When I wrote into the SAABnet forum, asking for advise on installing cool side-pipes on my '68 Sonett, I was stoned severly. I'm hoping the purists of you will please excuse the following "imagine if" question, as I seriously would like to know...
Could the entire engine + automatic trans. from an early '80s VW Van be easily fit to my 1970 914/4? "Easily" might not be the right word...maybe "possible"? I know there have been Subaru engine swaps onto Porsche 5 speed but could an Subaru automatic transmission + engine be adapted to Porsche axle? What-ever process and combination of parts...Does anyone know if there have been successful AUTOMATIC 914 projects? Thanks. |

Well,
The 914 is mid engine, the van is rear engine. The tranny for the 914 is unique to the 914. The motor for the 914, the 1.7, the 1.8 are both bus motors... The 2.0 liter porsche motor is for the 914. So, the motor will fit, provided its not water cooled, it will fit right in. The tranny is another story... I have heard that an audi tranny from the audi 100 might fit, but no one has yet tried. so, if you search here, look at the automatic tranny threads and you will find lots of information on that topic. Welcome to the club!!! Rich |

you would have to flip the automatic transmission for use in a mid-engine car. not sure how you would go about that ... (IMG:http://www.914world.com/bbs2/html/emoticons/unsure.gif) Andy |

It might fit but the gearing would suck. Vans are made to haul large amounts of cargo and not go fast.
For example, my Vanagon tranny is made to work with an engine with max power from 2000-4000rpm. At 70, and in 4th the engine is whining along at 4000 BIG RPM. Ken |

I stand corrected... I believe the 1.7 and 1.8 have the oil dip stick in a different location... Rich |

I have seen a 914 with an Audi 3 speed automatic in it. Guy loved his 914 but couldn't drive it due to the loss of his left leg to diabetes. So he had a shop install the automatic. They even used 911 sporto pedals so it looked stock.
It was a 1.7, and it was slow as a dog. Tranny bolted up to the engine with a bus flex plate. Custom axles and a custom rear mount completed the conversion. |

1.7 bus motors had dual Solexs as did some 1.8 bus motors. Really the 411/412 1.7 is the same as the 1.7 914
Find a Sporto tranny and use that to get a auto matic 914. (IMG:http://www.914world.com/bbs2/html/emoticons/popcorn[1].gif) |

There was a 914 with a automatic in it on Ebay last year. I believe he used a tranny from a audi. It ended with no bids! (IMG:http://www.914world.com/bbs2/html/emoticons/confused24.gif)

Do you need an auto? It's been done. Someone at one time even posted pics of the Audi conversion. It's a lot of work to convert. Because of the power an auto trans would rob, and the diffeculty in matching shift points to the engines torque curve, I think it would be less than a desirable match.
I would think it would be better to install a complete Suby and do the radiatior in the back like Scott Thatcher. I would think you could even run the turbo version for some added punch. |

As mentioned, the direction of the tranny would be problematic as it is made to go infront of the engine. However, for more power and to go completely away from stock you could use a corvair engine as it will rotate in the direction you need and have more power. Can you say /6? I am not sure of the type of problems this would cause int he tranny, though. They are not used to being run backwards.

I'm thinking 411/412 auto tranny. Cheap and easy to find. I'm not sure if we can flip the diff or not? Good question.

If you can't flip the ring gear, it might be possible to turnt eh tranny upside down to get things turing the right way, oil drain ,a nd breather would need to be relocated, but I don't see why running it upside down would not work.

Automatics keep the tranny fluid in a pan on the bottom of the tranny. You can't flip them due to the location of the pan. The Audi transmission is designed to go behind the motor. No modification of the tranny is required to work in a 914. |

So is it that there is no room in the case to flip the R+P? Is it such a big deal to simply cut the case where needed and weld on a cover? I realize its a special skill to weld aluminum (the T3-T4 cases are aluminum right?) but there are welders that know how to do it...

Has anyone put a front wheel drive transaxle into the back of a 914?
I would have thought maybe using a V6/auto tranny combination would have some alure to non purists who just want to drive a cool car and have fun!! Besides, a GM 3.8 could give you 200+hp and alot of wheel spin!!! (IMG:http://www.914world.com/bbs2/html/emoticons/w00t.gif) |

The old vw autostick used a vacuum boosted solinoid that was triggered by a switch in the shift knob. Bassically when you pressed the shift knob, the clutch would disengage,and you could shift, no need for the left foot. The later VW's had more of a true automatic tranny.
The vacuum boosted hand operated clutch might be the way to go,a nd that tranny i am sure can be run upside down, or if old enough I believe the ring and pinion can be swapped side to side (old swing axle style) which can be converted to IRS. The possibilities are endless. |
