When the decision was made to convert to watercooled, the next thing was to decide which engine.
I Had a couple of criteria:
- engine cost
- mileage, or, kilometerage…..(is that a word?) The engine should have enough km left in it.
- the engine lid should be able to close normally, so a boxer engine seems the most logical
- ease of maintenance
- not too much horsepower. Too much horspower will make it more un-economic, and I would have to upgrade the rest of the beetle (brakes, suspension etc.) which would cost too much.
This led me to two choices: a Subaru engine or an Alfa Romeo engine. And because the Alfa Romeo engines were better available, it became an Alfa Romeo engine. I must say, I also have something with Italian cars, I drove Lancia for 8 years, and loved it.
The engine I choose came out of an Alfa Romeo 33, this one:
And this is its a 1.4 injected engine:
The great thing about this engine is that is has a wasted spark system on it (only on the 1.4 engines and some 1.7 engines), which means it does not have a distributor, which is often a cause of problems on a car, and you don’t have to set the ignition timing ever. Furthermore it has hydraulic valves, which means it doesn’t need valve adjustements! And the injection system (from Weber) means no carb-adjustments! I figure, as long as all the sensors are working correctly and the wiring is allright, it should run.
It has about 90 pk (In Hp’s it’s a little more), which is allready 40 pk more than my current 1600 vw engine!
