...or rear two cylinders, as it is.
Um ... the two middle cylinders.

Yes, but the entire 912 philosophy (don't tell them the factory was just using up the leftover engine supply) is a lighter, more nimble car with better balance.

A six would ruin the entire 912 mystique.
Eric Shea

Here is a article that covers Eric's point of the left over 616 engines and Porsche's first try at a 4 cylinder Porsche engine.
From what I've heard Porsche will be offering a turbo 4 in the next couple of years.
By the way. The 356 SC made 95hp. The 912 engine was slightly detuned to 90hp to make it easier for first time Porsche owners to drive in the city.

Dean only cut 2 cases. A ruined mag case for a trial fit and one 3 liter case that he made a working engine out of. He has a degree in mechanical engineering. He then designed a 4 cylinder case and has it cast out of aluminum.

912s are a little better balanced because the weight of the motor sits more forward than a 911 motor, as well as reduced motor weight.

My '67 (911) started out in life as a 912. I was planning to convert it back and have two 912 motors for it ('68 and a '69). I also have most of the components to build up a 1720 including a complete case.

I'll probably sell the '67 'as is' and keep the 912s as spares for my '66.

I took the alternator out to have it checked. Rated at 50 amps but produced 60 amps. With fuel injection and the lights on I probably need more like 75 amps. I'll deal with that this winter along with a couple other projects. I took a few pictures. At 8000 miles the engine is dry as Mohave bones! This engine is unreal. Wait till you see the other 912 POLO engines coming down the line. I talked to Dean for about a hour the other evening. A couple of 60 something guys just jacked about what we're doing. 1 in KC, 1 in Spain, 3 in CA, 1 in Asia. One of which is like a 2.8 with a monster cam, BIG ports, etc. My car is FAST, it will be killer. I can't wait for all of us to get together in a year or two for a drive. Over the next year or so I'll have some neat additions for my car. Life is truly very goodAttached Image Attached Image

Hijack......
That AC compressor mount in post # 7 looks ideal for a 914 4 cyl.
Just substitute a rotary unit to reduce size and gain smoothness.

Wow, wish i had the money!
1720 in my 356sc is awesome, but a polo would be awesome-er.
Does the kit include p/c and heads or are those buyer purchased.

They should be adding 2 cylinders to the flat 6 not taking 2 away. (IMG:style_emoticons/default/biggrin.gif)

With a horizontal fan to reduce the overall length.

That would be a sick motor.

The flat 8 is indeed a awesome engine better suited to the 914 than a 911 or 912.
A POLO 4 is fast enough for me and the weight behind the rear axle needs to be kept to a minimum on the SWB cars.

Also if you contact Dean mention the 912 Registry thread to get in on the offer.

Very cool! Thanks for adding so many pictures!

The only thing I don't like is the collectors on all of the exhausts; they seem like they converge far too quickly.

Would love to see this installed. On my wish list for a future 914 (specifically a '70 or '71).
