Well, I have done some research on the sportomatic cars, and I have decided to build one myself. (IMG:style_emoticons/default/biggrin.gif) It will be a 914 for my mom, because she doesn't like to have to use the clutch...because she is too short (exatly five feet).. (IMG:style_emoticons/default/chairfall.gif) We found a nice solid car, good price, and it has airconditioning...which my mom specified it *had* to have for her to drive. Sportomatic 914 base My dad called us while we were driving from Virginia to Atlanta today and told us we won it...Then I asked her what color she wanted it to be, and the first car she liked she said "that color" it just happened to be a mini cooper... It was orange with black stipes, so that will be my theme. I aim to start and complete the project over next summer, while working at a professional porsche racing shop that pretty much deals with older race cars. I need a list of parts that I need to start collecting to make this work. It really shouldn't be hard to do...after I figured out how everthing worked... So far I have:

-901 Sportomatic transmission
-911 sportomatic pedal cluster
-911 sportomatic shifter and tigger
-torque convertor (it was a VW unit..just not sure exacly what model..I have it saved on the comp somewhere)
-transmission oil temp gauge
-I think I need and extra oil pump to pressurize the system..still a little confused about that part

What else people?? I need to start looking for parts because of their rarity.

Do I need to? It could probably be done, that is why I am working at a racing shop next summer....I'll do the work like mowing and cleaning up and stuff and he will teach my the business...

If it was driven off one of the cams, how would I get it to work on a T4? Could I run it off the flywheel? (I dont know anything about it, so that may be a very stupid question)...

uh yeah.... (unless you want 1 forward gear and a few reverse LO)

or mount it upside down...

the 914 sporto HAD to have a flipped diff (or the motor spun backwards NOT)

Check into the T4 411's and 412's. Most of them seam to have been sold with Automatics. You'll have all the T4 auto pieces you need.

ok, the oil pump on the 911 sporto was driven by a cam..so why would I need to do a mechanical pump?? Couldn't I do an electric oil pump??

I have a 411 1.7. It was in a auto car. I may still have the flywheel. But if you find a non running 411 auto stick you may be able to flip the diff and use the T4 stuff to make it work. I know less than nothing about how the Sporto works. Great Project. No question on this subject is dumb.

P.S. I do know the axles don't work and the brakes and all the other stuff are not the same. So you may need to play with axle flanges and stuff to get the axles to bolt to an auto stick.

so, a learning question...why use the cam to run the pump? wouldn't it spin faster as the RPM's went up, also causing the pump to work harder??? More pressure at higher RPM's???

I guess Rick and I have no f-ing clue..LOL

411+412 has ALL the pump parts/flex plate and torque converters you need. Auto trannies from these cars can be had for $150

I *THINK* they ran the pump off of the oil pump cover much like a dry sump setup.

Forget the electric setup.

So where can I get these parts?? I checked ebay and I barely found anything at all for a regular 411 and 412.... the samba? Local VW junkyard?
