[3d914]

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,

First let me say a big THANK YOU to Tom ( a local SHO rail owner) for allowing me access to his shop to get the necessary dimensions. Tom's been using SHO motors in his rails for years and has amassed a great deal of data and insight into these engines - including turbos & super-chargers. (IMG:style_emoticons/default/drooley.gif)

Here's how it came out. The engine of choice for a longitudinal mount would be the 3.2L used in the automatics. One main reason is that the 3.2 has a single auto-tensioning serpentine belt, whereas the 3.0L has two and require manual adjustment and more space.

Take a look at the final best-fit I can come up with.
Magenta - engine bay and body parts.
Red - 901 Tranny
Green - 24" dia wheel/tire
Blue - engine outline



Here's a few things I have to consider:

1. The centerline for the crank is just below the seam where the oil pan and block mate. This leaves the stock oil pan in place with no mods and out of harms way.
2. The 901 transaxle will need to be brought foward and down 1" in each direction. Its likely this will move backward as the adapter plate and clutch may require more depth than I allowed.
3. The angled part of the trunk will have to be removed and re-aligned up to match the adjacent vertical wall. That way an extra rib can be added to the trunk and it can still be sealed properly, with space for luggage.
4. The firewall at the seats will have to be modified. I don't mind eliminating this as I was going to do a custom back-pad anyway, and I never have my seat all the way back.
5. The center section of the forward part of the trunk lid will have to be cut to accommodate the intake & throttle body. The TB can be rotated vertically and air could be fed via a custom ram scoop. I'd even considering adjusting the engine height upward slightly so that the intake manifold can be exposed. (IMG:style_emoticons/default/idea.gif)
6. THe only other BIG downer on the whole deal is the weight. Fully dressed, this engine comes in at 500 lbs. That is first hand info, not second hand speculation.

Now the tough part. Do I proceed? (IMG:style_emoticons/default/idea.gif)

Man, thats a lot of work for 220hp and 500lbs. Practical answer, I would do a suby. But if you want the challenge, then.......
