After a considerable amount of research it looks like the following three options are my best choices for a 1973 914 1.7L rebuild.
1. Rebuild the engine the with the same displacement. This would require honing out the cylinders and installing new pistons. 2. Rebuild the 1.7 as a 2056. This would require new cylinders, pistons, rods, 2.0 cam and possible matching to make the valves bigger. Then new valves. 3. Buy a 2.0L motor, increase to 2056 by buying new cylinders and new pistons. All of this assumes the heads are not cracked or need repairs. It appears that option 3 would be the best if I can get a 2.0 liter motor cheap. Plus option 3 would allow me to not have to split the case if there are not any issues. My car has been sitting for about 25 years and has around 80,000 miles on it. My dad was the original owner. The buyer never did anything with it. He parked it on a concrete slab with a roof over it and put a cover over it. Opinions and advise? |

I will likely be selling a rebuilt 2.0l by spring.
Have two builds in process - one for me and one to sell to offset cost of a six I recently acquired. |
