Right now this car is a running 1972 914 with a 901 trans converted side shift, and a 350 SBC V8.
Salvage title car, registered etc. Calif. BMW 320 calipers up front. Renegade conversion. So there are many engines that work good in a 914. The stock 914 4 cyl is about 180 pounds. (I am not sure if that is bare long block or dressed motor complete.) The iron V8 with iron heads is about 525 pounds complete. I have a motor that is a 4 cyl. that is 225 pounds long block and about 330 pounds dressed with a turbo. It can put out 300-500 hp with equally high torque. I have a 6 spd transaxle that adds a bit of weight but is far better. So why is this 1.8 liter engine so much stronger than the original Porsche 914 1.8 liter engine? The picture on the top is the naturally aspirated 914 head, the picture below that is the new engine's with a turbo force fed head. Yamaha was in on the creation of this head. "An engine's power is limited by how much air can flow in and out of it." Roughly quoted from some smart guy. This engine has more valves than the Chevy V8. Attached image(s) |

Greetings JB6000:
The Audi transaxle looks very similar to my Audi 6 spd 01X which has 108 mm flanges. I had adapters machined to take the 108 mm >> 100 mm Porsche 944 / 911 CV's. Because the ttranaaxle is offset (centre line) I started with 5/8" adapters recessed bolts to Flanges, used 944T CV's and 911 axles, I believe the axles were 18.5" and 20" (going by memory). After several months realized that the right axle was too short, but after some re-measuring decided to keep what works and then machined thicker adapter on right side; seems to be the best solution. (custom axles would be costly and difficult to source). Sorry I don't have more in common with your project since I am running a Z06 LS6 motor out of a 2004 Vette; and closer to 400HP. Enjoy the project and wish you good success. Allan |
