Random question
Does anyone know why the k20 looks like its the opposite way round in the engine bay to other honda engines, with the inlet at the front of the engine bay and exhaust mani running out the back. It looks like where the airbox is at the back of the bay isn't a good place to get airflow. If the enigne was turned 180 degrees it would be layed out like or honda engines with the induction system running down the left side towards the front, inlet main at the back and exhaust mani at the front. Anyone know why they choose to do it this way lol

gives the exhaust better flow

I think its the sencible way to go, as the hot exhaust mani is at the rear and the cold intake at the front.

Straighter exhaust setup helping flow and also no exhaust running under the sump meaning that you're not heating the oil up as much (Spoon actually make a specific heat wrap kit to put over the sump in engines where the exhaust runs under the sump) and also the engine can be set lower in the chassis helping the centre of gravity.

Also, in racing, most cars have ITBs and they're better off sticking out towards the grille for maximum airflow.

Although in s2000's the k20's sit sidewards so manifold is on the left and intake runs down the right

apart from that the s2000 does have a F series engines, not K ones...

The S2000s have F-series engines (either 2.0l or 2.2l) and the engine is mounted longitudinally as the car is rear-wheel drive.
