1976 914 2.0, MPC D Jetronic fuel injection California car. Questions:
To add the center three gauge console. Car has the, DPD AC. Does the console have to be cut down to clear the AC duct? Is there a special upper bracket to mount console to instrument panel. Is there a bracket to console to tunnel?
Will non Porsche VDO gauges work with Porsche sending units? Like oil temperature, oil pressure? There is wire harness that can be bought for adding a gauge console, is the wiring already under the instrument panel?
DPD AC; Is there a bracket available to mount a Sanden AC compressor instead of the old two cylinder York or Techumseh compressor? The front, in the nose AC condensor. With a retrofit to, 134 refrigerant, does the AC condenser need to be upgraded to a modern condenser? I assume replace the AC hoses? Is there a kit out there for a compressor mount and condenser replacement?
Where does the distributor vacuum advance hose attach too? Under the throttle body? Is there only a vacuum hose on retard side of the distributor? No hose on the vacuum advance side (front of distributor)?
This will be a good start, thank you in advance, Steve V.

I would say a different gauge will not work properly with the factory senders. I kept the 3 gauge center panel and added oil pressure and oil temp mechanical gauges (1 1/2" diameter) mounted to the tunnel on the passenger side close to the seat.

I cannot comment so far as the AC goes.

Best of luck with your new purchase

I can comment regarding the AC...
I run an Automotive AC specialist shop in N. Texas

No kits available directly for the 914, there is some stuff available for the type4 in other VW vehicles.

Real Sandens are good compressors and not expensive.
95% of the stuff available is Sanden "style" and is not worth installing.
Make sure it's real Sanden.
IF "American" Sanden is available buy that. Sanden does make compressors in China now. I will use a Chinese Sanden if nothing else is available. The price difference is usually $20-$30 more for the American stuff.

I don't use ANY other Chinese compressor at all...

Vintage Air, Old Air Products, and Ranshu are my normal sources for this stuff.

Vintage Air is high level. Their "kits" are the best in the business. Calls to them are answered by a "car guy".

Old Air products. High to mid-level. Lots of reproductions on original stuff. They make their own condensers, and I use them OVER any aftermarket condenser. Their condesnsers kick ass!

Ranshu is "piece together only" but has a HUGE database of stuff they can get. When you want to mix and match these are the guys.
Ranshu can supply "White Box" new compressors. These are FACTORY compressors in a plain white box at 33% cost.
I ALMOST think they are stealing them off of the assembly line...
Excellent source for newer cars.

Need barrier hose.

Upgrade to "reduced barrier" and use steel fittings.

The 914 stock condenser location is poor. It doesn't have enough fan and flow for R134.
It really didn't work great with R12 either.

I was going to try stacked dual condensers and larger fans but have decided to go water-cooled anyway and the radiator mod gives adequate room for a nice sized front mounted condenser.

Another member suggested two condensers, one in the back and the normal one in the front. This idea has merit.

I still do R12 work and if you can find "me" close to you, you are COMPLETELY legal to use R12 in your system. R12 will work better than R134 for a stock condenser location.

I would not re-use the original condenser. Get a modern condenser from Old Air Products. The modern "flat fin" multi-pass condenser has about 60% more heat rejection capabilities than the old "serpentine" style with round tubes the size of pencils. The refrigerant paths through the new condensers are TINY and get the refrigerant very close to the aluminum and that actually works far better.

Q: Does the console have to be cut down to clear the AC duct?
Yes
Q: Is there a special upper bracket to mount console to instrument panel.
Not that Im aware
Q: Is there a bracket to console to tunnel?
No its screwed to the tunnel
Q: Will non Porsche VDO gauges work with Porsche sending units? Like oil temperature, oil pressure?
Umm depends, why not use OE or compatible gauges?
Q: is there a wire harness that can be bought for adding a gauge console, is the wiring already under the instrument panel?
Below the carpeting is a pigtail for connecting its specific harness to the console
Q: Where does the distributor vacuum advance hose attach too? Under the throttle body? Is there only a vacuum hose on retard side of the distributor? No hose on the vacuum advance side (front of distributor)?

The 3 stock gauges are oil temp, volts, and a clock. The stock gauge diameters are bigger than VDO aftermarket (2-3/8" vs 2-1/16). The aftermarket gauges will not read accurately with stock senders.

For oil temp, you can use the aftermarket VDO gauge with the correct sender, screwed into the stock location (in the plate under the engine case). For oil pressure, you need to add a new gauge and sender. And how to plumb the sender is a bit complicated, if you want to keep the idiot warning light, at least so it goes off at the stock pressure cutoff. I am not sure how to add an aftermarket volts gauge.

Obviously, to add oil pressure you can remove the clock or cut another hole.

The vacuum advance doesn’t go anywhere. Its use was discontinued by 76 but Porsche didn’t change the distributor. So they ran a line into the open engine bay. The old port on the throttle body was eliminated. So just connect the retard line.
