This should do it, I guess
EDIT.: THIS one should do it.
Challenge for you.
The year (and technology year too) was 1989. It became a milestone for Cossack Autos. The company's first engine with fuel injection instead of carburettors was made. As you can expect from Cossack Autos it had some drawbacks. The 1.8 engine was heavy (but not that much), and it had only 70 hp of power (which was only competitive with diesels of that period), but it was practically indestructible. And it was VERY economic. And VERY cheap. And, actually, it was pretty difficult to design.
Let's get back in time.
The year IS 1989. You are the head engineer of Cossack Autos. The guys above gave you specifications you must achieve.
After some reading...
-HOW THE F...HELL I AM SUPPOSED TO MAKE THIS?!
-You said the same kind of crap when you were developing 2200S engine.
Use fuel injection (it'd be impossible without it anyway)
