Excellent site here for Porsche 914!

Did the 914-6, as from the factory, have the tail mount shifter as did the 1970-72 Porsche 914-4 so the shifting is similar to the 1970-72 914-4?

Was dealer-installed AC offered as an option on the Porsche 914-6?

Thanks!

From the factory, the /6 was a tail shifter. I have been told the mechanism at the tail has a different arrangement than the 4s. Maybe I'll look at my friends just for kicks.

A/C I have no idea, but was dealer installed as far as I know.

Oh...welcome to the madhouse....insanity, insults, etc,. abound here. We do have fun though.............

The factory 914-6 had a slightly different version of the tail-shift transmission. The gearing was different, and the external linkage was slightly different.

I don't know offhand of any 914-6es that came from the dealers with AC. It is possible, but I think the AC kits were intended specifically for the four-cylinder cars. I know of one or two that have been converted by their owners, though.

The 914-6 factory linkage has one less articulating joint than the 4 cylinder (just aft of the firewall), so it is a bit better than the 4 cylinder linkage, but still not as nice as the sideshifter in my opinion.

I tried to find any information on 914-6 air conditioning, and from what I've seen, only the Brumos 916 was converted at the dealer. The kits were for the 4 cylinder cars, and the compressor and associated brackets would have to be completely different for the 6 cylinder engine. Even the 916 had a rather cobbled up system as the firewall had to be cut and notched to clear the compressor belt.

It's amazing that no one has come up with an alternative AC system for the 914-6 after all these years.

There are few 914-6 that have A/C systems. Most are DIY custom installations.

It is possible to have the A/C compressor mounted so no sheetmetal is need to be cut.

Mine was fabricated while the engine was out of the car. It would be a PITA to fab up the bracket(s) while in the car.

Cheers

I have the compressor mounted on my six. But I have not finished the AC install.


Hell.. I just got the damn thing back up and running after breaking the clutch at the MUSR......

Thanks everyone for the good info!

Only 2nd and 5th are different between /6's and /4's

a six has a Taller 2nd, and shorter 5th

Kerry or Clay,

Do either of you happen to have a photo of the AC compressor mounted w/o cutting the sheetmetal? I understand that on the Brumos 916 that the firewall had to be "dimpled" to clear the compressor pulley at the top.

Second that, any pictures of a compressor mount on the six engine without cuttting the firewall would be very neat to see. That is really the only change between the 4 and 6 AC install.

Got any pictures of this? The six in the shop looks awefully similar to the other tailshifters I've seen. This is what mine looks like.

The six doesn't use the pivot point to the left of the bushing hole. The shift rod comes out of the tunnel and connects to the rear shift rod with a simple swivel joint. The end of the six shift rod (at the transmission) is different than the four cyl rod too.

Here's a link to my website that has pictures of the custom made AC compressor mount.

Six cylinder AC compressor mount.


It fits in the engine compartment without cutting the tin or the firewall. It also clears the battery tray. Sorry, I don't have pictures of it in the car.

I used clewett engineering v-rib pulleys. This makes the belt easier to change. The belt is a common one that can be bought at any FLAPS.

The idlers are bolted to a bracket which is welded to the motor mount. It could probably be bolted to the motor mount so it would be removable.

The compressor mount hooks to a couple of 8x1.25 nuts that are about 30mm long. This fits the compressor above the valve cover.

After putting this in with the plug wires, I took it back off and put a hole in the bracket. Then I put a straight plug wire end on the wire and ran it through the hole. Now I don't have to pull the mount to change the #1 plug.

Here's one picture of it.

I'll take some photos

The bracket and pulley system are DIY. On mine the only way I could avoid cutting things up was to add a pulley system to push the compressor back from the firewall.

The rest of the A/C can be the same as a type 4 install..BUT mine isn't by choice

Clay has a real nice set up, one of the nicest one out there

His link shows what is needed to move the compressor back. Mine is similar in concept but uses a two V-belts...I was too cheap to get the above pulleys.

When I get ready to remake the mounts, I plan on making one plate that bolts to the front of the compressor ears, and one that bolts to the rear of the compressor. that way it won't have to mash the Heater hose. Plus if I make it out of Aluminum, it should be lighter.

Alum. would be nice but that is just too tough to DIY with my tools

I removed my heat so I didn't have that issue.
