Well,someone out there in the hinterlands of the E.U. must have a handle on these lightweight V8s. If not,an Opportunity exists to meet the demand for the unique small 4+8 zylinders. Other than auto applications,a kitplane aero app may move a few of them. Simply gather as many pieces that you can and put up an Ebay/Samba for sale sign. I'm somewhat surprised that a VW/Porsche fan from the Continent hasn't considered a powerplant of such attributes. A further question regarding the dimensions of the bore spacing and cylinder stud pattern remain unanswered. Scaling a photo may derive a close number,but only close.
Judging by the positive reaction on virtually every blog and posting for the last decade,a surprising number of wrenchers would like to have such engines. And to think the Ford V8 of '32 was it's contemporary. In hindsight now,it's no surprise that the ArDun head for the Fhead Ford used a similar,independent latest big breathing pentroof/crescent design. An aftermarket to develop hotrod parts for the engine never happened. Rollertip rockers,rollerlifters,modern valves,all the things you would do to your aircooled VW,Porsche,Corvair,Hirth,Rotax... I haven't seen anyone other than the factory turbo the engines,so,you could be the first. Could be fun.
A nice one,utility,military application,Will fit nicely into a 914,a 4x4 914! Yes,a 924/944 early differential,cvs,axles,a custom upright to carry the hub. A few details and some hotrod tech,and a short stroke turbo screamer to make it all good. A good deal if you can acquire them. A quest for a European,or a source of parts for the next custom X-12. Not only possible,but imperative.

Have you seen these? Both are design built around the 914 unibody. Either would be interesting to refine/update.

Weird. The front is definitely five-bolt, the rear looks like four-bolt.
EDIT: Looking at the pics on the website linked shows they were all five-bolt. So the four-bolt look must be an illusion. Probably the "uneven" part of the bolt pattern (where it does not match with the eight spokes) is out of sight on that rear wheel.

Sure,a great idea,rather than purchasing an off the rack auto,make a custom. California is a goldmine of automotive design/build talent. Start like we all did,scratching our "Lambo"with a pencil on the back page of notebooks.Mockup scale models and when the results please you,move to full-size mounted on the recipient Fiero chassis.Beat alloy panels into shape over wooden bucks like Bertone or layup into a mold pulled from a buck. So yeah,a huge effort is required,and at the end you may have something like a Bradley or (hopefully) a Frua 914.I suppose that is why I can appreciate the results Eberhard Shulz attained with his Imperator 108 in the '70s.A verbatim replica of others work would not suffice,so he designed and built his own.An achievement like that requires more than a passing knowledge of design and manufacture. It all starts with an idea,so determine what your quest is then blaze a path. Click to view attachment a good example of a nicely integrated design
As you observe various auto designs are you able to percieve rust and or dents from a distance of 100 yds?Sure,so it is entirely possible to detect the shape of the fenders of a 911rsr.Expedient measures to cover the tires range from this to the shapely splined flanks of the 914. The necessity drives the invention.
Post #90543 Click to view attachment funny thing,found. from this angle it looks better. the addition of discrete features+nasa ducts (edit:07/09/16) A relic of the past,it has grown on me.
The engineering that went into the stamped steel chasssis produced a rigid crash safe exoskeleton. The only production mid of America. Check the prices of that poor car and compare to any other mid. (edit:05/05/16) 80 mph transverse rollover crash tests passed.
The more I more I consider the cylinder heads of the 4cam 613,the more I'm inclined to think they may fit quite easily onto a Corvair shortblock. Gears are turning here. A flat 6 or 8 from the Carpathian Mountains.

Click to view attachment Side view with cam tower exposed showing lifter-block registers and seats. A custom barrel to carry a roller lifter can be fabricated to seat in the existing bore.
(Edit:10/21/14) The stud spacing appears to be wide enough to accommodate an 90mm bore cylinder. Visible cylinder bore is 75mm,so perhaps as much as 90mm(+15mm) Anyone out there have real specifications of the head stud spacing? (as resolved from drawing,102mm bcd)
edit:an 80mm(+8mm) stroke would yield 4.07 L,an increase of 1.5L .

The numbers here are very close,so,a maximum bore diameter of ~90mm. The cast iron lifter bore bodies are seen attached to the cam tower.Custom versions made to carry roller lifters would fit nicely. At the bottom,one of the oil coolers is seated on it's seal flanges,the temperature sender at the top of the stud. The distributor barrel is at the right.

Isdera Erator GTE,Eberhard Shulz. I even like his first off. There was a yewtube of it being thrashed through the black forest,driver's view.(now removed)
With the sump pan removed,you can see the main bearing cap that carries the axle. Note chain driven oilpump and filter mount,starter to the right.Aluminum bearing caps are cross-bolted,the block rails extended far below the crank CL,perhaps suitable to carry structural loads. Mounting the block in front of 901 TX seems possible although the uneeded portions of the casting create a 5-7 kg weight penalty,easily removed.
A unique design modification,to allow the use of the engine in a mid configuration. The original driveshaft is used to drive a cv joint where the differential formerly was. A new casting is made to carry the diff,raised from the factory position,dropping the CG,and pan to ride height. The engine is run with a crank and cam position trigger,for coil on twin plug ignition,no dizzy. A conversion to chain drive for the cams,and vvt takes less room at the drive end of the block. A hyvo chain to drive a shaft going forward to a front diff,can make for a awd car.
Since the axle is too far forward for a 914, you should... Weld the diff like a spool, mount the engine transversly, install a AWD drivetrain and make the first air cooled V8 AWD 914. The transmission diff will act as the transfer case.

The original intent of the designer was to package an entire powerplant and drivetrain into a light compact discrete component.A twin engine 4x4 for example would only require installing an engine package as there are no auxilary peripherals needed,being aircooled.An engine over the axle is a design suitable for front drive and or rear drive and is suitable for adaptation to other applications.Mounting the engine in place of a 914's 4 cylinder,you gain displacement and a few pounds that theoretically at least,is easily shed.I can find no faults in the design and a few unique solutions that simplify the manufacture and maintenance of it.The engine has no inherent problems with pulling studs out of the block or bearing failures,as it's a robust ribbed casting.
Click to view attachment This is really cute,but somehow the taillights and bumper look too modern for the bug roofline.Perhaps a little Ghia,?
Stuffing an early '63 914 with a 2.5 to 4.4 Litre V8 of an aircooled design has to be OK. Turns out there may be as few as 10 Tatra V8 engines in North America. There may be a HotRodder in the EU who may wish to give it a go. The 4-cam 613 could run with the heads swapped for a hot-V. Convenient for turbocharging and intercooling plumbing.
Like this Outlaw POLO 356,the '63 914 has a rounded,curved house. If the hips pinch in at the tail,and the roof-line blends into the vertical face below the trunk-line,a nice Ghia like curvature will result.Voluptuous. Add a little sponson and the two lamp treatment. Very 60's retro.
Liquid cooled? Requires a rad in front. A very sophisticated look also from the 924/944/968 product lines. Well done.I even like the color. Raised brand logo on rocker is a nice custom touch.
Chrome Yellow bright pearl.Now with accent stripe in Lime. WB stretch,18" ATS + Michelin RR sticky.A nice flat TurboSix to motivate. Rusty 914 + Honda crx roof,hammered into a shape that looks '90s. The Honda roof a tribute to the iconic 911 curve at a fraction of the cost.
Another look for the CRX roofline transmogrification. Honda did a nice rendition of the tapered b-glass. Fits on a Fiero too,transforming the early windscreen slope to a more modern look,911-ish. I recall Chuck Beck(edit:Randy) did a 914 > GT1 custom roof that I liked.Without all the accoutrements of wings n poorly shaped flares,running boards and air dams it looks ok.Quite reserved but sporty enough to turn heads even with standard power.Really brings the 914 shape into the '90s.
You are bouncing around a lot. What was that v8 aircooled motor? What years, what countries was it produced?

The Tatra aircooled V8 was built starting in the mid-30s. It was in several models, and went up into late 90s. There may have been diesel truck motors that went later than that.
It would be complicated to import the Tatra V8,whether the early SOHC, pushrod or the later quadcam. There is some unrealized potential in these sturdy alloy engines,400hp has been bandied about as the number. The block casting of the 613/700 has that unique integral differential housing,placing the crank 1-1.5 in above the axle. A very nice design in every way,unappreciated in markets in which it never appeared. The engine sitting atop the axle in a 914 would,I'm sure,ruin any handling features of the car. Placing it mid however,you would have a light powerful aircooled V8 with the added bonus of an all Teutonic 914. The small displacement and stroke makes possible the use of a flat crank and cams plus the heads can be turned for a hot vee exhaust layout. After all,an aircooled V8 design would enhance the awesome factor of any 914 build. The difficult part is having a few shipped to your garage at a reasonable cost or any price,just to begin work. The sound of a 308 GT4 emanating from a 914 would be worth it all,the work being large in dimension. Be the first on the pit row with a twin turbo version to catch the latemodel of your choice.
A 911 roofline melded to fit,looks very much factory. Haven't found any reference to a design studio proposal similar to this. Remarkable how the Cayman has retained such lines. The 914's curves look nice ,even now.

I have absolutely 0 skills at photoshop, but maybe somebody would like to photoshop a 1973 Boxster for us? Take a 73 914, and graft the front end of a 73 911 targa onto it.
I want to build one in real life, and put a Boxster emblem on the back.

More like an impressionist painting in oil than anything else. Incredible that it's stock below the beltline. Looks very modern,telling how far ahead the design of the 914 was in '67.
