engine swap , anything smaller then a type 4, goal being 100hp ,smallest engine possible Options

[thelogo]

I'm desperate to ditch the 1.7

But not looking to shoehorn anything huge in there

I'd prefere to have a simple install with plenty of room to spare

I figured that the smallest engine possible would be an advantage

So are there any tiny boxer Subaru motors
Or

Something that fits better then others



And please weigh in

Advantage and disadvantage

Realistically, any older car is going to have trouble at some point. You can fix it yourself, or you can have someone else fix it. No shame either way.

Swapping to a different power plant is going to take a lot of work. If you're not doing that work yourself, that means a lot of money. If you go to a good shop, make that "a whole big lot of money". Going with anything other than a very well-understood and well-documented setup that has been done many dozens of times means that you'll find "interesting" issues to solve. Which means more time and work, which means more money.

It might be cool to have the only Geo Metro-powered 914 in existence, and to get 45+ MPG and real heat and AC. But would you pay $100K for it?

The simplest thing to do is to keep the 1.7 and drive it.

If you're worried about problems from engine heat, get some reliable instruments installed. (I mean stuff like the Aircraft Spruce head temp gauges. Not cheap stuff.) Install the under-car flaps to help pull cooling air through the motor, make sure the stock cooling system is all there and in good shape, and then drive it.

If it still gets too hot, then consider what you can do to cool it down. Maybe changing the tune (e.g., the spark timing, the mixture), maybe ducting more air into the engine bay, maybe adding an external cooler, or maybe something else. But don't worry about those unless and until you find that there is an actual problem.
