need engine advice

I grew up a 914 that my dad drove. It was a 1973 1.7L. When I went to college in 1985 I took the car with me. A year later the engine got very tired. My dad bought me more reliable transportation. One weekend I came home my beloved car was gone. My dad had sold it.

Fast forward 34 year later and I have found the car! It was painted shortly after being purchased but never fixe up. I have the opportunity to buy the car back. I know the engine needs to be rebuilt. I do not know if I want to rebuild the 1.7L or find a 2.0L engine or doing a v8 conversion. I will take any advice you can give me.

I have a 2.2 liter 4 and man did that wake her up. I bought it that way, but tinkering with it sure is nice compared to my project car. The project car getting a 3 liter 911 engine, it’s expensive and slow going and the 6 is much more effort. I’m really glad to have the 4 for autocross and track duty right now, will prob keep it as a big four even though I have a 2.7 911 core on the shelf I had planned to put in it.

I would really consider keeping the four, but looking a little beyond 2L.

The question of "should" isn't something anyone but you can answer.

If you figure out what you want to do with the car, that will help narrow down your options.

Enjoying the car as it was originally designed would mean rebuilding the 1.7 and keeping the injection. Originality also has some value, but with the repaint (and probably repairs) it likely will never be a super-top-dollar car anyway.

Since the car did come with a 2-liter engine as well, getting a 2 liter would also be an original-type experience. More power is often more fun, though by modern standards any original 914 motor is pretty weak.

The V8 conversion is, I think, more involved than many people realize. Most of the problems have been addressed over the years, but there are a lot of solutions to choose from and some work better than others. (Cooling system, exhaust, mounts, etc.) And some things, like the transmission, may need a good chunk of money thrown at them to solve reasonably.

The Six conversion is always fun, but again is more involved than most people understand.

What are you looking to get from the car?

Do not put a V8 in the car! There are a number of things you can do with the 1.7, such as a stroker Try your best to keep the car original.

Should be able to find a running super cheap - I would be looking for one to swap into the car to get it on the road while giving you time to go through and build your original engine however you want. Exactly what I did for my 74 1.8

2056 motors are a really sweet spot imho. More power than an original 6.More tq too. Keeps the original cars balance and sound and ease of operation. Also, ease of install etc.
