Naturally aspirated engine or NA engine stand for engine which has no forced induction such as Turbocharged or supercharged. This type of engine depend 100% on the engine to suck all the air to provide a better Volumetric Efficiency.

Most super car like Ferrari and Lamborghini use NA engine for their car. NA engine usually rev higher than forced induction engine. This type of engine is more complicated. 5 valve per cylinder, very high compression, short stroke engine are the criteria for NA engine. Some manufacturer playing with NA engine for a quite long time such as Honda. Honda are well known with their v-tec engine. A Variable Valve timing electronic control. It use both electronic and mechanical thingy to switch their 2 camshaft. Mitsubishi motor comes with such a system called MIVEC (Mitsubishi Innovative Variable Valve Timing Electronic Control). And Toyota with their VVT-i system. These Japanese car manufacturer are not alone. A German car manufacturer called BMW has their own style of variable valve timing system called VANOS. Why these people wasting time playing with NA engine while we can easily gain more power from forced induction? The answer is the response of NA engine.

If you ever heard a v-tec from any Honda civic type R, Honda Integra or NSx, your definitely love the sound. Or maybe a sound coming out from drifting ae86 which has converted to AE111 engine. Or perhaps, engine sound from M3 and M5 car. All these car has the sound that will make any car lover cried.

Sadly I cant afford any variable valve timing engine. Not right now, so I guess im just happy with my NA engine without variable valve timing. I love to tackle a corner, and NA engine is perfect for me so i can rev high without worrying too much since NA engine is a high end engine. Any short stroker NA are born to rev as high as possible, BUT term and condition must be apply!
