Why bother with an S4, he put a 300 hp Euro motor in there. Based on going through all 19 pages of the thread, I do not see that there is room for a centrifugal blower in that installation (there cannot be 2 inches between the front of the motor and the drivers spine), a TS might go on though.......

 

it would be so much easier to put in a 3.6 or make a 3.8 and put it in there. think how much lighter the engine would be!! very cool to hear V8 sound out of cars like this though,i must say.
kind of reminds me of a twin turbo V8 chevy in a 911 over at the CT shop. the owner just passed away after the project was completed. it was always a V8 911 and real cool workmanship! Now, with over 550hp, it was a complete monster (Frankenstein!)

The heads when gone through will flow 400hp or more. (Huge valves), and if they are on a 5.0L, no-one would miss the 4V.

 

He mentioned price as the reason he did not do a flat six.

 

Before you run out and snap up a 914 roller chassis, consider the fact that either the centerline of the axles must move rearward a few inches or the engine must penetrate the firewall a few inches. This guy chose the later. I've seen this car in person. I've also seen an example of a well done 914 w/928 engine done the other way: axle centerline moved rearward. It was way better than this car. It was at the Monterey Porsche Parade in 1990 0r 91 or whatever year it was. I concluded that the better way is to move the axle centerline rearward but that is costly. The way this guy chose is simpler. Does anyone want to hazard a guess about the torsional rigidity of the 914 minus the firewall diaphram? I guess it is significantly worse than an original 914 which means not very good. But then what do I know about 914s?

Now don't jump all over me, but why not simply put in a chebbie? There are kits available to make it more than easy to do and several examples running around. And cheaper. A 914 roller can be had for $500. Throw away all the stuff you don't need (lots of stuff) and stuff a chebbie in it with a 915 transmission. Done. Simple. Cheap. Parts everywhere, even at Midnight Auto Supply.

 

I fond that a german did an S4 engine in a 914:

Ron: You are correct sir. The chevy is smaller, lighter (by over 200 lbs I think) , shorter, has less width, and would be a 5.7L instead of a 4.5.

But he said early on he wanted to participate in the PCA stuff, which as we all know is a snobbery of elitist ****** who say a Chevy motored 914 doesn't count. A 924 with an audi truck engine yes, but a hand fabricated 914 with a small block would not.

 

Sorry, I agree. I'd rather have a Porsche with a differing Porsche transplant than a chevrolet any day. It's just that more interesting & remains purley Porsche. Power/cost are irrelevant to purists.

Then again, my last 3 928's had forced induction, so what do I preach??

 

Rick uses the same username here too. Search for posts/threads by user "918-S".

I met him, and he said he did a 928 motor because he wanted to keep it "in the family", and besides there are lots of chevy-powered 914s.

That's a really sweet car.... I'd love to take it for a spin!

The 914 with SBC conversion kit is explained on this site. FWIW.

 

And spin it would. Every 914 I have seen at an AX that spins or loses the line, SPINS LIKE A TOP. As in a two 360s before I could blink.

 

yeah but being dizzy is fun.

 

When I put 200 lb rear springs on my car, it would want to spin when changing lanes. Gots ta be careful about balancing that car front to rear.

 

Ron, you have to give the guy a heap of credit for all the creative work he did. He is clearly a VERY clever guy with a deep passion for the marque...... Your average affectionado wrench only DREAMS of having the skill this guy has. I would pay money for his creation way before I would even look at a crate engine frankenstein.... I don't know what this guy does for a living, but he is a genius with a wrench.

 

He seems to be some sort of machinist fabricator for his real job. When he posted the pic of the pistons, I wanted to write back and say they weren't the 10:1 ones, but it was like a year or more that he took the head off. The 10:1 pistons for the 4.5L are a high top, not flat, but I was ultimatley not sure if this was a 4.7 or a 4.5.

 

I give anyone credit for trying, and even for partially succeeding, rather than passing it all off and making excuses for failure. I have seen the car. As I recall, he said then that there were issues. Of course there were issues, and one of them is torsional rigidity. He said he will address them, and no doubt he has. Perhaps he has solved this problem in other ways using braces not visible in the photos. Personally, I'm one of those purists I guess because I have a 914/6 and two engines; one is an original six (well, almost original...an original case 2.0L), and the other is a better than RS spec hot rod 2.7L MFI. I hate to think about how much is in the 2.7L but it is a Porsche engine all the way including the MFI pump. And I agonize over fender flares for the car which would make possible larger brakes and rubber. And personally, I would not want a 914-chev hybrid for the same snobby reasons. But if someone wants one, its his car. I know a guy at my gym who just yesterday asked me how he could put a Chevy into a 914 for fun 'cause he understands chevvies and not Porsche engines. That's cool for me. He doesn't want to go through the learning curve to know the quirks of the P car engines, so I turned him on to Renegade Hybrids. My only real concern with the 928 in a 914 is the difference in length and I spoke with the man who built the 914 with extended wheelbase that I saw in Monterey, and he had lots of agonizing stories to tell of the transformation and pain to achieve that result. The chevy eliminates that pain for some. For the guy that built this 928 hot rod, it obviously isn't pain; it is passion.
