Why, it's simple.
Just cut out the 2 center cylinders of an aluminum case and weld the ends back together....prolly ought to do the same with the cam towers. Minor issues include custom cams, crank, intake manifolds, cam covers...yada and about $15-20k. Got a sawzall? Piece of cake

Some guy in CA does it....figures.

they cut off 2 cylinders

Very expensively.....

Posted by: airsix May 16 2003, 01:57 PM

I want him to cut a motor in half and ADD 2 or 4 more, not remove 2.

ps - Ahh heck, make it 6 more. I'll call it "the centipede". Hmmm... Might have to move the tranny back a little.

actually, it would be much easier to just weld 2 4cyl. engines together ...
take the flywheel off one, the fan off the other and weld the cranks together!

a "cheap" 4.0 liter flat /8

I hate pushrod motors. Ugghhh. If I'm spending big money I want overhead cams, dry sump, aluminum cyls...

I love my 914, but I just barely tollerate it's leaky rattling powerplant with it's anemic 47hp per litre.

while i do agree with you on that i still think a "double" /4 would be a way cool project!

Posted by: airsix May 16 2003, 03:05 PM

Yes, I admit it would be cool. It's been done at least a couple of times. I've seen pictures of a bug-in in Europe where someone showed up with one. Also saw one in a magazine when I was a kid.

Basically that's what the factory did... they called it a 912 engine and dumped it in the back of something they called 917

cheers,

Supposedly, someone was going to make new castings for the 911 four-banger, not sure if it ever materialized or not.


Want a 8 cylinder flat motor?

It'll never work.

Oops. Ok. They were lucky.

Welcome to Friday.

Here is a cheaper motor, (I would think, but by how much, who knows??)

Type I bottom end with Subaru heads (watercooled)


If someone wants to give me set of Boxster or 996 heads, I'm sure I could figure a way to morph them onto a Type IV

The factory already does this with the factory cars...the GT2, GT3 use an aircooled block with watercooled heads....the bore spacing has not changed in ages on thier 6 cylinder motors.

Yes, I know. Lovely little monsters weren't they? Hard to come by now-a-days though.

I love Porsche history. (wish the present was as bright as the past)

Later, they even turbo-ed them

cheers,

Jeroen

Posted by: krk May 16 2003, 06:36 PM

So we all know you can't turbo a /4, but I guess you can turbo /4+n? Hm. Wait a sec. there might be one in my driveway.....

917's rule. To me, in many ways, it's a "golden age' or a snapshot where the right rules come together with the the right manufacturing skill to produce something that is just amazing.

As you can guess -- turbo P cars are big with me!

will this engine (dubbed 911/4 ) fit into a volksawgen beetle or ghia? i smell a 5 speed v dub conversion

Posted by: Scott May 16 2003, 11:19 PM

Actually there are 2 guy that I know that make cut down 930/4 cases. One is Chuck Beck that makes the Porsche Spyder Replicas and the other is a friend of Kevin Jeannette (owner of Gunnar Racing) named Dean Polopolus. Yes they are 15-20 grand to do one. It is much cheaper to put a Porsche 6 in. But if you must have a "Porsche" 4 then these are sweet. They put out 200 hp. Twice that of the type 4 engine and it can take the stress.

Posted by: airsix May 16 2003, 11:41 PM

Whoa! I want more info!! This looks awsome. (although just dropping in a wrx 2.0 might be a lot easier)

The only place I've eyeballed one is at Gary Emory's place in Micminville (sp?), OR. He has a campout/swapmeat each summer.
