I spoke to Bernie about 10 or 15 years ago.
he told me he lost money on every turbo kit he sold because of all the bench racers and tire kickers. he had to spend countless hours answering phone calls and talking to potential cuistomers who never bought anything. In the end he threw it all in a dumpster and said good riddance.

And ferg's right, you can't turbo a 914.

Hi I'm new to 914 world ..I want to install a small supercharger on my 914 via fuel injection a small 5 to 7 psi boost ..I seen a turbo installed on a factory fuel injected motor on this page ..do I need to add a blow off valve? ..was going to install directly from super charger to my black rubber air intake hose .would like some feedback ..from anyone who supercharged or turbowed there cars .thanks .try not to laugh to hard ...but as I pass you ..going 120 .mph ..if it don't blow up ...that is .....

Since this thread has been dormant for more than 3 years, you get credit for getting that off on just the second post. Nice.

You can't turbo a 914.

You also can't supercharge a 914

Also I seen the black 914 supercharged ..but he used a custom intake and blowthrough fuel injection with computer from an exspensive efi system ..that u can adjust via computer ..I'm sure he Has a built up motor too ...

Why can't you supercharge a 914 ..they have turbos .and superchared 914.s or are you guys just messing with me ...as in the old qoute .....

It's an old and long standing joke...

The issue you will have is limited support for the setup, there might be less than 100 in the world that have done this.
And, the head to cylinder sealing is gonna leak, so you will need to keep the boost down and design a method to seal the head better when things get bad.

The 911 turbo, and others, have used basically a guitar string machined into the head and cylinder to assist in sealing them.

It's not a low cost road to go down, but there are many member here that have turbo setups that work.

Thanks for your input ..I was going to install a small Subaru ple 500 .supercharger made for small displacement engines ..as I want to run the stock fuel injection ..and set up
.rather going with a turbo ..and all the expensive efi blow though desings ..figure the supercharger is small and has a self contained oil set up ..and is cheap to build..and probsbly only pushes 4 to 6 psi anyways

I'll try adding 5 lbs extra when I install my new oil seals .on the stock head tourqe spec.s as I don't want to break the studs ..and hoping it runs good with the lower psi output ...that it offers may run great ..wish me luck ...

This 914 belongs to my neighbor. It is one of the original 914s built by RPM in Florida back in the... '80s

The "You can't turbo a 914" joke started back in the late 90s on the Rennlist 914 email forum. It was in response to Jenny's brother attempting to turbo a stock D-Jet engine.

For all of you who have not been around here as long as some of us, that response is a running joke. We all know you can, but all of us want to be the first to post it in any thread about turbocharging.

I suggest you buy a book or two on the subject of supercharging.

Then I'd spend some time researching this supercharger....

http://superchargersunlimited.com/specs.html

Making the engine larger via biggest pistons and cylinders you can find (which makes you sound like a 12 year old and I doubt you really want to spend that kind of money) will require a bigger supercharger or this small supercharger to be overdriven so much so that it will just turn into a heat pump, something which is not good at all for the supercharger or the motor. You can only remove so much heat from the compressed charge.

Longer ago than that, even. The "fine" folks at "european car" magazine told someone who write in that you cannot turbo a 914. Sammy G, and Jeff Shyu (Jenny's brother) and a couple more were actually doing it at the time, and ejm's and Evill Ed's were in the works.

It developed into a running joke from there.

Sounds very under-researched. Just get giant pistons, huge crank, massive cam, huge supercharger. Bigger is better, so what could go wrong?

That sparks an idea,hmm..and a question.
Other than Porsche and Bruce Crower,has anyone turboed a Flat-8?
