Two cylinder cars

I once owned a '78 Chevette and a '82 Ford Escort, each with 1600 cc, 4 cylinder engines. They made about 60 HP, and consistently got about 40 mpg highway. I was happy with them. So, 60 HP is enough power for small cars.

More modern engines are much peppier than the old engines due to 4 valve cylinder heads and fuel injection. For example, GM's 2800 cc 4 makes 175 HP. A twin cylinder 1400 based on this engine would produce almost 90 HP. Thats 50% more than my old Chevette 4!

2 cylinder cars should get mileage similar to hybrids at 2/3 the price. I'll bet that a 2 cylinder Chevy Cobalt would get well over 50 mpg.

Why can't Citroen or Honda build 2 cylinder cars again?

My Honda n600 is 2 cylinder,

My Honda n600 is 2 cylinder, but it also is carbed and uses points and condenser.

I would love to put a water-cooled fuel injected 2 cylinder engine in that thing.

Maybe the only solution is a water-cooled motorcycle engine.

Don't motorcycle engines

Don't motorcycle engines make 150hp?? and rev past 12000rpm?

That is a good combo. But the problem is then you would need different gear ratios for the tranny. You can't just put a different motor and expect your gears to work right with the motor.

Some maxima guys are putting in VQ35's in their maximas that had VQ30's and most can't even use 1st gear.

Just like car and truck engines, each one is different.

My n600 engine gets 35ish HP, and revs past 8000RPM if I push it. I imagine most 600cc engines have similar power.

Yes, plus matt's engine is a

Yes, plus matt's engine is a motorcyle engine in the first place, if we get technical about it.

Anyway, any sort of transmission adapter plate can be built of the most part, you could prolly put and ITR tranny with LSD on the n600 if you wanted to spend the money to do it,

Motorcycle engines

Motorcycle engines make lousy car engines.

Motorcycle engines (with the exception of Harley Davidson) are designed for high rpm power instead of low rpm torque. They do this by making the bore much shorter than the stroke, and by using a lot of valve overlap. Also, most motorcycle engines use carburetors, which are not nearly as good as fuel injection.

Putting a motorcycle engine in a car won't result in a big mileage improvement in a car.
