None of this is hard, not the case, not the crank, cams, cam towers, etc... It just takes serious $$$$ to do one off parts.

Hell you could 3D print all this stuff in PLA and sand cast it.

Again very doable, but my friends with serious money are not into 914s. And they would not drop a dime on this project. So you have to find a combination. Someone who loves 914s, and the 914-8 specifically, and the monetary means to pull this project off.

Engineering and building wise, is the easiest part of the build.

But @Mikey914 I am currently not happy with you. I find that my spare time now has been spent figuring out how to do this. I don't need another project in my head right now. I have about 5 of them that have been designed and ready in my head. 914-6 restomod. 914 EG conversion. an AWD Karmann Ghia with Subaru Power. A Dual cab AWD Subaru power. A Willys Pickup with X-drive and a N54 swap. And now a 914-8 with a working 3.0L 8 cylinder, making about 400HP. This does not include all the machine tools, and workshop projects I have yet to build.

But the one that is kicking me right now is transmission. So many choices beside 908 box.

I should have stuck with building scale models, so much cheaper, and I could have all these cool car ideas that as of right now, I can not afford but a couple.

Let me add one to your list that has been in my head for a long time.

A W12 VW Phaeton engine and Boxster/Cayman six speed transmission in a 914.

The engine and trans share a common bolt pattern for the bell housing, the clutch parts from the Cayman should work. Maybe need a custom flywheel. Fitment should be no problem as engine is actually shorter than a 911 six cylinder. Put a Cayman rear suspension under it. Use a V-8 radiator kit. Aftermarket EFI.

Then you can have a real 914-12.

I like it The W8 would be a good fit also

Ask Catorse how much he has into the tooling for new 3.6 cases. I think it's north of quarter mil.
Also ask him how "easy" it was to do.

https://www.taorminaracingdesigns.com/produ...-6-engine-case/

Easy, and he is building for a market. This would be a one off.

Okay well if it goes like a 906 windshield, I will have to make 10 to get the one I need.

The W12 - W8 engines are an interesting piece of engineering, never got to the point of wanting to swap them in anything.

And I keep coming back to if I am building a 914 with all the comforts, and handling of a Cayman, then why not just build the Cayman. It is a really awesome chassis.

The only reason the W-12 idea has not already been done is they are hard to find.

As someone who designs engines for a living, I'd have to say, "Yes, you are off your rocker." Unless, of course, money has no meaning to you.
That said, IF you have the ability to build the cast tooling yourself, it might not be a mortgage your house endeavor. And at that point you may even create a bit of a market for a '908 build kit' for guys considering -6 conversions or building 904 replicas...
Because let's face it, why would you go through all the effort for a 911 soundtrack when you could listen to something closer to this:

@914forme I'm not happy with you for that idea like you're not happy with @Mikey914

Yes I have the capability to make my own tooling. I do enjoy challenges. Don’t want to take too much away from making new parts, but this is probably a 3 yr project for me. I don’t know if you call it a form of ADHD, but I tend to focus on multiple problems at once. I tend to actually enjoy it.

That is why Electrics racing will always be lacking ....the auditory orgasm

Dude, if you've got the ability and facilities to build your own tooling, the desire to do it, AND the time to do it, then please take this project on! No doubt you'd receive plenty of moral support from the Porsche community, myself included. I'm even tempted to offer help creating the math...

Why not ask the factory if they still have the tooling & molds? Be easier to do with a super organized group buy Also, it's OEM

Lets be honest here.. Catorce spent 1 mil on his project.. The 5 axis cnc was 350k alone.. Not including tooling,a building, staff, then designs and prototyping. I have spoken to Adam a few times as he is a huge 914 fan.. It would likely be easier to team up with him as he is 3/4 of the way there.. He has the machining and molds handled now to add 2 more cylinders..

I keep seeing the word easy being thrown around in this thread.

There is no easy button.

928 motor with carbs. Not perfect but it's a tribute not a clone.

Or 2 Corvair motors if that hasn't been mentioned. The fan is in the right place

"Easy" in the way that it can be done with out inventing a new form manufacturing or other item.

"Easy" by me is never meant to imply it will not take work, and time. It is meant more as this is not like trying we are trying to control particles and move billions of atoms across a time space continuum.

It will cost some serious money, time, and there will be problems, all projects have them. I can see why the term Easy used in the common way like the Staples ad would make you think well minimal effort required. Like anything worth doin, it will requires lots of blood, sweet, and tears.

@tomeric914 Your welcome

Both Pauter and Scat build spec cast T-1 (style) aluminum blocks. At least at that point with some engineering, fixtures, tig'ing ; mate the 2 blocks together= a flat 8 block.
Scat also builds custom spec crankshafts at small quantities, and this is welcome news for a venture project like this.

NOONAN does billet cases.......no casting...

Ok, the factory car has a 908 engine and trans. That’s really cool. The rest of the car is sort of ugly and only cool because Porsche built it. So say you made some sort of Frankenstein air cooled 8, got a 914 trans to fit the longer engine and modified a normal 914 to look like the factory car. Do you end up with something good or just something a 914 guy would find interesting.

A lot of time, money, and effort spent to simply get V8 power but with lower Center of Gravity. I guess you get bragging rights sort of the same as this joker below. Sure they did it but its a crap motorcycle if you actually want to ride it don't want to have to start multiple motors to go for a ride or 1/4 mile run and likely get beat by a stock Hayabusa.

The other issues that issues that I haven't seen addressed as part of "easy" is adressing the torsional osciallations of the longer crank for an eight. Sure the factory did 8, 12, and even 16 but they were having a heck of a time with crank torsion and they had real casting, engineering, and development Dyno's at their disposal.

At least the motorcycle is a good ad for the engine brand. Any engine in a 914 is pretty much hidden away. You see some carbs, a fiberglass shroud and that's about it.

I'm still fascinated about how the conversation may have gone...

"Ok, so we have this new chassis...and we're tossing a VW Bus engine in it??"

"Yup" [in German, translated]

"Seems like something better should go in there...what about that 911 engine?"

"Cool" [also in German, translated]

"Wait...isn't Franz working on that new 3L FIA Group 6 engine...?"

"Here, hold my bier" [natch]

We can philosophize all day long but the most realistic idea would to be to call Noonan and see how much to add 2 cylinders to the design.

https://noonanrace.com/products/911-porsche-case

Call Arrows and have the custom crank made

http://arrowprecision.com/pages/crank-shafts

Call Webb Cams and have cams made

http://www.webcamshafts.com/

Call AT Power and have an Intake and throttle body set up made

https://www.atpower.com/porsche-products

Then drag it to Marty @ MSDS or Burns stainless to have custom headers made.

I would love to do a setup for the 8.. Click to view attachment Click to view attachment

Phaeton’s are not hard to find, there is one local for under $15K... no idea what to do with the rest of the car.

I was at Chuck Becks house for a Christmas party about 8 years ago and there on the garage floor was a 4 cylinder 911 engine. He was telling us (talk about a bench racing session) about he was protested for running a 2.0L 911 engine in a racing 914 because it was not a 4 cylinder . He said the rules only said 2 liters . So he cut down a 6 case to 4 cylinder 2.0 L 911 engine . I think he told me that Scat charged $5000 for a crank. He also had a 12 cylinder engine there which he built a motorcycle around . You can see that bike on J. Lano I think

The crank wouldn't be that difficult, you can have one machined from billet steel. Less than $5K.

I had not thought of this. Seems like a better route. I have access to a 6 axis machine, so may be the way to go.
