Just a first impression of what the econoEngine will look like in the car. I've just added three cylinders more, adjusted the timing, totally refixed it because of the ****ing glue together bug even if I didn't use glue together, and not much more for now!

Remember: accelerate with UP, it starts automatically.
v2: Mah god, it's a lot better now! I've moved the timing a little and the engine goes at 20 rad/s more, and much stronger!
v3: I've changed the springs that moved the "ignition plugs" up with stiff axles, and now it doesn't blow up!
3.1: Fixed the accelerating system, added a little box for fuel zDepth
v4: At least, it has reached 100 rad/s! Thanks Gent!
The camshafts aren't colliding but two boxes and a little visible circle, they're there just for looks.
I've changed the accelerating script so that it works with a var, and now it accelerates! (it didn't even do before but it should)
Staggered 2nd and 4th cylinder so that the engine has more power and stability, and changed the cams timing so that it reaches AWESOME 100 RAD/S! (it didn't even get to 70 rad/s before)
v5: Now you can move it! And the balls will stay in the cylinders!
