This 914 belongs to my neighbor. It is one of the original 914s built by RPM in Florida back in the... '80s (IMG:style_emoticons/default/confused24.gif)

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. |

924 Porsche forced induction...can't turbo that one either. MSDS kit was available a couple years ahead of the factory 931.

QUOTE(Porscheman @ May 4 2016, 03:42 PM)  QUOTE(r_towle @ May 4 2016, 06:30 PM) 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 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. |

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. --DD |
