The Duane Spencer Book 'The Complete Porsche 912 Guide' RPM Books, is great and worth every penny. There is a page of books on the Register site which is quite definative. see www.912register.co.uk
Not sure if Dave Hillman has the procedure for putting a VW engine in a 12 but his site is down at the moment.

I made the motor swap into my '66 912 for a vw type 1. The bored and stroked vw motor is a 2176 cc, Breathing through some dual 45 dellortos, some ported heads, big valves, and a good size cam, this motor rocks. Makes 185 hp at about 6500 rpm. I believe it's a very beneficial conversion if you're willing to put up with all the globs of power that you won't know what to do with. Driving past the 911 6 cylinders is always fun, especially without having all that weight in the back of the car. (the vw motor is even lighter than the 912 motor by 15 lbs, so it handles like no other) The conversion was relatively cheap, the only real mods I had to make was to install a rear engine mount. I used a kit which is for converting last vw buss' to a type 1. Making some tin to keep things cool in the engine compartment wasn't much hassle either. I say go for it!

YEA I WAS THINKING ABOUT THE TYPE 2 REAR SUPPORT BAR. NEVER HEARD OF THIS TYPE2 TO TYPE1 BAR CONVERSION THOUGH? i WILL BE RUNNING A 1641 STAGE1/2 VW BUT IM NOT TOO CONCERNED ABOUT POWER...HONEST. (SO ABOUT THAT 911 LUMP......)

Hello,

I am writing from Montevideo, Uruguay, ( South America )
I own a Porsche 911 S coupe from 1976 but with a lot of problem with its engine. Here is very difficult to obtain spares and a mechanic to fix this type of engines so I am considering to install a Volkswagen Type 1 engine.
I would very much appreciate if some can inform me if this is possible and if so if i can use the 911 s 5 speed transmission.

Your reply will be very much appreciated.
Thanks - Best regards
Guillermo

Hi I hope it is as thats what i am doing. I was told that there is a difference between a 912 gear box and a 911 box where the clutch engages but i cant see it. Let me know what you find out.

Hi: I have a project with a vw engine and temporary placed a mild 1641 vw engine on it. I will eventually have a 1.8 or larger vw engine; is basically a direct bolt on. You must use the newer vw pressure plate without a collar ('71 or newer) and vw clutch disk. Be sure to change the lower case studs for the larger type 4/porsche 912. They are about 1/2 inch or 13mm longer than the type 1 engine. Then you have to make the engine tin yourself. good luck in your project, Jose

THANKS! THE TIN LOOKS LIKE THE MOST FUN!

Steve great site ..I have just made up some tin wear for the Ex's Speedster kit car running a 912 engine It was abit of a head atch at first but once I got started it all worked out OK. I used Ali for the metal and insertion rubbber to seal the edges It looks the biz so I am very pleased with Test run it to day and it looks to be fine.


Made is in 6 separte sections and PK'd them togeather nice and strong. Pot rivited the rubber strip . Painted it with high temp black. I have made the shapes so it covers the fuel pump and the pully just like the org tin wear. I must have closed up the gaps up to 98%ish

I have done it and run it. For certain: A VW Type 1, 1300, 1500, or 1600 does fit into the Porsche 912 chassis. Specificaly, it will bolt right into your 901 transmission. However, you will need some longer studs on the engine case in order for them to extend far enough into the Porsche tranny's bell housing so you can thread the nuts on.

All you need to do is use your Superbeetle 12v flywheel but use a Porsche style diaphram assembly with the clutch. A Heavy Duty 200 mm friction disk is what I used with the Porsche Style diaphram assembly. The Porsche style diaphram has the individual fingers at the centre instead of the ring at the center of the diaphram that the VW clutches use. The fingers will interface correctly with the Porsche 901 transmission's stock Throw Out Bearing.

Now the only thing you need to consider is that the Porsche Starter will only engage into the Superbeetle Flywheel teeth approximately one third of the way since the VW flywheel does not stick out as far as the Porsche 912 Flywheel. Many say that this will wear out your Flywheel's starter teeth prematurely and others told my that they used it like that without problems.

My soloution was the remove the starter motor and then remove the rear aluminium housing off the starter that contains the starters mounting flange. I simply mounted and machined the housing on a lathe in order to remove about .100 inch off the flange surface. Basically speaking, this allows the starter to extend further into the transmissions bell housing so that it gets more bite on the flywheel and it covers more of the flywheels teeth surface thus reducing the wear on the flywheel ring gear teeth.

For exhaust I used a regular four into one Type 1 extractor with a regular single glass pack muffler that came with it and it fits fine except the exaust pipe exits under the right side of the valance panel other than the left side as the original 912's pipe did. If you can live with the half moon exhaust pipe cut out on the valance being on the right when you pipe is on the left then no problem. Otherwise, you will need to do some welding the change the muffler around.

For engine tin use the stock or chrome VW engine tin with the stock 912 Porsche Tin surrounding the engine. In other words, cut and trim the Porsche 912 Firewall, rear tin (over the muffler), and two side pieces to fit to the regular VW tin on the engine and bolt it together.

For a rear engine mount use a Type 2 bus mount adapter plate on your Type 1 engine block and use the stock 912 rear cross mount. Jack your engine to the correct level once it is installed into the car with the front tranny mounts installed then use some 2.5 inch angle iron to span between the bus adapter mount and the 912 cross mount. I used two pieces of angle iron for the left side of the pully and two on the right. Now just weld or bolt them together so your engine is hanging in position.

Go to my 911/912 pages through my web site at www.geocities.com/clarkblumberg for more info or email me.
Have Fun, Clark.
