914 1.7 to a 2.0 (VW), 914 1.7 to a 2.0 (VW) Options

[PTP]

Hello All!

I'm new to this forum as I have recently bought a 1970, 1.7L, 914. The engine needs quite a bit of work and I'm considering to replace it by a 2.0, from a vintage VW.

Would you say that such engine would work/fit in the 914? Are they visually alike? Would there be the need of a great adaption in the car?

Thank you in advance!

I would recommend to overhaul the 1.7 instead. And while it's out, consider to go to 1911cc by switching to 2.0 cylinders. It's easy, cheap and guaranteed to work. If you want to do it properly, use a 2.0 crankshaft and heads as well. That should give you something in the region of 90-95 HP, I nice boost over the 80 HP of a stock 1.7.

...consider to go to 1911cc by switching to 2.0 cylinders. It's easy, cheap and guaranteed to work. If you want to do it properly, use a 2.0 crankshaft and heads as well.

You have to go to 96mm P&Cs to get 1911cc from a 1.7 or a 1.8. (Note: The 96es that fit into 1.7 heads are mighty thin at the top; it is generally a better idea to cut the heads to fit the 96es meant for 1.8 engines.)

Using a 2.0 crank with its 71mm of stroke will give you 2056cc with the 96es, but you have to specifically use pistons made for the 2.0 crank and rods, or you'll have rather low compression. The stock 2-liter motors were 1971cc; 94mm bore by 71mm stroke.
