OK here goes . . .

I sold my beautiful Ravenna 914/2.0 so I could develop a custom 914 in good conscience. The sweet Ravenna was to stock to cut up and customize, & an admiring buyer wanted to return her to full stock - so it seemed like the perfect match.

Now I've found a 74 1.7 that someone has already led down the path of the Dark Side (as the puritans see it), and I'll simply take it the rest of the way. Just as a warning - this is not meant to be a factory GT look alike or anything close. I want to incorporate some of my own ideas and those I like that others have done. In fact at this point its not even going to be a Porsche six. My initial intent is to go with the Ford 3.0L SHO. Plans may change when I get to that point, but that's where I'm headed.

It seems reasonable to start with Before pics, so heres a couple of the car before I started any dismantling:

OK - latest progress.

The engine build continues. Did a valve-adjustment on new years eve, and have numerous plastic covers cleaned, painted, and ready to install. New engine pics coming when I get it all buttoned up.

Next issue I've been playing with is the intake. The huge, but cool, intake manifold on the SHO requires an equally large throttle body that is preceded by a MAF sensor.
So the dilemma for me has been how to route the intake air from the engine lid to the throttle body without giving up my entire trunk. Here's a couple of things to keep in mind:

1. This is a custom 914, not a restoration!
2. Throttle body points to the rear and extends slightly above the rear trunk lid. A fiberglass cover will be made for this.
3. The inake diameter into the MAF sensor is 3.0 inches
4. The output diameter of the MAF sensor is 3.5 inches.
5. I plan to change the trunk hinging so trunk opens from the front.
6. I don't want to loose the trunk completely. This still needs to be a weekend cruiser.

So here are three variations I've come up with for the intake. I've modeled them in 3D just roughly to get an idea of how each will look. Thanks Mark for the base 914 surface model.

Over the Top
This method routes the intake from each side of the engine lid, through filters, then back up and over to the center, where they meet at the MAF sensor, then curves down to the throttle body.





Side Run
This method routes the intake from each side of the engine lid, through filters, then directly rear through the trunk wall, over to the center and to the MAF sensor, then slightly up and into the throttle body.



Down the Middle
This method requires a custom pedestal in the center to mount a wing. The pedestal will house the air filter and box to blend to the 3.5 inch outlet needed on the input side of the MAF sensor. The intake and MAF will route directly down the center into the throttle body. Most of this should stay hidden under the trunk lid, although a custom cover will still be needed for the throttle body itself.
