First, I'm the owner of a 73 914 with a 1.7 liter engine that has bent/broken intake valves. I'm not a mechanic, but the cost to repair this part seems to be as much, if not more, than finding a running engine and putting it into the car.
With that said: Can I 'drop' any 914 engine into the car??? 1.8 -2.0?? Is the mechanic correct, will it cost me nearly the same amount to simply find (FAR FROM SIMPLE) a running engine and have it put in the car??? Can I 'drop' any of the larger engines into the car without any problems??? ___ next level questions_____ Anyone with any ideas of the causes for a 'big bore' engine to RUN HOT . there is no thermostat connected to the engine and after about an hour of running it starts heading into the red zone. -for direct contact: Rfranklin@price-entities.com -during the day (pacific time), Riccif@cts.com -at night. I would really really appreciate anyones help/response. I'm always greatful to this board and point eveyone I know in its direction. My current 914 was purchase after many hours of discussion on this board and it is a gem. The ENGINE was damaged due to mandatory driving on the face of the MOON in order to get to work for nearly 3 months (streets on my way to work -were pothole infested- caused serious damage to exhaust/engine -though again, according to what I have learned I simply have an 'intake valve -bent/broken' issue). |

Unless you are planning to have a knowledgeable 914 engine guy pull the heads and redo everything wrong with the top end on that 103mm engine stay away from it!
I own a 2.2 short stroke engine like that and I have worked on another in the past year. There is a lot to get it right with those animals. The parts can't simply be assembled with out checking every little detail. The current owners problems will only get worse in your hands. My guess is the cylinders aren't fitted properly to the case, since they don't fit at all right out of the box. Minimum cost to cure will be $750-1000. In addition the engine absolutely needs an external oil cooler to prevent overheating. BTW, there's nothing wrong with 40IDFs on a 2.2 short stroke engine if it has a mild cam and the carbs have bigger venturis and correct jetting. In fact it could even be more driveable than with 44s. Do you know what are the valve sizes? My recomendation would be to purchase a running 1.7 from someone doing an upgrade or pull the heads off your current engine and fix them. If you find the right mechanic it probably won't be as painful as your current mechanic is telling you. |
