* 1972-89 911

The short shroud, islate 72-89,
You need the long grey one..as my picture.

you could buy the blk early version find a green or yellow shroud that has the long grey oil cooler shroud and add it to the blk one

Check out the two photos. The first is the shroud that would be correct for your 914-6, from my car. It should have the long grey oil cooler feed riveted on, no injector cut outs and black in color:



Mine has been subject to fire damage from a previous life and a "racers" repair executed to get it functional. Another one I have is from a later air cooled 911, showing the "shorter" grey snout on the oil cooler feed, and a large section of the duct now molded into the main "bump":



This is not correct if you're looking for originality.

Also note that there should be a curious inner cowl that fits around the alternator with some air directing vanes that help cool the LHS cylinder bank. Hopefully you have this already, if not it is worth sourcing one for even cooling to all cylinders.

PS. Either of the above could be for sale, if needs be....

the second shroud is a 74 non S shroud , pretty rare ,,but where as doesnt have injector circles it has CIS port Configuration

Damon made me a brand new one that i am very pleased with fit wise. He also understands the variations year to year with the different ducting. He even can fabricate the inner ducting that helps divert air to the cylinders for proper cooling. He takes a minute to respond but is worth it. It will not be cheap

I went to look in the parts stash

I think 2 early? And 2 later

The amber is on the racecar

the last red one of the Groupe can e modified to accept the Grey oil cooler duct....Holly Molly You have alot of red fan shrouds..

I am fairly certain that the 914/6 fan shroud was the same as the 911T from 1970-71. I made a factory tour in 1971 and saw a 914/6 engine on the assembly line in the middle of all the 911 engines and there was no reason for a different shroud. The 914/6 I drove from 1970 until 1973 had a black shroud.
The early 911 engines had the long gray runner to the oil cooler. There was an improvement in the early 1970's with a removable piece to allow access to the oil cooler bolts without removing the shroud. I don't remember exactly when this happened.

Thanks everyone for the info.

Has anyone done a retrofit of the grey piece to a black shroud that didn't come with it?

Another one I have is from a later air cooled 911, showing the "shorter" grey snout on the oil cooler feed, and a large section of the duct now molded into the main "bump":

I think I finally get it with the side-by-side photos. I wish Porsche made a distinction. In the PDF parts catalogs, it appears to me that they list the same 911-106-406-00 part number for all 914-6 and also the 1972-89 911. Clearly not the same!

Is this what I'm looking for? Photo courtesy eBay.

This is very cool! I think there should be a whole post detailing this experience.

I purchased a early shroud (carb holes). It was pretty bad shape, fiber glassed broken areas, then did a gel-coat over sanded glass and painted red for my 2.2 E with S pistons. Then added duck to oil cooler. Best, Mark

Same as a 911 2.2T carbureted
